您已经了解了如何使用 `TestClient` 测试 **FastAPI** 应用程序。但是到目前为止，您只了解了如何编写同步测试，而没有使用 `async` 异步函数。

在测试中能够使用异步函数可能会很有用，比如当您需要异步查询数据库的时候。想象一下，您想要测试向 FastAPI 应用程序发送请求，然后验证您的后端是否成功在数据库中写入了正确的数据，与此同时您使用了异步的数据库的库。

让我们看看如何才能实现这一点。

## 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

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。

        assertFalse(searchRenderData.isExistNextPage());

        // Test with true
        searchRenderData.setExistNextPage(true);
        assertTrue(searchRenderData.isExistNextPage());

        // Toggle back to false
        searchRenderData.setExistNextPage(false);
        assertFalse(searchRenderData.isExistNextPage());
    }

    public void test_setAndIsExistPrevPage() {
        // Test with false

        // The sessionSetup method would normally send authentication messages
        // Only mark the sessionSetup response as received, not the actual request/response

            ServerMessageBlock request = invocation.getArgument(0);
            ServerMessageBlock response = invocation.getArgument(1);
            // Only mark session setup responses as received, not our test request

### Environment variables

#### MINIO_ETCD_ENDPOINTS

This is comma separated list of etcd servers that you want to use as the MinIO federation back-end. This should
be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

#### MINIO_DOMAIN

This is the top level domain name used for the federated setup. This domain name should ideally resolve to a load-balancer
