## Використання `Annotated` у типі параметра `q`

Пам’ятаєте, як я раніше розповідав, що `Annotated` можна використовувати для додавання метаданих до параметрів у [Вступі до типів Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Зараз саме час використати його разом із FastAPI. 🚀

Раніше ми мали таку анотацію типу:

//// tab | Python 3.10+

```Python
q: str | None = None

        assertNotNull(securityDescriptor.getOwnerGroupSid());

    @DisplayName("Test decode with various ACE counts")
    @ValueSource(ints = { 0, 1, 10, 100, 1000, 4096 })

        // This test is theoretical as we can't create huge buffers

Você pode obter o `root_path` atual usado pela sua aplicação para cada solicitação, ele faz parte do dicionário `scope` (que faz parte da especificação ASGI).

Aqui estamos incluindo-o na mensagem apenas para fins de demonstração.

Então, se você iniciar o Uvicorn com:

<div class="termy">

```console

        // When
        int bytesRead = request.readBytesWireFormat(buffer, 0);

        // Then
        assertEquals(0, bytesRead);
    }

    @ParameterizedTest
    @ValueSource(ints = { 0, 10, 50, 100, 200, 500, 1000 })
    @DisplayName("Should handle various token sizes")
    void testVariousTokenSizes(int tokenSize) throws Exception {
        // Given
        byte[] token = createTestData(tokenSize);

        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @ParameterizedTest
    @DisplayName("Test writeBytesWireFormat with different input buffer sizes")
    @ValueSource(ints = { 0, 10, 50, 100, 255 })
    void testWriteBytesWireFormatWithDifferentBufferSizes(int bufferSize) {
        request = new Smb2QueryInfoRequest(mockConfig, testFileId);

        if (bufferSize > 0) {

            description,
            cls,
            explicitTestNames.get(0),
            cls.getName());
    return new AssertionError(message, e);

 *  Fix: Don't infinite loop when a received web socket message has self-terminating compressed
    data.

 *  Fix: Don't fail the call when the response code is ‘HTTP 102 Processing’ or ‘HTTP 103 Early
    Hints’.

 *  Fix: Honor interceptors' changes to connect and read timeouts.

 *  Fix: Recover gracefully when a cached response is corrupted on disk.

 *  Fix: Don't leak file handles when a cache disk write fails.
