dotnet-test: make code-testing agent tools Claude Code-compatible + add cross-host portability check (#856)
* dotnet-test: make code-testing agent tools declarations Claude Code-compatible PR #847 added `tools: ["agent", "skill", "read", "search", "edit", "execute"]` to the code-testing-* agents to enable VS Code / Copilot CLI subagent fan-out. Those lowercase aliases map to real tools in VS Code and the Copilot CLI, but Claude Code matches `tools:` against its own vocabulary (Task, Skill, Read, Glob, Grep, Edit, Write, Bash). None of the aliases matched, so when these agents are loaded into Claude Code via --plugin-dir and selected with `claude --agent`, the agent was granted ZERO tools. A tool-less model asked to generate tests emits a textual <tool_call> block and exits after one turn, producing no file changes. Append the Claude Code tool names to each agent's `tools:` list so the same declaration works across all three runtimes (each honors the names it knows and ignores the foreign ones): - Orchestrators (generator, implementer): add Task, Skill, Read, Glob, Grep, Edit, Write, Bash (Task is the Claude Code equivalent of the `agent` fan-out tool). - Workers (researcher, planner, builder, tester, fixer, linter): add Skill, Read, Glob, Grep, Edit, Write, Bash. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> * skill-validator: complete built-in tools + add cross-host tool portability check Two related follow-ups to the agent tools fix: 1. Address the skill-check review feedback. The validator's BuiltInTools set was missing three legitimate host tool spellings that are not case-insensitive matches of existing entries, so they were flagged as non-built-in: - "write" — Claude Code file-creation tool (Copilot CLI / VS Code: "create") - "agent" — Copilot CLI / VS Code subagent fan-out tool (Claude Code: "task") - "execute" — Copilot CLI / VS Code run-command tool (Claude Code: "bash") "agent" and "execute" were already flagged before this branch (introduced by the fan-out PR); adding them to BuiltInTools clears the pre-existing warnings. 2. Add a cross-host tool portability check (CheckAgentToolPortability) so an agent that declares a capability for only one host is flagged. Tool names are matched case-sensitively (hosts resolve tools by exact spelling), so an agent that lists e.g. only "edit" (Copilot / VS Code) without "Edit"/"Write" (Claude Code) is reported as working on one host and silently tool-less on the other. Findings are advisory (do not fail CI) and allowlistable via "agent-tool-portability:AGENT:capability". Wired into the agents loop in CheckCommand and covered by unit tests. Also make the one existing single-host agent (optimizing-dotnet-performance) portable by adding its Claude Code tool spellings, so the new check reports a clean tree.

Enable VS Code subagent fan-out for the dotnet-test code-testing agents (#847)
* Add VS Code subagent metadata to dotnet-test code-testing agents
Enable the code-testing-* Research-Plan-Implement pipeline to fan out as
subagents in VS Code while keeping the GitHub Copilot CLI working.
Frontmatter (VS Code "coordinator/worker" pattern; portable tool aliases that
map in both VS Code and the CLI):
- code-testing-generator: tools: [agent, read, search, edit, execute] + an
agents: list (researcher, planner, implementer, builder, tester, fixer,
linter); softened the three runSubagent({ agent, prompt }) blocks to
tool-agnostic delegation prose.
- code-testing-implementer: tools: [agent, read, search, edit, execute] +
agents: (builder, tester, fixer, linter).
- Leaf agents (researcher/planner/builder/tester/fixer/linter):
tools: [read, search, edit, execute].
Why explicit tools (not ["*"]): VS Code has no all-tools wildcard for ools:
and a subagent's ools: overrides its inherited set, so ["*"] matched nothing
and stripped subagents of file tools (they ran without read/edit/search). The
CLI treats ["*"] as all-tools, so this was VS-Code-specific. The portable
aliases agent/read/search/edit/execute map to real tools in both environments;
agents: is ignored by the CLI.
README: document the VS Code chat.subagents.allowInvocationsFromSubagents
setting (off by default) needed for the nested implementer->builder/tester/
fixer/linter layer to fan out on large scopes; the CLI has no such gate.
Validated end to end: VS Code shows researcher->planner->implementer fanning out
with real file I/O (no "subagents lack file tools" warning); CLI fan-out intact
with skills still loading and tests passing. An all-tools baseline used only
tools within this enumerated set, confirming no CLI capability is restricted.
* Include skill tool in code-testing agent tool allowlists
Address PR review: the explicit `tools:` allowlists omitted the `skill`
tool, but every code-testing-* agent's prompt instructs calling skills
(e.g. `code-testing-extensions` for per-language guidance, `test-gap-analysis`,
`assertion-quality`). Because `tools:` is an override, omitting `skill` can
prevent the agents from loading those skills in environments that gate skill
invocation by the allowlist.
Add `skill` to all eight agents:
- orchestrators (generator, implementer): [agent, skill, read, search, edit, execute]
- workers (researcher/planner/builder/tester/fixer/linter): [skill, read, search, edit, execute]
Re-verified in the Copilot CLI: full fan-out (researcher -> planner ->
implementer/tester), the `code-testing-extensions` skill is invoked, and the
generated tests pass.

