# 使用覆盖测试依赖项 { #testing-dependencies-with-overrides }

## 测试时覆盖依赖项 { #overriding-dependencies-during-testing }

有些场景下，您可能需要在测试时覆盖依赖项。

即不希望运行原有依赖项（及其子依赖项）。

反之，要在测试期间（或只是为某些特定测试）提供只用于测试的依赖项，并使用此依赖项的值替换原有依赖项的值。

### 用例：外部服务 { #use-cases-external-service }

常见实例是调用外部第三方身份验证应用。

向第三方应用发送令牌，然后返回经验证的用户。

但第三方服务商处理每次请求都可能会收费，并且耗时通常也比调用写死的模拟测试用户更长。

一般只要测试一次外部验证应用就够了，不必每次测试都去调用。

此时，最好覆盖调用外部验证应用的依赖项，使用返回模拟测试用户的自定义依赖项就可以了。
