### Configurações e testes

Então seria muito fácil fornecer uma configuração diferente durante a execução dos testes sobrescrevendo a dependência de `get_settings`:

```Python hl_lines="9-10  13  21"
{!../../docs_src/settings/app02/test_main.py!}
```

    * **WebSockets**
    * uiterst gemakkelijke tests gebaseerd op HTTPX en `pytest`
    * **CORS**
    * **Cookie Sessions**
    * ...en meer.

Only differences from the base Go toolchain defaults are reported.

When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.
