And all of them can use `yield`.

In this case `dependency_c`, to execute its exit code, needs the value from `dependency_b` (here named `dep_b`) to still be available.

And, in turn, `dependency_b` needs the value from `dependency_a` (here named `dep_a`) to be available for its exit code.

Importieren Sie `TestClient`.

Erstellen Sie einen `TestClient`, indem Sie ihm Ihre **FastAPI**-Anwendung übergeben.

Erstellen Sie Funktionen mit einem Namen, der mit `test_` beginnt (das sind `pytest`-Konventionen).

Verwenden Sie das `TestClient`-Objekt auf die gleiche Weise wie `httpx`.
