## Summary `oxc_react_compiler` had no committed test over the upstream React Compiler fixture corpus — the fixtures lived only in the `oxc-project/forked-react-compiler` checkout, exercised out-of-tree. That gap let real regressions slip past the 15 in-crate integration tests. This PR closes it. - **`crates/oxc_react_compiler/fixtures/`** — 1734 fixture *input* files (`.js`/`.ts`/`.tsx`/`.jsx`/`.mjs`), copied from the fork's `babel-plugin-react-compiler/src/__tests__/fixtures/compiler` tree with subdirectories preserved. Flow fixtures (the `@flow`-pragma ones) are excluded — oxc has no Flow parser. The upstream `.expect.md` goldens are also not copied; insta is the golden here. - **`crates/oxc_react_compiler/tests/snapshot.rs`** — an `insta::glob!` test that, per fixture, derives `PluginOptions`/`EnvironmentConfig` from the first-line `// @directive` pragmas (base `compilationMode=all` / `panicThreshold=all_errors`, matching the upstream `snap` runner), parses → builds semantic → runs `transform`, and snapshots the compiled output plus diagnostics. Unrecognised directives are ignored, as upstream does; camelCase flag directives map to `EnvironmentConfig` fields via `convert_case`. - **`crates/oxc_react_compiler/tests/snapshots/`** — 1734 committed `.snap` goldens (oxc's own output). - **`.typos.toml`** — excludes the fixtures dir (the upstream fixtures contain intentional typos; `**/*.snap` was already excluded). These snapshots are oxc's own golden output, so `cargo test` (and CI) now catches any change in compiler behaviour across the corpus. Regenerate after an intended change with `cargo insta accept`. ## Verification - `cargo test -p oxc_react_compiler` passes — the 1734-fixture snapshot test plus the existing 15 integration tests; also green under `--all-features` (matches the cross-target CI job). - clippy `-D warnings`, `cargo fmt`, and `typos` clean. - No fixture panics; 1336 compiled / 398 unchanged / 335 with diagnostics. - The `error.*` fixtures capture the exact diagnostics — including the "Cannot reassign variable after render" error that a recent scoping change had silently suppressed, confirming the suite catches real regressions. --- AI usage disclosure: authored with Claude Code and reviewed before submission. 🤖 Generated with [Claude Code](https://claude.com/claude-code)
