## 分離測試 { #separating-tests }

在真實專案中，你大概會把測試放在不同的檔案中。

你的 **FastAPI** 應用也可能由多個檔案/模組組成，等等。

### **FastAPI** 應用檔案 { #fastapi-app-file }

假設你的檔案結構如[更大型的應用](bigger-applications.md)所述：

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

在 `main.py` 檔案中有你的 **FastAPI** 應用：


{* ../../docs_src/app_testing/app_a_py310/main.py *}

///

## 分离测试 { #separating-tests }

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。

### **FastAPI** app 文件 { #fastapi-app-file }

假设你有一个像[更大的应用](bigger-applications.md)中所描述的文件结构:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

在 `main.py` 文件中你有一个 **FastAPI** app:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

## Configuraciones en otro módulo { #settings-in-another-module }

Podrías poner esas configuraciones en otro archivo de módulo como viste en [Aplicaciones Más Grandes - Múltiples Archivos](../tutorial/bigger-applications.md).

Por ejemplo, podrías tener un archivo `config.py` con:

{* ../../docs_src/settings/app01_py310/config.py *}

Y luego usarlo en un archivo `main.py`:

    // This may be mutated by releaseConnectionNoEvents()!
    val candidate = call.connection ?: return null

    // Make sure this connection is healthy & eligible for new exchanges. If it's no longer needed
    // then we're on the hook to close it.
    val healthy = candidate.isHealthy(doExtensiveHealthChecks)
    var noNewExchangesEvent = false
    val toClose: Socket? =
      candidate.withLock {
        when {

      if (name != null) path.removeAt(path.size - 1)
    }
  }

  /**
   * Execute [block] with a new namespace for type hints. Type hints from the enclosing type are no
   * longer usable by the current type's members.
   */
  fun <T> withTypeHint(block: () -> T): T {
    typeHintStack.add(null)
    try {
      return block()
    } finally {
