Using Silk Test Classic, you can create portable test cases that will test your application on any of the supported GUIs. The reason for this is that your test cases use logical names, called identifiers, to refer to the GUI objects, and not actual names, called tags. Therefore, if there are differences in the ported application’s appearance, you need only change the window declarations, not the test cases themselves.
The porting scenarios described section use 4Test keywords called GUI specifiers to indicate that portions of include files or script files are specific to a particular GUI. Before studying these scenarios, you should understand which GUI specifiers are available and how to use them in your include files and script files.
4Test includes a long list of GUI specifiers.
