test

作者： facebook

在React程式碼庫中跨多個發行通道與配置執行測試。支援六個發行通道：source（預設）、experimental、www、www with variant false、stable 與 classic，各自具有不同的功能旗標配置。接受測試模式、TDD 的監控模式，以及用於測試不同程式碼路徑的變體旗標。需要明確的測試模式參數以避免執行整個測試套件；使用 --silent 旗標來顯示失敗資訊，並使用 --no-watchman 進行沙箱隔離...

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.
