**FastAPI** 提供了和 `starlette.testclient` 一样的 `fastapi.testclient`，只是为了方便开发者。但它直接来自Starlette。

///

/// tip | "提示"

除了发送请求之外，如果你还想测试时在FastAPI应用中调用 `async` 函数（例如异步数据库函数）， 可以在高级教程中看下 [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} 。

## 分离测试

在实际应用中，你可能会把你的测试放在另一个文件里。

您的**FastAPI**应用程序也可能由一些文件/模块组成等等。

Native Image Tests
==================

This executes OkHttp's test suite inside a Graalvm image.

Build the Native Image
----------------------

Compile the classes and metadata into a Graalvm native image.

```
./gradlew --info native-image-tests:nativeImage
```

Execute
-------

The native image runs JUnit 5 tests in the project.

```
./native-image-tests/build/graal/ConsoleLauncher
