Давайте рассмотрим, как мы можем это реализовать.

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

  static void clear(Buffer b) {
    b.clear();
  }

  static void flip(Buffer b) {
    b.flip();
  }

  static void limit(Buffer b, int limit) {
    b.limit(limit);
  }

  static void mark(Buffer b) {
    b.mark();
  }

  static void position(Buffer b, int position) {
    b.position(position);
  }

  static void reset(Buffer b) {
    b.reset();
  }

  private Java8Compatibility() {}

    f.write_text("foo")
    return f


@pytest.fixture
def tmp_file_2(tmp_path: Path) -> Path:
    f = tmp_path / "example2.txt"
    f.write_text("bar")
    return f


@pytest.mark.parametrize("endpoint_path", ("/file_before_form", "/file_after_form"))
def test_file_form_order(endpoint_path: str, tmp_file_1: Path):
    response = client.post(
        url=endpoint_path,

你已經看過如何使用提供的 `TestClient` 來測試你的 FastAPI 應用。到目前為止，你只看到如何撰寫同步測試，沒有使用 `async` 函式。

在測試中能使用非同步函式會很有用，例如當你以非同步方式查詢資料庫時。想像你想測試發送請求到 FastAPI 應用，然後在使用非同步資料庫函式庫時，驗證後端是否成功把正確資料寫入資料庫。

來看看怎麼做。

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

若要在測試中呼叫非同步函式，測試函式本身也必須是非同步的。AnyIO 為此提供了一個好用的外掛，讓我們可以標示某些測試函式以非同步方式執行。

## HTTPX { #httpx }

即使你的 FastAPI 應用使用一般的 `def` 函式而非 `async def`，它在底層仍然是個 `async` 應用。

Schauen wir uns an, wie wir das machen können.

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

Let's look at how we can make that work.

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

     * @return true if completed, false otherwise
     */
    public boolean isCompleted() {
        return completed;
    }

    /**
     * Mark request as completed
     */
    public void markCompleted() {
        this.completed = true;
    }

    /**
     * Mark request as failed with error
     *
     * @param error exception that caused the failure
     */
    public void markFailed(Exception error) {
