## Pin your `fastapi` version { #pin-your-fastapi-version }

The first thing you should do is to "pin" the version of **FastAPI** you are using to the specific latest version that you know works correctly for your application.

For example, let's say you are using version `0.112.0` in your app.

            return size;
        }
    }

    @DisplayName("Interface Contract Tests")
    class InterfaceContractTests {

        @Test
        @DisplayName("Interface should be correctly implemented by mock")
        void testInterfaceImplementation() {
            CreateContextRequest request = mock(CreateContextRequest.class);
            assertNotNull(request);

    @Test
    @DisplayName("Should create correct response")
    void testCreateResponse() {
        // When
        Smb2ChangeNotifyResponse response = request.createResponse(mockContext, request);

        // Then
        assertNotNull(response);
        assertTrue(response instanceof Smb2ChangeNotifyResponse);
    }

    @Test
    @DisplayName("Should calculate correct size")
    void testSize() {

Isso também te dá muita responsabilidade. Você precisa garantir que os dados retornados estão corretos, no formato correto, que podem ser serializados, etc.

## Utilizando o `jsonable_encoder` em uma `Response` { #using-the-jsonable-encoder-in-a-response }

///

Sempre que uma nova requisição for realizada, o **FastAPI** se encarrega de:

* Chamar sua dependência ("dependable") com os parâmetros corretos.
* Obter o resultado da função.
* Atribuir esse resultado para o parâmetro em sua *função de operação de rota*.
