Use when receiving an ambiguous feature request, when scope is unclear, or before writing any plan
Use after verification-before-completion passes and code review is clean, to close out the development branch
Use after writing a plan document in docs/plans/, before requesting user confirmation
Use when receiving feedback from code-reviewer subagent or human reviewer
Use when a feature, bugfix, or refactoring step is completed and needs review, or before merging to main, or when user says "review", "审查", "帮我看看代码"
Use when executing an implementation plan with 3+ independent tasks in the current session

在 SDK 核心路径上，先写会失败的测试，再写通过测试的最小实现。
核心原则： 测试先行 = 接口先行。想不出怎么测，通常是接口设计有问题。
循环节奏： 红 → 绿 → 重构，单次循环 ≤ 10 分钟。

所有测试源码最终都编译进 GrowingAnalyticsTests 这个 Xcode target（不是每个子目录一个 target）。运行时按 GrowingAnalyticsTests.xctestplan 调度，靠 -only-testing: 过滤子集。

事件从 track: 调用到入库是异步链路（后台 GCD 队列）。测试时：
XCTestExpectation + waitForExpectations:tearDown 必须重置会被当前 case 污染到的全局状态：SDK 单例、事件数据库、配置缓存等。SDK 本身不暴露统一的 reset API，具体策略看对象类型：
[GrowingHybridModule.sharedInstance resetBridgeSettings]Example/GrowingAnalyticsTests/Helper/ 下测试辅助创建的数据库文件GrowingConfigurationManager 重新 setConfigurationMockEventQueue、InvocationHelper- (void)tearDown {
// 按本 case 涉及的副作用逐个还原；禁止留空 tearDown
[super tearDown];
}
任何采集路径都必须有"关闭总开关后不采集"的测试。
| Excuse | Reality |
|---|---|
| "先写实现再补测试" | 测试退化为"验证代码写了什么" |
| "这块改动太简单不用测试" | 核心路径零例外 |
| "测试第一次就绿了" | 没见过 Red 的 Green 不可信 |
| "dataCollectionEnabled=false 的路径不用测" | 这是隐私合规红线 |
