ion, so mapping between GUI events and the underlying code is not straightforward. Code-based coverage criteria do not necessarily address problematic interactions between the GUI's user events and the application. Second, even when experienced test designers focus on specific parts of a GUI, they may still find it impractical to generate all possible test cases for these parts. If the designers have to generate a subset of all possible test cases, they often must select the subset during test case generation. The difficulty of anticipating a test case's fault-detection capability makes it difficult, in turn, to select the most effective subset. Test oracles Verifying whether the GUI executes correctly poses a problem. The traditional verification tool is a test oracle-a separate program that generates expected results for a test case and compares them with actual results. In conventional software testing, the tester invokes the oracle after the test case executes and compare...
