      this currently only strips the `Assert` nodes from the graph and
      converts them into `NoOp`s instead.

/// tip | Dica

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 [MotorClient do MongoDB](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop)) 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")`.

/// info

The example above is actually an exception, because the `io.BytesIO` object is already in memory, so reading it won't block anything.

But in many cases reading a file or a file-like object would block.

///

/// tip | İpucu

Testlerinize asenkron fonksiyon çağrıları entegre ederken `RuntimeError: Task attached to a different loop` hatasıyla karşılaşırsanız (ör. [MongoDB'nin MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop) kullanımı), event loop gerektiren nesneleri yalnızca async fonksiyonların içinde oluşturmanız gerektiğini unutmayın; örneğin bir `@app.on_event("startup")` callback'i içinde.

/// info | Información

El ejemplo anterior es en realidad una excepción, porque el objeto `io.BytesIO` ya está en memoria, así que leerlo no bloqueará nada.

Pero en muchos casos leer un archivo u objeto tipo archivo sí bloquearía.

/// tip | Consejo

Si encuentras un `RuntimeError: Task attached to a different loop` al integrar llamadas a funciones asíncronas en tus tests (por ejemplo, cuando usas [MotorClient de MongoDB](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop)), recuerda crear instances de objetos que necesiten un loop de eventos solo dentro de funciones async, por ejemplo, en un callback `@app.on_event("startup")`.
