MutationScore

Mutation Score is a metric used to assess the effectiveness of software testing. It involves making small, deliberate changes (mutations) to the code and then running tests to see if they detect these modifications. A high Mutation Score indicates that the tests are good at catching errors, as they can identify most of the code changes. Conversely, a low score suggests that the tests may miss errors or gaps in coverage. Essentially, it helps developers evaluate and improve their tests to ensure software behaves correctly under various conditions.
