Interaction Based Testing: how does Spock know about asynchronous calls?

[Fedor Belov]

I've got following test:

setup:

MyService myMock = Mock()

anotherService.myService = myMock

when:

anotherService.doA(false)

then:

0 * myMock._

when:

anotherService.doA(true)

then:

1 *  myMock._

 doA asynchronously (with 2 seconds delay) calls myService. How does Spock checks asynchronous call (I checked it - if myService will be called in first case than test will fail)?

[Peter Niederwieser]

Spock can't possibly know that the calls happen asynchronously. It's the test's responsibility to not leave the `when` block until all asynchronous code triggered from within the block has finished.

[Witold Sowa]

Peter, do you know any better way than sleep(x) at the end of 'when' block to achieve it? Let's stick to Fedor's example as it is very clear.

You could use a `spock.util.concurrent.BlockingVariable` that is set in the mock response, and read in a condition in the then-block.

Cheers,

Peter

This is probably a little late.

I blogged about testing async here http://blog.stumblingoncode.com/posts/2014-11-06-ratpack-guava-eventbus.html

Another option would be to use polling conditions, see here http://docs.spockframework.org/en/latest/new_and_noteworthy.html
