Вы можете узнать больше подробностей в статье [Запуск lifespan в тестах на официальном сайте документации Starlette.](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

Для устаревших событий `startup` и `shutdown` вы можете использовать `TestClient` следующим образом:

import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.mockito.Mock;

/**
 * Test class for CloseableIterator interface functionality
 */
@DisplayName("CloseableIterator Tests")
class CloseableIteratorTest extends BaseTest {

    @Mock
    private CloseableIterator<SmbResource> mockIterator;

    @Test
    @DisplayName("Should define close method")

MockWebServer for JUnit 4
=========================

This module integrates mockwebserver3.MockWebServer with JUnit 4.

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit4:5.3.0")
```

Then in tests annotated `@org.junit.Test`, you may declare a field with the `@Rule` annotation:

```
@Rule public final MockWebServerRule serverRule = new MockWebServerRule();
```

# Increase the V8 stack size from the default of 984K
# to 8192K to ensure all tests can pass without hitting
# stack size limits.

**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。

- Favour a working external library if appropriate.  There are many examples of OkHttp libraries that can sit on top or hook in via existing APIs.
- Get working code on a personal branch with tests before you submit a PR.
- OkHttp is a small and light dependency.  Don't introduce new dependencies or major new functionality.
