Michał Pierzchała 5d10ced2b5 perf(ios): add lifecycle-safe runner sequence command for hot press series
Adds a narrow 'sequence' runner command that batches an explicit
allowlist of coordinate steps (tap, longPress, drag) into one
lifecycle-tracked request with stop-on-first-failure and small bounded
per-step results. iOS press series with hold/jitter now issue one
sequence request per ~20-step chunk (also budgeted to stay under the
runner's 30s main-thread watchdog) instead of one request per press.
Sequence responses are journaled and retained, so lost-response recovery
returns observed results without replaying the gesture sequence.

agent-device iOS Runner

This folder contains the lightweight XCUITest runner used to provide element-level automation for Apple-family targets.

Intent

  • Provide a minimal XCTest target that exposes UI automation over a small HTTP server.
  • Allow local builds via xcodebuild and caching for faster subsequent runs.
  • Support simulator prebuilds where compatible.

Status

Current internal runner for iOS, tvOS, and macOS desktop automation.

UITest Runner File Map

AgentDeviceRunnerUITests/RunnerTests is split into focused files to reduce context size for contributors and LLM agents.

  • RunnerTests.swift: shared state/constants, setUp(), and testCommand() entry flow.
  • RunnerTests+Models.swift: wire protocol models (Command, Response, snapshot payload models).
  • RunnerTests+Environment.swift: environment and CLI argument helpers (RunnerEnv).
  • RunnerTests+Transport.swift: TCP request handling and HTTP parsing/encoding.
  • RunnerTests+CommandExecution.swift: command dispatch (execute*) and command switch.
  • RunnerTests+Lifecycle.swift: activation/retry/stabilization and recording lifecycle helpers.
  • RunnerTests+Interaction.swift: tap/drag/swipe/type/back/home/rotate/app-switcher helpers.
  • RunnerTests+Snapshot.swift: fast/raw snapshot builders and include/filter helpers.
  • RunnerTests+SystemModal.swift: SpringBoard/system modal detection and modal snapshot shaping.
  • RunnerTests+ScreenRecorder.swift: nested ScreenRecorder implementation.

Snapshot Strategy

iOS snapshots have two explicit capture modes:

  • full/raw snapshots use recursive XCTest snapshots for rich hierarchy and diagnostics;
  • compact interactive snapshots use a bounded flat XCTest query path for fast agent-facing refs.

Some simulator apps expose accessibility trees that lower-level AX services can inspect but XCTest cannot serialize reliably. In those cases compact interactive snapshots may return a sparse root quickly, while full snapshots preserve the XCTest error. See ../docs/adr/0004-ios-snapshot-backend-strategy.md for the backend boundary and the rationale for a future simulator AX-service backend.

Protocol Notes

  • The daemon posts JSON commands to POST /command on the runner's local HTTP listener.
  • The runner responds with a JSON envelope shaped as { ok, data?, error? }.
  • The protocol is internal to agent-device; when adding or renaming commands, update both wire models and the protocol tests/docs in the same change.
