Async before and after

[LMnet]

It is more feature request, than issue.
ATM all before and after stuff is fully synchronous: all methods returns Unit. It would be good to have a possibility to have an asynchronous versions of this methods. Typical use case for this async methods: operations with DB. For now i'm forced to use Await.ready to block my async operations.
I can suggest two options for the implementation:

1. Add extra methods into existent traits.
2. Add new traits, like BeforeAndAfterAllAsync.

Personally, I prefer the first way.

Hi @LMnet , in 3.0 we have made BeforeAndAfter and BeforeAndAfterAll to work with async style trait, I wonder if they fit your use case?

[LMnet]

I'm using 3.0 version with AsyncFreeSpec. But in BeforeAndAfterAll beforeAll and afterAll methods are synchronuous. I checked run method in BeforeAndAfterAll and I didn't find any async stuff there. If my action inside beforeAll or afterAll returns Future, I want to wait until it finished.

@LMnet That's done here:

https://github.com/scalatest/scalatest/blob/3.0.x/scalatest/src/main/scala/org/scalatest/BeforeAndAfterAll.scala#L223

The withAfterEffect method registers the afterAll code to run as an effect after the Status returned by super.run completes. The Status is kind of like a Future[Boolean].

@bvenners But what about before? withAfterEffect could replace only after method. And using this method looks like hack for me.

Is this issue solved already ?

I put up a related SOF question:

What exactly the solution for this ticket? I have requirements, where we need to call multiple future calls in the beforeAll method.

[bvenners]

We haven't done anything with beforeAll. Let me think about if that is possible, and if so how best to go about it.

What's the status of this issue?

I am also in need of an async beforeAll. Have not found any solution which does not include blocking (which is not possible in Scala.js).

Hi there! Is this issue already solved? I am also interested in it for Scala in JVM

How is this issue closed? Even if there's a workaround for an asynchronous afterAll, there's still no way to have asynchronous beforeAll.

Should I open a new issue?

Please reopen this issue as there is no possibility to execute asynchronous code in beforeAll()