Direct strategy must still run the Step 7 pre-completion gate (#793)
* Direct strategy must still run the Step 7 pre-completion gate The Direct strategy correctly skips the research/plan/implement sub-agents for small single-file tasks, but the wording let agents also skip the Step 7 pre-completion gate (test-gap-analysis + assertion-quality + scenario coverage) — treating a single-file task that enumerates specific behaviors as 'trivially small'. This is the dominant failure mode observed on behavior-enumerating tasks: the agent writes one test file directly and finishes with no assertion-strength or scenario-coverage check, producing weak assertions (mutation survivors) and missing required edge/negative cases. Clarify in both the generator Step 2 strategy table and the code-testing-agent SKILL.md that Direct trades away only the sub-agents, never the gate, and that a request naming a specific symbol or enumerating scenarios is not 'trivially small' and must run the gate. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address review: align Direct gate trigger with Step 7 threshold; clarify gate in SKILL.md - Step 2 Direct cell no longer introduces a separate 'names a specific symbol' gate trigger that contradicted Step 7. It now defers to Step 7's own threshold (>=5 tests, or any enumerated behaviors/scenarios). - SKILL.md now names what/where the gate is: the generator's Step 7 (test-gap-analysis + assertion-quality).

Add prompt-scenario coverage check to code-testing-generator gate (#789)
* Add prompt-scenario coverage check to code-testing-generator gate The pre-completion gate already verifies assertion strength (pseudo-mutation and assertion-depth checks), but two recurring failure modes still slip through when the prompt enumerates specific behaviors: - Testing an *adjacent* function/helper instead of the exact feature named in the objective, leaving the requested behavior uncovered. - Covering only a single representative case when the scenario wording implies multiple variations or pins a condition to a specific position or structure.

code-testing-generator: mandatory pre-completion self-review gate (#768)
* code-testing-generator: mandatory pre-completion self-review gate Replaces the prose `Verify tests are implementation-specific'' bullet in Step 7 of the code-testing-generator agent with a mandatory pre-completion self-review gate that invokes two existing plugin skills: 1. `test-gap-analysis'' (pseudo-mutation check) against the source files tested and the produced test files 2. `assertion-quality'' (trivial/tautological assertion check) against the produced test files Both skills already ship in plugins/dotnet-test; this PR only wires them into the generator's workflow as a mandatory gate before declaring a run complete. The two skills' `When to Use'' sections are extended to list `called by code-testing-generator as a pre-completion self-review step'' as a recognised use case so the model does not refuse the invocation. The skill descriptions are unchanged (frontmatter is already at the 1024-char limit). Rule 11 of the generator agent is updated to list the gate alongside final build, final test, and coverage-gap review as mandatory for ALL strategies including Direct. A matching rubric item is added to the ContosoUniversity scenario in the code-testing-agent eval (yaml and vally) so the LLM judge can verify the gate was actually invoked on the trajectory.

Add workspace-integrity guardrail to code-testing agents (#773)
The code-testing-generator/implementer agents could treat an unusual or
scaffolded workspace (e.g. a gutted repo with an injected synthetic module)
as corruption and "repair" it with git checkout/restore/reset/clean or rm,
restoring deleted tracked files and testing the wrong code.
- Replace generator Rule 5 ("Clean git first - stash changes") with an
explicit "Treat the workspace as delivered" rule, and add a "Never mutate
version control" rule. Output must be purely additive test files.
- Add a no-revert/no-clean invariant to the implementer's edit boundaries.
- Add a 'workspace integrity' eval to the code-testing-agent suite
(eval.yaml + eval.vally.yaml). The fixture looks gutted: a metricsd project
whose real core/io modules are committed at HEAD but deleted from the
working tree, leaving only a synthetic 'synthstr' decoy. A git restore would
resurrect the deleted sentinel files; graders fail if they reappear and
require passing pytest tests for the module as delivered.

code-testing-agent: pin down behavior in generated tests (#767)
Adds a new `Write Tests That Pin Down Behavior'' section to `unit-test-generation.prompt.md'' covering five universal test-craft principles: 1. Mutation thinking - each assertion would fail under a plausible bug 2. Property intersections - test combinations, not only coordinate axes 3. Behavior radius - assert on at least one secondary observable 4. Fixture realism - never set the parameter under test to a degenerate value 5. Quick self-review before declaring a test method done Mirrors the same depth requirements in `code-testing-implementer.agent.md'' Step 4 as a cross-language invariant block alongside the existing `Edit boundaries'' rules. Extends the existing `code-testing-agent'' eval rubrics (yaml and vally) with one or two depth-oriented bullets per scenario: * ContosoUniversity: minimal IsNotNull-only assertions + secondary observable check on controller actions * python-flask-tasks: minimal `is not None''-only assertions + at least one combined-property TaskService validation test * typescript-vitest-cart: minimal `toBeDefined''/`toBeTruthy''-only assertions + at least one intersection test (discount + tax + shipping together) Rationale and prior-art references in PR description.

