Summary

  • Migrate @web/test-runner-junit-reporter tests from mocha/chai to node:test + node:assert/strict
  • 1 TS file, needs Chrome, XML snapshot comparison
  • import type { TestRunnerCoreConfig } (type-only)
  • Rename test to test:node
  • --experimental-strip-types for CI compat

Test plan

  • 3/3 tests pass on Node 22.22.3 with Chrome + NODE_OPTIONS='--no-experimental-strip-types'
  • ESLint clean
  • Prettier clean
  • Code review clean

Replace mocha globals and chai assertions with node:test and
node:assert/strict. Rename `test` to `test:node`.

- `import type { TestRunnerCoreConfig }` (type-only)
- `../src/junitReporter.js` -> `../dist/junitReporter.js`
- `__dirname` -> `import.meta.dirname`
- `expect(actual).to.equal(expected)` -> `assert.equal(actual, expected)`
- `function()` -> arrow functions
- Add `--experimental-strip-types` for CI compat

npm workspaces run test scripts from the package directory, not the
repo root. The test runner computes file paths relative to cwd, so
XML output paths are now relative to the package root (test/fixtures/...)
instead of the repo root (packages/test-runner-junit-reporter/test/...).

Updated expected XML snapshots to match.
