让我们看看如何才能实现这一点。

## pytest.mark.anyio { #pytest-mark-anyio }

如果我们想在测试中调用异步函数，那么我们的测试函数必须是异步的。 AnyIO 为此提供了一个简洁的插件，它允许我们指定一些测试函数要异步调用。

## HTTPX { #httpx }

即使您的 **FastAPI** 应用程序使用普通的 `def` 函数而不是 `async def` ，它本质上仍是一个 `async` 异步应用程序。

`TestClient` 在内部通过一些“魔法”操作，使得您可以在普通的 `def` 测试函数中调用异步的 FastAPI 应用程序，并使用标准的 pytest。但当我们在异步函数中使用它时，这种“魔法”就不再生效了。由于测试以异步方式运行，我们无法在测试函数中继续使用 `TestClient`。

    private byte[] bytes;

    AppendableByteSource(byte[] initialBytes) {
      this.bytes = initialBytes.clone();
    }

    @Override
    public InputStream openStream() {
      return new In();
    }

    void append(byte[] b) {
      byte[] newBytes = Arrays.copyOf(bytes, bytes.length + b.length);
      System.arraycopy(b, 0, newBytes, bytes.length, b.length);
      bytes = newBytes;