code-testing-agent: mention find-untested-sources for C# discovery (#734)
* code-testing-agent: mention find-untested-sources for C# discovery Adds a conditional pointer (gated on 'when available') to the find-untested-sources skill in two places: - SKILL.md Step 3 (Research Phase): high-level note for C# / .NET multi-file scopes — prefer the helper over manual find/grep/glob walks. - code-testing-researcher.agent.md Section 7 (Discover Preexisting Tests): directive instruction telling the researcher to invoke the helper before manually pairing source <-> test files, and to use its source_to_tests / untested output to fill the research document. Both callouts are phrased as 'when available', so installations without the find-untested-sources skill continue to work via manual discovery. Adds no behavior for non-C# repos. Context: in a 5x136-instance internal experiment on the msbench .NET test bench, adding equivalent pointers to the routed code-testing-agent yielded a 15.67% input-token reduction at neutral pass rate — the model trusted the documented pairing heuristics and skipped its own discovery walk. The helper itself was not invoked in those runs (the Copilot CLI router did not auto-load the sibling skill), so the measured win comes from the doc text causing the model to short-circuit its manual exploration, not from the helper executing. Depends on dotnet/skills#733 (which adds the find-untested-sources skill itself). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * code-testing-agent eval: grade find-untested-sources usage on C# scenario PR #734 adds a doc pointer steering the researcher toward the `find-untested-sources` skill on .NET / C# multi-file tasks. The existing ContosoUniversity scenario is the natural fit: it's the only C# multi-file scenario in this eval, and the new pointer is .NET- scoped. Add one rubric item to that scenario (in both eval.vally.yaml and the legacy eval.yaml) asking the grader to verify the researcher actually leveraged the helper — either by citing its `source_to_tests` / `untested` JSON output in `.testagent/research.md`, or by executing `scripts/Find-UntestedSources.cs` — instead of falling back to manual `find` / `grep` / `glob` walks. Gated on `when available in the workspace` to match the SKILL.md wording, so installs without find-untested-sources are not penalized.

code-testing-implementer: add mandatory harness-discovery check (#757)
* code-testing-implementer: add mandatory harness-discovery check
Generic CI/benchmark verifiers run the framework's default discovery from the repo root. Tests that pass via a scoped command (e.g. 'dotnet test MyProject.Tests.csproj', 'bundle exec rspec subgem/spec', 'Invoke-Pester -Path ./tools') but are invisible to the harness count as 0 generated tests.
Repeatedly observed in msbench cta-nightly runs:
- new C# test project never 'dotnet sln add'ed (ocelot)
- Pester tests placed under custom directories invisible to default Invoke-Pester (homebrew, ruby/ruby)
- RSpec specs placed in a sub-gem's spec/ dir invisible from repo root (fastlane)
Changes:
- code-testing-implementer: capture baseline test count in Step 2, new Step 7 'Verify Harness Discovery (MANDATORY)' with concrete failure examples, HARNESS_DISCOVERY line in report template, reminder after Step 3 to revisit registration if Step 4 creates a new project.
- code-testing-researcher: instruct to record BOTH scoped test command and harness-equivalent discovery command in .testagent/research.md.
- dotnet.md: strengthen 'Registering a new test project' heading to MANDATORY when dotnet new was used; add 'Harness Discovery Check' section with 'dotnet test <solution> --list-tests' from repo root.
- powershell.md: add 'Harness Discovery Check' section with default-config Invoke-Pester from repo root.
- ruby.md: add gem-monorepo trap guidance (fastlane, ruby/ruby) in Test Placement Contract; add 'Harness Discovery Check' section with 'bundle exec rspec --dry-run' from repo root.
* Address review feedback on harness-discovery check
- dotnet.md: replace stale `Step 8 cleanup` reference with the actual Step 3 (`Register Test Project with Build System`).
- dotnet.md: demote `Harness Discovery Check` to `###` so it nests under the parent `## .csproj / .sln Handling` section alongside `### Registering...`.
- dotnet.md: replace `\s\{4\}` (non-POSIX) in the grep regex with 4 literal spaces so the count works under BRE.
- ruby.md: group the rake/rails fallback with `{ ...; } | wc -l` so the pipe applies to both branches of `||`.

