Hi Folks, I've been beating my head against a problem and I'm hoping someone out there can help. I'm writing some test cases for our Flex application using Flex Unit 4 (RC 2) and we are currently building with the Flex 3.2 SDK in Flash Builder 4.
The problem I'm seeing is when I add UI elements to the UIImpersonator they never finish setting up (i.e. their creation complete event is never triggered, never initialized, etc.). Per the directions at http://docs.flexunit.org/index.php?title=UIImpersonator I've set up my test case instantiating the component in the [Before], added the Async listener on the creation complete, etc. In fact, just to make sure I didn't have a typo I took their complete example and pasted it in as a test case. No dice. Source code I'm using below the description here. In every instance I get a 'Timeout occurred before expected event' error. Just to troubleshoot I tried adding the UI element as a child to the Application instead of the UIImpersonator (sorry to make your spine shiver, Douglas. It's just for troubleshooting, honest!). That worked fine so I know the Async proceedOnEvent is working fine. I also tried just removing the Async.proceedOnEvent but in that case the text input box is never initialized. Searching online some folks said that the problem may be with the VisualTestEnvironmentBuilder (which apparently UIImpersonator uses) but I haven't found anyone discussing how to _fix_ it. Any suggestions or help are appreciated.
