General Limitations

  • The Flex Add-in does not provide backward compatibility with the Adobe Flex Add-in for QuickTest, and uses a different set of test objects, methods, and properties. Legacy QuickTest tests recorded using the Adobe Flex Add-in cannot be used, and they cannot be upgraded to be used with the UFT One Flex Add-in.

  • The Flex Add-in does not support cross-domain or cross-host Flex applications.

  • The Flex Add-in is not supported on Internet Explorer 11 when the Enhanced Protected Mode is turned on.

  • Testing Flex applications in UFT One is supported only on Internet Explorer 32-bit browser versions.

  • The UFT One Flex Runtime Loader does not support applications that contain mx::AreaChart controls.

  • To communicate with the Flex application, UFT One selects an available port within the range 24654 - 24663. Make sure that at least one of these ports is available on the UFT One computer.

    • On a Windows server, multiple users can run multiple instances of UFT One. To test Flex applications, you must have one port in this range available for each UFT One instance.

    • If you are testing a Flex application, you may experience a delay (up to one minute) from the moment you open UFT One and your Flex application, until UFT One can recognize objects in the application. This is due to the time it may take for UFT One to locate an available port, as it cycles through the ports in this range, waiting for the socket connection timeout for each.

  • If you are using Flex SDK version 3.6.0, you must set the Flash Player target version to 10.2 or higher when compiling your Flex application.

  • If you are using Flex SDK version 3.6.0, the precompiled agent is the only supported method of preparing your application for testing. the Runtime loader and Flash Player Debugger methods are not supported.