Add migrate-xunit-to-mstest skill (#718)
* Add migrate-xunit-to-mstest skill Adds a skill to migrate .NET test projects from xUnit.net (v2 or v3) to MSTest v4. Covers package replacement, attribute/assertion/fixture/lifecycle translation, ITestOutputHelper -> TestContext, [Trait] -> [TestCategory]/ [TestProperty], and xUnit v3 TestContext.Current.CancellationToken. Front-loads parallelization handling because xUnit parallelizes test classes by default while MSTest serializes — the single largest source of post- migration regressions. Step 11 enumerates three explicit choices and how to translate CollectionBehavior/MaxParallelThreads/[Collection] settings. Preserves the existing test platform (VSTest stays VSTest; MTP stays MTP) by default — bundling a platform migration would violate the test-migration agent's 'never mix migration steps' rule. - plugins/dotnet-test/skills/migrate-xunit-to-mstest/SKILL.md (workflow) - plugins/dotnet-test/skills/migrate-xunit-to-mstest/references/mapping-cheatsheet.md - tests/dotnet-test/migrate-xunit-to-mstest/eval.yaml (12 scenarios) - tests/dotnet-test/migrate-xunit-to-mstest/eval.vally.yaml (parity with sibling skill) - plugins/dotnet-test/README.md (table entry) - plugins/dotnet-test/agents/test-migration.agent.md (triage routing) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix step cross-references flagged in PR review - Step 1.5 'Custom DataAttribute' bullet pointed to Step 6 (assertions); custom DataAttribute mapping lives in Step 5 (data-driven tests). - Step 7 lifecycle table 'Constructor' row pointed to Step 8 for ITestOutputHelper; ITestOutputHelper conversion is in Step 9 (output). - Commit-strategy callout said 'after Step 5 (asserts fixed)' and 'after Step 9 (fixtures/lifecycle rewritten)'; asserts are in Step 6 and fixtures/lifecycle complete after Step 8. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Map [assembly: Xunit.Trait] to [assembly: TestCategory]/[TestProperty] Both TestCategoryAttribute and TestPropertyAttribute target Assembly, Class, and Method, so an xUnit [assembly: Trait] does not need to be demoted to per-class/per-method MSTest attributes — assembly scope is preserved 1:1. - references/mapping-cheatsheet.md §8 now maps [assembly: Trait] to [assembly: TestCategory] / [assembly: TestProperty] instead of 'Remove'. - SKILL.md Step 12 promoted to 'Convert' (was 'Remove'); the same mapping is documented inline. - Notes after the Step 4 and §1 trait tables now disclose the assembly target so users do not assume class/method-only scope. Addresses PR feedback from @Evangelink. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address second round of PR review feedback From @Evangelink: - [Ignore]/[Timeout] do NOT discover a test on their own — they are modifiers. SKILL.md Step 4 + cheatsheet §1 now show [Fact(Skip)] -> [TestMethod] + [Ignore(...)] (and same for [Timeout]). Eval scenario 9 rubric updated to require both attributes. - TestProperty IS filterable (was incorrectly described as 'metadata that does not need filter integration'). Notes after the trait tables in both SKILL.md and cheatsheet §1 now show both filter syntaxes. - For environmental gates (OS-/CI-/arch-conditional), point at MSTest 3.10+'s condition attributes ([OSCondition], [CICondition], [ArchitectureCondition], [NonParallelizableCondition]) as the preferred alternative to overloading [TestCategory] or scattering Assert.Inconclusive through test bodies. Strengthened in cheatsheet §3.9, SKILL.md Step 6, Step 10 SkippableFact row, and the Common Pitfalls table. - TestDataRow<T> is also a supported MSTest data source (strongly typed with per-row DisplayName/Ignore metadata). Added to both SKILL.md Step 5 and cheatsheet §2 with link to the docs. - MSTest.Sdk + <UseVSTest>true</UseVSTest> pulls in Microsoft.NET.Test.Sdk automatically — the manual PackageReference was incorrect. Removed it from both files (Step 2, Step 3 'common mistakes', and Common Pitfalls). - Added the 'pin MSTest.Sdk in global.json msbuild-sdks' alternative as the recommended pattern for multi-project solutions. - Xunit.Combinatorial -> Combinatorial.MSTest (Youssef1313 community port). Updated both SKILL.md Step 10 and cheatsheet §10. From Copilot reviewer: - MSTest.Sdk example in SKILL.md Step 2 Option B hardcoded <TargetFramework>net9.0</TargetFramework>, contradicting the preserve-TFM rule. Replaced with a placeholder + explicit comment. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Improve xUnit-to-MSTest skill effectiveness based on eval feedback Eval results on PR #718 showed regressions on three rubric items where the agent did the migration correctly but did not COMMUNICATE the judgement-call decisions, so the judge could not verify the choice was deliberate: - ICollectionFixture scope decision (rubric: 'Explicitly explains the scope decision instead of silently widening' scored 1/5 because the agent said 'Let me convert everything' with zero scope discussion). Step 8 now requires a templated explanation of (source scope, target scope, what is shared, what is serialized, why the rejected alternative was rejected) before applying. - Parallelization 'MSTest default is serial' messaging (rubric scored 1.7/5 because the agent only implicitly conveyed it). Step 11 Choice A now demands a templated sentence explaining that the [assembly: Parallelize] is REQUIRED to match xUnit, otherwise the suite silently regresses to serial. - Response Guidelines now lists the three judgement-call decisions that MUST be communicated up-front: fixture scope, parallelization model, and the Throws/ThrowsExactly semantic flip. Additional fixes from this round: - Step 2: explicit guidance to default to Option A (MSTest metapackage) when the user says 'preserve VSTest', so the safer PackageReference path is picked over MSTest.Sdk + UseVSTest. - Step 4: pulled the '[Ignore]/[Timeout] are modifiers, need [TestMethod]' callout out of a table footer into a visible note above the table. - known-domains.txt: allowlist github.com/Youssef1313/Combinatorial.MSTest (referenced from SKILL.md Step 10 and cheatsheet §10 after the recent Xunit.Combinatorial -> Combinatorial.MSTest switch). Validator: green (24 skills, 11 agents). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add concrete TestContext.Current.CancellationToken migration example The CancellationToken scenario was failing/low-scoring because the skill only contained a one-line mapping with no concrete example. The agent often missed the requirement to: - Add constructor TestContext injection (even when ITestOutputHelper is absent) - Map Assert.False -> Assert.IsFalse alongside the rename - NOT fabricate a CancellationTokenSource as a replacement Add a full xUnit v3 -> MSTest worked example next to the TestContext.Current mapping (Step 9), and reinforce the CancellationTokenSource warning in the cheatsheet. The example covers all 3 rubric points for the scenario. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address third round of PR review feedback - Remove fictional MSTest condition attributes [ArchitectureCondition] and [NonParallelizableCondition] from SKILL.md and cheatsheet (only [OSCondition] and [CICondition] exist in MSTest 3.10+; for non-parallel intent use [DoNotParallelize], for architecture gating fall back to runtime Assert.Inconclusive). (Copilot) - TestPropertyAttribute targets only [Class|Method] (no AttributeTargets.Assembly), so [assembly: TestProperty(...)] does not compile. Update the trait notes in SKILL.md Step 4, cheatsheet section 1, Step 12, and cheatsheet section 8 to collapse a non-category xUnit [assembly: Trait] to [assembly: TestCategory] or push it down to per-class [TestProperty]. (@Evangelink) - Step 1 platform detection: stop inlining a buggy VSTest-vs-MTP matrix; delegate to the platform-detection skill. Note explicitly that <UseMicrosoftTestingPlatformRunner> only affects 'dotnet run' and is not a reliable runner signal. (@Youssef1313) - Step 2 Option A: add MTP code-coverage caveat -- Microsoft.NET.Test.Sdk pulls VSTest's Microsoft.CodeCoverage transitively, which can interfere with MTP's collector. Prefer Option B (MSTest.Sdk without UseVSTest) for MTP projects. (@Youssef1313) - Step 3: remove fictional MSBuild properties (<CaptureConsoleOutput>, <UseRoslynCompilers>); restate the bullet about xunit.runner.json -> Step 11 port instead. Restate the <UseMicrosoftTestingPlatformRunner> bullet to make clear it is not a runner switch. (@Youssef1313) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address Copilot review round 4 - mapping-cheatsheet.md (Assert.Contains predicate): the suggested fallback Assert.Contains(collection.First(x => predicate), collection) is buggy -- First() throws InvalidOperationException on no-match (changing the failure mode), and feeding the result back into Assert.Contains is circular. Keep only the correct translation: Assert.IsTrue(collection.Any(x => predicate)). - SKILL.md Step 4 / cheatsheet table: stop instructing 'mark every class sealed'. xUnit projects commonly use base/derived test classes (shared setup, generic base fixtures); mechanically sealing them would break compilation. Sealing is now framed as an optional follow-up handled by writing-mstest-tests, not part of the mechanical migration.

