When you change your code, you may need to re-run tests to ensure they achieve the same coverage. Re-running tests is expensive, both in terms of testing time on target, and engineering effort.
The Optimal Dataset Calculator calculates the optimal set of tests required to achieve maximum coverage, helping you reduce testing effort and overhead. The standalone wizard guides you through configuring the cost of each test (either by test duration, or another relevant metric such as engineer hours), and defining the functions, files and folders for which you want to achieve coverage. You can use the results of the Optimal Dataset Calculator to focus your testing effort, and avoid running unnecessary or redundant tests.
