UIAutomation and NSNotification

Question

I want to be able to use UIAutomation to test an app. The problem I'm running into is, I need to download allot of data from the network. Is there a way to pause a UIAutomation script until a NSNotification is posted, or do I just need to delay() longer than I think is necessary to download the data. Waiting a set amount of time isn't preferable because sometimes data doesn't need to be re-downlaoded.

Any help / links is greatly appreciated.

UIAutomation has a nifty function called waitForInvalid(). If you've got a progress bar or something that will get displayed and then removed after the data is done downloading, you could use that.

This also works for a case in which the user already has the data and you don't show the UI, since the function would immediately return.

Jack's answer works for most details, but some of the network work happens on a background queue, and there isn't a progress indicator.

I ended up writing a helper that sticks a CGRectZero UIView into an element. We can then wait until this element becomes valid. It's not as clean as I would like it to be but it's woking.

waitForElementNamed: function(name, element, timeout) {
  timeout = timeout || 10
  log("Waiting for " + timeout + " seconds")
  var valid = false
  for (var i = 0; i < timeout; i++) {
      UIATarget.localTarget().pushTimeout(.5)
      valid = element.elements()[name].isValid()
      if (valid) {
      log("Found Element " + name)
      return
      }
      UIATarget.localTarget().popTimeout()
      target.delay(.5)
  }
  if (!valid) {
      failed("Wait Timedout [" + timeout + "]")
  }
}

It's not pretty but it works.
