`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`。

`TestClient` 是基于 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> 的。幸运的是，我们可以直接使用它来测试API。

## 示例

            Class<? extends RESULT> entityType, CursorSelectOption option) {
        delegateSelectCursor(cb, handler, entityType);
    }

    @Override
    protected <RESULT extends ENTITY> void delegateSelectCursor(final ConditionBean cb, final EntityRowHandler<RESULT> handler,
            final Class<? extends RESULT> entityType) {
        delegateBulkRequest(cb, searchHits -> {

  @WeakOuter
  private final class IsStartableGuard extends Guard {
    IsStartableGuard() {
      super(AbstractService.this.monitor);
    }

    @Override
    public boolean isSatisfied() {
      return state() == NEW;
    }
  }

  private final Guard isStoppable = new IsStoppableGuard();

  @WeakOuter
  private final class IsStoppableGuard extends Guard {
    IsStoppableGuard() {