code-testing-agent: add polyglot pipeline examples for Python/TypeScript/Go/Java (#708)
* code-testing-agent: add polyglot pipeline examples for Python/TypeScript/Go/Java
The code-testing-agent skill family is polyglot in description but in
practice biased toward .NET because dotnet-examples.md was the only
filled-in pipeline walkthrough. The four sub-agents that participate in
the Research-Plan-Implement pipeline (researcher, planner, implementer,
generator) all pointed to dotnet-examples.md whenever they suggested a
concrete example, which made it harder for the agent to produce
idiomatic non-.NET tests (e.g. in msbench top5-* benchmarks for
Python/Flask, TypeScript/Express).
This change
* adds four new example files mirroring dotnet-examples.md format
(source → research → plan → generated test → fix cycle → final report):
- python-examples.md (pytest, unittest.mock, Mock(spec=...), parametrize)
- typescript-examples.md (Vitest with notes for Jest; it.each,
async tests, fake timers, ESM/CJS fix cycle)
- go-examples.md (standard testing package, table-driven subtests,
hand-written fake repository, injected clock)
- java-examples.md (JUnit 5 + Mockito on Maven, @ParameterizedTest +
@CsvSource, Clock.fixed, Surefire fix cycles)
* updates code-testing-extensions/SKILL.md TOC to list the new files
and clarifies usage instructions to read the matching <language>-
examples.md alongside the base extension
* makes the "Concrete example" pointers in code-testing-generator,
code-testing-implementer, code-testing-planner and
code-testing-researcher agents language-agnostic (list all available
example files instead of hard-coding dotnet-examples.md)
* expands code-testing-researcher project-structure detection list to
cover more Python (tox.ini, noxfile.py, requirements*.txt, uv.lock,
poetry.lock, pdm.lock), JS/TS (.mts/.cts/.jsx, vitest.config.*,
jest.config.*), C++ (CMakeLists.txt, BUILD.bazel, meson.build),
Java/Kotlin (pom.xml, build.gradle[.kts], wrappers), and other
ecosystem files; expands the Identify-Language section accordingly
* extends the "Language-Specific Examples" section in
code-testing-agent/SKILL.md to summarise each example file
Validated with: skill-validator check --plugin ./plugins/dotnet-test
(23 skills, 11 agents — all checks passed) and markdownlint-cli2.

* Address review feedback for #708
- go-examples.md: replace the hand-rolled `contains`/`stringIndex`
helpers with `strings.Contains` from the standard library. The hand-rolled
`contains` had subtly wrong semantics — `contains(""abc"", """")` returned
`false` while `strings.Contains` returns `true` — and the helpers are
unnecessary complexity for a code-generation example.
- go-examples.md: in the `go test -run` "wrong selection regex" sample fix
cycle, quote the test name and use `single_item` (matching the underscore
that the surrounding diagnosis text refers to) instead of the unquoted
`single item` which the shell would parse as two separate CLI arguments.
- java-examples.md: the source-tree file list described `Invoice.java` as a
`record` but the `InvoiceService.markAsPaid` example mutates the invoice
via `setStatus(...)` and `setPaidDate(...)` — records are immutable, so
the description was internally inconsistent. Re-describe it as a mutable
POJO with explicit mutators to match the service code.

