When you run a test case, Silk Test Classic interacts with the application by executing all the actions you specified in the test case and testing whether all the features of the application performed as expected.
Silk Test Classic always saves the suite, script, or test plan before running it if you made any changes to it since the last time you saved it. By default, Silk Test Classic also saves all other open modified files whenever you run a script, suite, or test plan. To prevent this automatic saving of other open modified files, uncheck the Save Files Before Running check box in the General Options dialog box.
