Waiting on a Future
The Await.result method is waiting for the result to be available. We have the possibility to give a timeout to the method so that it does not block forever.
The signature is as follows:
Await.result(awaitable: Awaitable[T], atMost: Duration)
The first parameter waits for Awaitable (Future extends Awaitable), and the second is Duration. Duration is the time to wait before throwing TimeoutException.
This is a pretty convenient method to get the value in our test.
If you add import scala.concurrent.duration._ in the import section, you can use a Domain Specific Language (DSL) to express the duration in plain English, as follows:
1 second
2 minutes
