### Die Responses testen { #check-the-responses }

Wenn Sie nun zur URL mit dem Port für Uvicorn gehen: <a href="http://127.0.0.1:8000/app" class="external-link" target="_blank">http://127.0.0.1:8000/app</a>, sehen Sie die normale Response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

    client = TestClient(app)
    response = client.get("/test1")
    assert response.status_code == 200
    assert response.json() == {"foo": "bar"}

    response = client.get("/test1", params={"var": "baz"})
    assert response.status_code == 200
    assert response.json() == {"foo": "baz"}

    response = client.get("/test2")
    assert response.status_code == 200
    assert response.json() == {"foo": "bar"}

Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:

{* ../../docs_src/handling_errors/tutorial004_py39.py hl[3:4,9:11,25] *}

/// note | Detalhes Técnicos

Você pode usar `from starlette.responses import PlainTextResponse`.

    app.post("/endpoint2")(passthrough(passthrough(forwardref_method)))
    with client:
        response = client.post("/endpoint", json={"input": {"x": 0}})
        response2 = client.post("/endpoint2", json={"input": {"x": 0}})
