Você aprenderá mais sobre como usar variáveis de ambiente para lidar com **configurações do aplicativo** no [Guia do Usuário Avançado - Configurações e Variáveis de Ambiente](./advanced/settings.md).

## Variável de Ambiente `PATH` { #path-environment-variable }

        // Replace with second customizer
        pagerCreator.setPagerCustomizer(customizer2);
        assertSame(customizer2, pagerCreator.getPagerCustomizer());
    }

    // Test setting null customizer
    @Test
    public void test_setPagerCustomizer_null() {
        // Create and set a customizer
        ComponentCustomizer customizer = new ComponentCustomizer() {
            @Override

    /**
     * Returns true if the call should retry on connection failures.
     */
    val retryOnConnectionFailure: Boolean

    /**
     * Returns a new chain with the specified retry on connection failure setting.
     */
    fun withRetryOnConnectionFailure(retryOnConnectionFailure: Boolean): Chain

    /**
     * Returns the [Authenticator] for the OkHttpClient, or an override from the Call.Chain.
     */

First, of course, you can mix `Path`, `Query` and request body parameter declarations freely and **FastAPI** will know what to do.

And you can also declare body parameters as optional, by setting the default to `None`:

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

* `skip=20`: because you set it in the URL
* `limit=10`: because that was the default value

## Optional parameters { #optional-parameters }

The same way, you can declare optional query parameters, by setting their default to `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

In this case, the function parameter `q` will be optional, and will be `None` by default.

/// check

        assertEquals("test", list.get(1));

    }

    @Test
    public void test_setMaxGroupDepth() {
        EntraIdAuthenticator authenticator = new EntraIdAuthenticator();

        // Test setting different max group depths
        authenticator.setMaxGroupDepth(5);
        authenticator.setMaxGroupDepth(20);
        authenticator.setMaxGroupDepth(1);

        // Verify method accepts valid values without exception

    // then FRQ does not bother to load Finalizer.class through a separate ClassLoader. That happens
    // in our test environment, which foils the purpose of this test, so we disable the logic for
    // our test by setting a static field. We are changing the field in the parallel version of FRQ
    // and each test creates its own one of those, so there is no test interference here.