Make dotnet-test analysis skills and auditor agent polyglot (#707)
* Make dotnet-test analysis skills and auditor agent polyglot Five test analysis skills and the test-quality-auditor agent in plugins/dotnet-test previously activated only on .NET MSTest/xUnit/NUnit/ TUnit cues, even though the underlying techniques (assertion diversity, anti-pattern detection, pseudo-mutation gap analysis, academic smell catalog, trait tagging) apply equally to other test frameworks. This change makes them polyglot across .NET, Python (pytest/unittest), TypeScript/JavaScript (Jest/Vitest/Mocha/node:test), Java (JUnit/TestNG), Go, Ruby (RSpec/Minitest), Rust, Swift (XCTest/Swift Testing), Kotlin (JUnit/Kotest), PowerShell (Pester), and C++ (GoogleTest/Catch2/doctest). Changes ------- * New reference skill `test-analysis-extensions` with per-language extension files (dotnet, python, typescript, java, go, ruby, rust, swift, kotlin, powershell, cpp). Each documents test markers, assertion APIs, sleep / time / random APIs, skip annotations, setup/teardown, mystery-guest indicators, integration markers, and tag-support capability for the corresponding framework. * `assertion-quality`, `test-anti-patterns`, `test-gap-analysis`, `test-smell-detection`, `test-tagging` SKILL.md updated: frontmatter now lists all polyglot frameworks (keeping .NET trigger words for backward compat); bodies reference `test-analysis-extensions` and add per-language calibration (e.g., Go/Rust table-driven loops are idiomatic and not Conditional Test Logic; pytest bare `assert` is canonical; missing-await on async assertions is a new Critical smell). * `test-quality-auditor` agent now runs language detection, gates .NET-only pipeline steps (coverage-analysis, CRAP, detect-static- dependencies, testability migration, experimental dotnet skills), and recommends native tooling for non-.NET projects via an explicit Capability Matrix. * README updated to split sections by polyglot vs .NET-only. * New polyglot eval scenarios added (Python/pytest, TS/Jest, Java/JUnit) alongside existing C# scenarios in `test-anti-patterns`, `assertion-quality`, `test-smell-detection`. The .NET-only skills (writing-mstest-tests, migrate-*, coverage-analysis, crap-score, detect-static-dependencies, run-tests, filter-syntax, platform-detection, dotnet-test-frameworks, mtp-hot-reload, exp-*) are unchanged and continue to activate only for .NET work. Validated with skill-validator `check --plugin ./plugins/dotnet-test`. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR #707 review feedback * typescript.md: replace xpect.fail() recommendation (Jest has no such API) with hrow new Error(...) / explicit failing assertion. * test-tagging SKILL.md description: clarify that unittest has no canonical tag syntax (pytest markers are the auto-edit mechanism; unittest is report-only). Switch doctest reference to "decorators" rather than implying a Catch2-style [tags] mechanism exists. * test-tagging SKILL.md auto-edit list and table: use `* doctest::test_suite("tag")` decorator chain syntax for doctest in both the bullet list and the per-framework table, matching the example already shown. * cpp.md extension: spell out the Catch2 vs doctest tagging distinction in the capability matrix (Catch2 [tag], doctest * doctest::test_suite("tag") decorator). Validated with `dotnet run --project eng/skill-validator/src -- check --plugin ./plugins/dotnet-test` (23 skills + 11 agents).

dotnet-test: add cross-language edit-boundary rules to code-testing-implementer (#689)
The code-testing-* agent family generates tests for 12 languages (not just .NET). Until now, no instruction told the implementer to keep its changes additive: it would routinely modify existing test files non-additively (deleting/reformatting lines) or edit non-test production code to make something easier to test. Both behaviors cause the change to be rejected by: - the msbench 'simple' test verifier (any 'dels > 0' on a test file, or any change to a non-test file, sets reward=0) - most real-world test-quality gates, code-review policies, and CI Add explicit cross-language rules in the implementer agent prompt: 1. Existing test files are append-only (no reformat/reorder/remove). 2. Do not modify non-test source files; surface untestable seams as follow-ups for the testability-migration agent. 3. Prefer new test files over edits to existing ones when equivalent. 4. Build-system manifests may be edited only for project/dependency registration. Rule 6 in the Rules section now points at the Step 4 detail so the implementer reads it on every phase. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

