I have tried couple of tools that promise automating UI testing for Flash application. The issue I run in is majority of them work on ActionScript3 or higher versions and my application is built on ActionScript1. I have tried Image based recognition tools like eggPlant, then I tried Ranorex, also Selenium, but none could yield more than a coordinate based record/replay script for me since my AS1 Flash controls could not be identified.
TestComplete claims to support testing of Flash application and it says of providing access to individual UI level components like text box, grid, combo boxes, checkboxes etc. Anyone has any experience using TestComplete to test any AS1 based Flash application that they can share.
