test

작성자: facebook

React 코드베이스의 여러 릴리스 채널과 설정에서 테스트를 실행합니다. source(기본값), experimental, www, variant false가 적용된 www, stable, classic의 여섯 가지 릴리스 채널을 지원하며, 각 채널은 고유한 기능 플래그 구성을 가집니다. 테스트 패턴, TDD를 위한 감시 모드, 다양한 코드 경로를 테스트하기 위한 variant 플래그를 허용합니다. 전체 테스트 스위트 실행을 방지하기 위해 명시적인 테스트 패턴 인수가 필요하며, 실패를 표면화하기 위해 --silent 플래그를 사용하고 샌드박싱을 위해 --no-watchman을 사용합니다...

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:

Parse channel from arguments (default: source)
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>
Report test results and any failures

Hard Rules:

Use --silent to see failures - This limits the test output to only failures.
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.
