A scalable system and method is described that automatically identifies one or more generic tests for testing a GUI. A generic test case is written once instead of writing test cases for every single page or assembly. Each page has a corresponding page type. Each generic test is mapped to one or more testing rules, where the testing rules each have a rule type. An automated system is provided to scan target directories for all relevant pages related to a software product, identify a page type for each page, identify the appropriate generic test cases to be applied to each page, execute the generic test cases, and provide an output to indicate the results of the tests on the various pages. The generic tests for the GUIs can thus be automatically applied to identify and eliminate a certain class of bugs matching the behavior of the generic test case.
