Se você se deparar com um `RuntimeError: Task attached to a different loop` ao integrar funções assíncronas em seus testes (e.g. ao utilizar o <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MotorClient do MongoDB</a>) Lembre-se de instanciar objetos que precisam de um loop de eventos (*event loop*) apenas em funções assíncronas, e.g. um callback `@app.on_event("startup")`.

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