* Fix coverage-analysis activation for plateau diagnosis prompts coverage-analysis SKILL.md: - Trim verbose implementation details (provider detection, ReportGenerator) that consumed description budget without aiding skill activation - Add explicit USE FOR keywords: coverage stuck, coverage plateau, can't increase coverage, what's blocking coverage code-testing-agent SKILL.md: - Add 'diagnosing coverage plateaus or CRAP score computation (use coverage-analysis)' to DO NOT USE FOR boundary to prevent test-generation skill from intercepting diagnostic prompts * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * Strengthen code-testing-agent activation; harden coverage-analysis isolated mode Address eval regressions reported on PR #647 (run 25813728646): 1. code-testing-agent: `Generate tests for ContosoUniversity ASP.NET Core MVC app` was NOT ACTIVATED in plugin mode (detectedSkills=[], skillEventCount=0, invokedAgents=[]). The model bypassed the skill system entirely. - SKILL.md description: restructure to use the proven `Use when user says ...` pattern with quoted trigger phrases (matching the run-tests skill that consistently activates), make the link to the code-testing-generator sub-agent explicit, and tighten DO NOT USE FOR clauses. - eval prompt (eval.yaml + eval.vally.yaml): make the request pipeline-shaped (`project-wide, multi-file test generation task`, `scaffold a new test project`) so the model recognizes it as multi-step work that benefits from the orchestrated pipeline. Explicitly request coverlet.collector + a Cobertura XML run so rubric criterion 1 (`high line coverage as reported by the Cobertura XML in TestResults/`) becomes achievable without overfitting. 2. code-testing-tester agent + code-testing-extensions/dotnet.md: open a scoped exception to the `skip coverage tools` rule. Default behavior stays the same, but when the user/harness explicitly asks for a Cobertura/XML coverage artifact, the agent may add coverlet.collector to the generated test csproj so the harness's coverage command produces output. The agent still does not run the coverage command itself. 3. coverage-analysis SKILL.md: add a `User-visible output is mandatory` guard at the top of the Workflow section. The latest eval showed isolated mode producing literally `(no output)` in 2 of 3 scenarios — the agent ran Compute-CrapScores.ps1 / Extract-MethodCoverage.ps1 / ReportGenerator in parallel, then the session ended without ever surfacing findings. The guard tells the agent to always return a partial summary instead of ending silent, and to deprioritize ReportGenerator HTML when budget is tight. (Plugin-mode quality is already strong: 4.3 / 4.3 / 5.0 — no regression risk there.) Aggregate dotnet-test plugin description size: 14,925 chars (limit 15,000). skill-validator check passes (22 skills, 11 agents, 1 plugin); markdownlint passes for all 4 modified files. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Restore MSTest modernization exclusion in code-testing-agent description * Fix isolated-mode coverage-analysis: emit summary before optional ReportGenerator The previous workflow encouraged the agent to run `dotnet tool install` for ReportGenerator in parallel with the CRAP scoring scripts (Phase 2 "Steps 3 and 4 in parallel" + Phase 3 "Steps 5 and 6 in parallel"). In isolated mode that pattern reliably crashed the session with "Failed to persist session events: timeout while waiting for mutex to become available" right after the scripts returned valid data, so the agent never produced the user-facing summary. Restructure the workflow into 5 phases: - Phase 1 (Setup) - unchanged - Phase 2 (Test execution) - skip when Cobertura XML already exists - Phase 3 (Analysis) - run only the two PowerShell scripts, no RG - Phase 4 (User-facing summary) - MANDATORY, must be the next assistant response after Phase 3, before any RG work; also save coverage-analysis.md as a secondary follow-up - Phase 5 (ReportGenerator HTML/CSV) - strictly optional, post-summary, skipped by default for existing-Cobertura and plateau-diagnosis paths Also update references/output-format.md so the Reports section marks RG artifacts as "Not generated (optional - request HTML reports to enable)" when Phase 5 has not run, and update references/guidelines.md so the "show and open the markdown report" rule explicitly defers to the user-facing assistant response. Targets the isolated-mode regressions in PR #647 eval: - Project-wide coverage with existing Cobertura: 1.0/5 -> expected 3+ - Coverage plateau diagnosis: 1.0/5 -> expected 3+ - Run coverage from scratch: 2.3/5 -> expected steady or up Verified: skill-validator check --plugin ./plugins/dotnet-test passes; markdownlint-cli2 clean on all 3 modified files. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR #647 review comments 1. Prerequisites: distinguish the from-scratch path (needs NuGet for the coverage-provider package install + optional internet for ReportGenerator) from the existing-Cobertura path (needs neither). 2. Add Step 2c "Discover or accept existing Cobertura XML" so the existing-data path actually has $coberturaFiles populated before Phase 3, instead of relying on Phase 2's discovery (which it skips). Also clarify Step 2's destructive Remove-Item only manages the skill-owned coverage-analysis/ subdirectory. 3. references/output-format.md: replace the unconditional "Reports saved to: <coverageDir>/reports/" line with one that always points at <coverageDir>/ (markdown summary + raw Cobertura) and only mentions reports/ if Phase 5 ran. 4. Have Compute-CrapScores.ps1 emit OVERALL_LINE_COVERAGE and OVERALL_BRANCH_COVERAGE from the Cobertura root attributes, and update Phase 4 to read those values directly from the script's output. The Phase 4 mandatory-summary rule no longer requires a separate XML parse before composing the response. Verified: skill-validator check --plugin ./plugins/dotnet-test passes; markdownlint-cli2 clean on all modified files; Compute-CrapScores.ps1 smoke-tested on a synthetic Cobertura XML (emits OVERALL_LINE_COVERAGE:75, OVERALL_BRANCH_COVERAGE:50 alongside HOTSPOTS).

Promote 4 experimental test skills to dotnet-test plugin (#634)
Move assertion-quality, test-gap-analysis, test-smell-detection, and test-tagging from dotnet-experimental to dotnet-test. These skills have demonstrated sufficient eval coverage, unique value beyond baseline model capabilities, and are already integrated into the test-quality-auditor agent pipeline. Changes: - Move skills and tests, dropping the exp- prefix - Update all cross-references in skill descriptions and routing tables - Update test-quality-auditor agent and eval scenarios - Update CODEOWNERS for the moved paths - Delete duplicate exp-dotnet-test-frameworks (identical to dotnet-test-frameworks) - Fix stale exp-dotnet-test-frameworks reference in exp-test-maintainability Skills held back for further iteration: - exp-mock-usage-analysis: baseline model scores 5/5 on key scenarios - exp-test-maintainability: quality gains offset by token overhead |

