# Testando { #testing }

Graças ao <a href="https://www.starlette.dev/testclient/" class="external-link" target="_blank">Starlette</a>, testar aplicações **FastAPI** é fácil e agradável.

Ele é baseado no <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, que por sua vez é projetado com base em Requests, por isso é muito familiar e intuitivo.

# Testando WebSockets { #testing-websockets }

Você pode usar o mesmo `TestClient` para testar WebSockets.

Para isso, você utiliza o `TestClient` dentro de uma instrução `with`, conectando com o WebSocket:

{* ../../docs_src/app_testing/tutorial002_py39.py hl[27:31] *}

/// note | Nota

# Testing Dependencies with Overrides { #testing-dependencies-with-overrides }

## Overriding dependencies during testing { #overriding-dependencies-during-testing }

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

# Testing WebSockets { #testing-websockets }

You can use the same `TestClient` to test WebSockets.

For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

{* ../../docs_src/app_testing/tutorial002_py39.py hl[27:31] *}

/// note

For more details, check Starlette's documentation for <a href="https://www.starlette.dev/testclient/#testing-websocket-sessions" class="external-link" target="_blank">testing WebSockets</a>.

# Тестирование WebSocket { #testing-websockets }

Вы можете использовать тот же `TestClient` для тестирования WebSocket.

Для этого используйте `TestClient` с менеджером контекста `with`, подключаясь к WebSocket:

{* ../../docs_src/app_testing/tutorial002_py39.py hl[27:31] *}
