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.
