/// tip

If you want to **learn FastAPI** in a structured way (recommended), go and read the [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} chapter by chapter instead.

	logger.Trace(context.Background(), time.Now(), func() (string, int64) {
		return "select count(*) from users", 0
	}, nil)

	if strings.Contains(buf.String(), "gorm/logger/slog.go") {
		t.Error("Found internal slog.go reference in caller frame. Expected only test file references.")
	}

	if !strings.Contains(buf.String(), "gorm/logger/slog_test.go") {

import org.apache.maven.execution.MavenSession;
import org.apache.maven.execution.scope.internal.MojoExecutionScope;
import org.apache.maven.impl.DefaultToolchainManager;
import org.apache.maven.impl.InternalSession;
import org.apache.maven.impl.resolver.MavenSessionBuilderSupplier;
import org.apache.maven.rtinfo.RuntimeInformation;
import org.apache.maven.session.scope.internal.SessionScope;
import org.codehaus.plexus.PlexusContainer;

/// 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。

### **FastAPI** app 文件

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

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

Как вы видели в предыдущей главе о [Концепциях деплоя](concepts.md){.internal-link target=_blank}, существует несколько стратегий.

Здесь я покажу, как использовать **Uvicorn** с **воркер-процессами** через команду `fastapi` или напрямую через команду `uvicorn`.
