Running before / after when overriding withFixture

[Ferdinand Svehla]

What I’m trying to do is basically the opposite of Retries, since we want to eradicate flickers ASAP.

When mixed into a Suite, each test must pass N number of times before it is reported as passing.

I’m not overriding `runTest`, since I don’t want to report the running test multiple times, so I’m using

withFixture. However, “before” is only run once.

  override protected def withFixture(test: NoArgTest): Outcome = {
    val Times = 8


    @tailrec def rerunUntilPass(iteration: Int): Outcome = {
      if (iteration == Times) {
        // On the last invocation we just return the outcome
        super.withFixture(test)
      } else {
        super.withFixture(test) match {
          case Succeeded ⇒ rerunUntilPass(iteration + 1)
          case other     ⇒
            alert(s"Test `${ test.name }' failed at iteration ${ iteration } of ${ Times } needed")
            other
        }
      }
    }


    rerunUntilPass(1)
  }

How can I run before / after, or not emit reporter events when overriding `runTest`
