easy-to-use graphics interface

With Pro-Test, you don't need to rely on scripting languages or code files. The easy-to-use graphical user interface lets you generate test cases using a familiar spreadsheet interface.

constraints

Using the constraint editor, easily identify factors and levels which are not feasible. Pro-Test will generate all pairs which do not violate the constraints.

previous test/Desired Test

Using the Previous Test tab, enter the test cases that have either been already completed or test that you would like to run. Pro-Test will augment these tests with cases that cover all the possible pairs.
