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.

为React代码库运行测试。

参数：

$ARGUMENTS：渠道、标志和测试模式

使用示例：

```
/test ReactFiberHooks
```
- 使用source渠道运行（默认）
```
/test experimental ReactFiberHooks
```
- 使用experimental渠道运行
```
/test www ReactFiberHooks
```
- 使用www-modern渠道运行
```
/test www variant false ReactFiberHooks
```
- 测试__VARIANT__=false
```
/test stable ReactFiberHooks
```
- 使用stable渠道运行
```
/test classic ReactFiberHooks
```
- 使用www-classic渠道运行
```
/test watch ReactFiberHooks
```
- 以监听模式运行（TDD）

发布渠道：

```
(default)
```
- Source/canary渠道，使用ReactFeatureFlags.js的默认设置
```
experimental
```
- Source/experimental渠道，__EXPERIMENTAL__标志设为true
```
www
```
- www-modern渠道，__VARIANT__标志设为true
```
www variant false
```
- www渠道，__VARIANT__标志设为false
```
stable
```
- 发布至npm的版本
```
classic
```
- 遗留的www-classic（很少需要）

操作步骤：

从参数中解析渠道（默认：source）

映射为yarn命令：
