---name: testdescription: Use when you need to run tests for React core. Supports source, www, stable, and experimental channels.--- Run tests for the React codebase. Arguments:- $ARGUMENTS: Channel, flags, and test pattern Usage Examples:- `/test ReactFiberHooks` - Run with source channel (default)- `/test experimental ReactFiberHooks` - Run with experimental channel- `/test www ReactFiberHooks` - Run with www-modern channel- `/test www variant false ReactFiberHooks` - Test __VARIANT__=false- `/test stable ReactFiberHooks` - Run with stable channel- `/test classic ReactFiberHooks` - Run with www-classic channel- `/test watch ReactFiberHooks` - Run in watch mode (TDD) Release Channels:- `(default)` - Source/canary channel, uses ReactFeatureFlags.js defaults- `experimental` - Source/experimental channel with __EXPERIMENTAL__ flags = true- `www` - www-modern channel with __VARIANT__ flags = true- `www variant false` - www channel with __VARIANT__ flags = false- `stable` - What ships to npm- `classic` - Legacy www-classic (rarely needed) Instructions:1. Parse channel from arguments (default: source)2. Map to yarn command:   - (default) → `yarn test --silent --no-watchman <pattern>`   - experimental → `yarn test -r=experimental --silent --no-watchman <pattern>`   - stable → `yarn test-stable --silent --no-watchman <pattern>`   - classic → `yarn test-classic --silent --no-watchman <pattern>`   - www → `yarn test-www --silent --no-watchman <pattern>`   - www variant false → `yarn test-www --variant=false --silent --no-watchman <pattern>`3. Report test results and any failures Hard Rules:1. **Use --silent to see failures** - This limits the test output to only failures.2. **Use --no-watchman** - This is a common failure in sandboxing. Common Mistakes:- **Running without a pattern** - Runs ALL tests, very slow. Always specify a pattern.- **Forgetting both www variants** - Test `www` AND `www variant false` for `__VARIANT__` flags.- **Test skipped unexpectedly** - Check for `@gate` pragma; see `feature-flags` skill.
