How to Prepare Flex Applications Under Test for Testing with UFT Flex add-in?


Depending on the scenario, end-users can test a Flex application using one of the following methods:


  • UFT Flex pre-compiled agent. Compile the application with the relevant Adobe or Apache Flex automation libraries and UFT Flex pre-compiled agent. This agent enables UFT to communicate with the application.


For more information, please refer to the document How to compile Flex application with to work with HP Flex add-in agent?




Below is a table for some scenarios (not all) and the available methods according to such:



Known Limitations


  • Backward compatibility with the Adobe Flex Add-in for QTP


UFT Flex Add-in does not provide backward compatibility with the Adobe Flex Add-in for QTP. For more information, please refer to the document https://softwaresupport.hp.com/group/softwaresupport/search-result/-/facetsearch/document/KM00514140


  • Cross-domain or cross-host Flex applications


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


  • Object Identification


UFT cannot recognize Flex test objects in windowless Flex applications. A windowless Flex application an wmode parameter defined as opaque or transparent, in the object element of a Flash Player object.


Workaround: Use the window value for the wmode parameter value, or remove the wmode parameter altogether. This workaround requires that users can modify the Web page that contains the Flex application object.


When identifying objects in a Flex application opened in a Web browser, the FlexWindow top-level test object is contained in a Page object.


UFT is not able to recognize a Flex application that is opened by specifying the URL of the SWF file in an Internet Explorer address bar.


Workaround: Create a simple HTML wrapper file to test the SWF file, using the following synatx:

Note: In this example HTML file, the SWF file being tested is named Main.swf.




<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="757" height="518" id="Main">

<param name="movie" value="Main.swf" />

<param name="quality" value="high" />

<param name="bgcolor" value="#ffffff" />

<param name="allowScriptAccess" value="sameDomain" />

<param name="allowFullScreen" value="true" />
