/// tip

Notice that the testing functions are normal `def`, not `async def`.

And the calls to the client are also normal calls, not using `await`.

This allows you to use `pytest` directly without complications.

Note that the parameters inside the function have their natural data type, and you can, for example, perform normal date manipulations, like:

        doc.documentElement.depthFirst().findAll { it.name() == 'programlisting' || it.name() == 'screen' }.each {Element element ->
            element.setTextContent(normalise(element.getTextContent()))
        }
    }

    static String normalise(String content) {
        content.replace('\t', '    ').stripIndent().replace('\r\n', '\n')
    }

# GraphQL { #graphql }

Como **FastAPI** se basa en el estándar **ASGI**, es muy fácil integrar cualquier paquete de **GraphQL** que también sea compatible con ASGI.

Puedes combinar las *path operations* normales de FastAPI con GraphQL en la misma aplicación.

/// tip | Consejo

**GraphQL** resuelve algunos casos de uso muy específicos.

Tiene **ventajas** y **desventajas** en comparación con las **APIs web** comunes.

        // Test default max reading num
        assertEquals(10, converter.getMaxReadingNum());
    }

    @Test
    public void testInitNormal() throws IOException {
        // Test normal initialization
        converter.init();
        assertTrue(testConverter.isInitialized());
    }

    @Test
    public void testInitMultipleTimes() throws IOException {
        // Test multiple initialization calls

## HTTPX { #httpx }

Mesmo que a sua aplicação **FastAPI** utilize funções normais com `def` no lugar de `async def`, ela ainda é uma aplicação `async` por baixo dos panos.

Although any other parameter declared normally (for example, the body with a Pydantic model) would still be validated, converted, annotated, etc.

But there are specific cases where it's useful to get the `Request` object.

            return null;
        }

        String s = stripBasedirToken(path);

        File file = new File(s);
        if (file.isAbsolute()) {
            // path was already absolute, just normalize file separator and we're done
            s = file.getPath();
        } else if (file.getPath().startsWith(File.separator)) {
            // drive-relative Windows path, don't align with project directory but with drive root
