测试 WebSockets 也使用 `TestClient`。

为此，要在 `with` 语句中使用 `TestClient` 连接 WebSocket。

이를 위해 `with` 문에서 `TestClient`를 사용하여 WebSocket에 연결합니다:

# Тестирование событий: lifespan и startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Если вам нужно, чтобы `lifespan` выполнялся в ваших тестах, вы можете использовать `TestClient` вместе с оператором `with`:

<!--
    We used to set this only for packages that had manual supersource. That
    worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same

# 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).

# Testen mit Überschreibungen für Abhängigkeiten { #testing-dependencies-with-overrides }

## Abhängigkeiten beim Testen überschreiben { #overriding-dependencies-during-testing }

Es gibt einige Szenarien, in denen Sie beim Testen möglicherweise eine Abhängigkeit überschreiben möchten.

Sie möchten nicht, dass die ursprüngliche Abhängigkeit ausgeführt wird (und auch keine der möglicherweise vorhandenen Unterabhängigkeiten).

# Testando Dependências com Sobreposições { #testing-dependencies-with-overrides }

## Sobrepondo dependências durante os testes { #overriding-dependencies-during-testing }

Existem alguns cenários onde você deseje sobrepor uma dependência durante os testes.

Você não quer que a dependência original execute (e nenhuma das subdependências que você possa ter).

# Тестирование базы данных { #testing-a-database }

# Тестирование WebSocket { #testing-websockets }

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

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

# Probando Dependencias con Overrides { #testing-dependencies-with-overrides }

## Sobrescribir dependencias durante las pruebas { #overriding-dependencies-during-testing }

Hay algunos escenarios donde podrías querer sobrescribir una dependencia durante las pruebas.

No quieres que la dependencia original se ejecute (ni ninguna de las sub-dependencias que pueda tener).