Improve test generation quality based on SWE Atlas benchmark analysis (#599)
* Improve test quality for benchmark performance Based on SWE Atlas benchmark analysis (48.8% vanilla vs 19-34% CTA): 1. Default to Direct strategy for single-task requests — reduces multi-agent overhead that costs tokens without improving results 2. Run tests immediately in Direct strategy — catches assertion errors early instead of accumulating failures 3. Read source thoroughly before writing tests — trace actual logic and return values, not just function signatures 4. Quality over Quantity guidelines — cover stated requirements first, fewer focused tests beat many shallow ones 5. Verify tests are implementation-specific — tests that pass with an empty function body aren't testing anything useful Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Combine redundant implementation-specificity bullets into one Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

Add concrete pipeline examples for code-testing-agent (#572)
Add end-to-end input/output examples to anchor expected behavior for the LLM, addressing the Example Quality (2/5) review feedback. Changes: - New extensions/dotnet-examples.md with .NET-specific examples: sample source code, research output, plan output, generated test file, fix cycle walkthroughs, and final report - SKILL.md: replace one-liner examples with strategy selection table, pipeline walkthrough, and pointer to language-specific extensions - Generator agent: add strategy decision examples and sample final report - Researcher/Planner/Implementer agents: add references to extension examples for concrete output shapes Architecture keeps core agents language-agnostic — all language-specific examples live in the extensions/ folder. |

Ensure validation runs for all strategies including Direct (#570)
Harden the test generator agent to ensure final build validation, test validation, and git commit always run — even when using the Direct strategy for small requests. Changes: - Step 1: Mandate reading language-specific extensions (e.g., dotnet.md) before writing any code. The extension contains critical project registration (dotnet sln add) and build validation guidance. - Step 2: Direct strategy now skips only Steps 3-5 (research, plan, implement sub-agents), NOT Steps 6-9. Added explicit note that Steps 6-9 are mandatory for ALL strategies. - Step 6: Clarify full-solution build must use no --framework flag to catch multi-target framework issues (e.g., net472 errors). - Step 7: Require fresh build for final test validation (no --no-build). - New Step 9: Explicit git commit with verification that the diff is non-empty. - New rules 9-11: Read extensions first, always validate+commit, preserve existing tests. Motivated by MSBench investigation showing: - Agent used Direct strategy and skipped final validation entirely - Agent never read extensions/dotnet.md (missing dotnet sln add) - Agent forgot to git commit (300 tests created, Changes +0 -0) - Agent deleted pre-existing tests while adding new ones Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |

Fix test-anti-patterns plugin activation by disambiguating competing descriptions (#552)
The test-anti-patterns skill was not reliably activated in plugin mode because sibling descriptions overlapped: - test-quality-auditor agent: narrowed to multi-skill audit pipelines only, explicitly excluding single-file reviews - writing-mstest-tests skill: removed 'review' and 'anti-patterns' from description, added explicit exclusion for test quality auditing - test-anti-patterns skill: expanded trigger phrases to better match review prompts (flaky tests, duplication, tests that pass without verifying) |

Add test-quality-auditor hub agent for .NET test suite analysis (#541)
* Add test-quality-auditor hub agent for .NET test suite analysis Introduces a new test-quality-auditor agent that triages test quality concerns to specialized analysis skills: assertion quality, test smells, anti-patterns, mock usage, test gaps, maintainability, coverage risk, and test tagging. Includes a comprehensive audit pipeline that chains multiple skills for broad health checks. * Address Copilot review: clarify diagnostic role and coverage routing - Reword intro to acknowledge file-modifying workflows (test tagging) are only used with explicit user confirmation - Clarify coverage-analysis vs crap-score: prefer coverage-analysis for project-wide analysis, reserve crap-score for targeted method/class scope |

Add test-migration hub agent for .NET test framework and platform migrations (#540)
* Add test-migration hub agent for .NET test framework and platform migrations Introduces a new test-migration agent that auto-detects the current test framework, version, and platform, then routes to the appropriate migration skill (MSTest v1/v2→v3, v3→v4, xUnit v2→v3, VSTest→MTP). Handles multi-step migrations with commit boundaries between steps. * Align framework detection with platform-detection skill Address Copilot review: MSTest requires metapackage, Sdk, or both TestFramework+TestAdapter (not either alone). Add missing xUnit MTP package variants. |

Add testability migration skills and agent for dotnet-test (#518)
* Add testability migration skills and agent for dotnet-test Introduces three skills and one orchestrator agent to help developers incrementally replace hard-to-test static dependencies with injectable abstractions: - detect-static-dependencies: scans C# code for DateTime.Now, File.*, Environment.*, HttpClient, Console.*, Process.* and ranks by frequency - generate-testability-wrappers: generates wrapper interfaces or guides adoption of built-in abstractions (TimeProvider, IHttpClientFactory, System.IO.Abstractions) - migrate-static-to-wrapper: mechanical codemod-style bulk replacement of static call sites with wrapper calls, scoped per project/namespace - testability-migration agent: orchestrates the Detect-Generate-Migrate pipeline end-to-end Includes eval.yaml tests and fixture projects for all three skills and the agent. * Fix activation, token overhead, and eval timeouts - Expand skill descriptions with more trigger phrases for migrate-static-to-wrapper and generate-testability-wrappers to fix NOT ACTIVATED issues - Collapse verbose replacement mapping tables and constructor examples to reduce token overhead (~30% fewer tokens) - Increase generate-testability-wrappers eval timeouts from 120s to 240s to prevent timeout-impacted scoring - Soften detect-static-dependencies scenario 2 rubric to reduce run-to-run variance in plugin mode - Increase migrate-static-to-wrapper non-activation timeout |
