# How To - Recipes { #how-to-recipes }

Here you will see different recipes or "how to" guides for **several topics**.

Most of these ideas would be more or less **independent**, and in most cases you should only need to study them if they apply directly to **your project**.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.

        assertEquals(metadataHashCode, SsoResponseType.METADATA.hashCode());
        assertEquals(logoutHashCode, SsoResponseType.LOGOUT.hashCode());

        // Different enum constants should have different hash codes (usually)
        assertNotSame(metadataHashCode, logoutHashCode);
    }

    @Test
    public void test_compareTo() {
        // Test compareTo method for enum constants

If you encounter a `RuntimeError: Task attached to a different loop` when integrating asynchronous function calls in your tests (e.g. when using [MongoDB's MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop)), remember to instantiate objects that need an event loop only within async functions, e.g. an `@app.on_event("startup")` callback.

## Injection de dépendances { #dependency-injection }

Utiliser `BackgroundTasks` fonctionne aussi avec le système d'injection de dépendances. Vous pouvez déclarer un paramètre de type `BackgroundTasks` à différents niveaux : dans une *fonction de chemin d'accès*, dans une dépendance (dependable), dans une sous-dépendance, etc.
