Retry based on AssertionStep status

I managed to solve this specific problem, the opened support request shall remain open because I still suspect a problem with the .run() function.

Instead of trying to emulate the testRunner from inside the groovy step we now "drop an anchor" before the retry-cycle, run into the script and check the checkpoint status. If the status is FAIL we tell the testRunner to go back to the anchor via testRunner.gotoStep() - if the status is PASS we just let the TestCase continue on. Here is how that looks:

The anchor contains the number of remaining retry attempts, which are subtracted with each iteration by the ftpRetry-Script.

And here is the adapted ftpRetry function from the example.

void ftpRetry(def testRunner, def context){
  // variables to allow user to specify other names
  List<String> retryCheckpointNames = ['retryCheckpoint']
  List<String> retryAnchorNames = ['retryAnchor']
  int defaultRetryCount = 15
  ( checkpointStep, checkpointIndex ) = findStepInTestCase(context, true, retryCheckpointNames)
  ( anchorStep, anchorIndex ) = findStepInTestCase(context, true, retryAnchorNames)
  if(checkpointStep.getAssertionStatus().toString() != 'PASS') {
    // checkpoint did not pass, get the anchor, set the testRunner to the index of the anchor and subtract a retry from the anchor, then let everything run until this script is called again
    int retries = anchorStep.getPropertyValue('retries').toInteger()
    if(retries-- > 0) {
      anchorStep.setPropertyValue('retries', retries.toString())
      testRunner.gotoStep(anchorIndex + 1)
    }
    else {
      anchorStep.setPropertyValue('retries', defaultRetryCount.toString())
      assert false : "Out of retries, checkpoint-assertion failed every time!"
    }
  }
  else {
    log.info("Checkpoint passed, resetting retries on anchor.")
    anchorStep.setPropertyValue('retries', defaultRetryCount.toString())
  }
}

Should have reconsidered my approach to the problem rather than trying to force the script to emulate the testRunner, oh well.
