## Tests

Es gibt ein Skript, das Sie lokal ausführen können, um den gesamten Code zu testen und Code Coverage Reporte in HTML zu generieren:

<div class="termy">

```console
$ bash scripts/test-cov-html.sh
```

</div>

                absl::Span<AbstractTensorHandle* const> inputs,
                absl::Span<AbstractTensorHandle*> outputs, bool use_function) {
  if (use_function) {
    const char* fn_name = "test_fn";
    core::RefCountPtr<AbstractFunction> scoped_func;
    // Returning null tensors from a tf.function is not supported, so we keep
    // track of indices in the model's outputs are nullptr in this set.

* Durch die Verwendung einer Abhängigkeit können Sie das Testen vereinfachen.
* Sie können `.env`-Dateien damit verwenden.

	return obj
}

// SyncAll simulates the controller periodic sync of volumes and claim. It
// simply adds all these objects to the internal queue of updates. This method
// should be used when the test manually calls syncClaim/syncVolume. Test that
// use real controller loop (ctrl.Run()) will get periodic sync automatically.
func (r *VolumeReactor) SyncAll() {
	r.lock.Lock()
	defer r.lock.Unlock()

	for _, c := range r.claims {

}

func (t *Tester) ClusterScope() *Tester {
	t.tester = t.tester.ClusterScope()
	return t
}

func (t *Tester) Namer(namer func(int) string) *Tester {
	t.tester = t.tester.Namer(namer)
	return t
}

func (t *Tester) AllowCreateOnUpdate() *Tester {
	t.tester = t.tester.AllowCreateOnUpdate()
	return t
}

func (t *Tester) GeneratesName() *Tester {
	t.tester = t.tester.GeneratesName()
	return t
}

    **FastAPI** 提供了和 `starlette.testclient` 一样的 `fastapi.testclient`，只是为了方便开发者。但它直接来自Starlette。

!!! 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。
