- Does the events feedback-directed algorithm achieve significantly better coverage than initial?
Research Questions
- What level of code coverage is achieved by each of the test generation algorithms with the same number of tests?
Research Questions
- How quickly does each of the feedback-directed algorithms converge on the maximal coverage that it will achieve?
Research Questions
- How many HTML validity errors and runtime errors are detected by the different algorithms?
