The Mutation Testing Framework (MTF)

The Mutation Testing Framework (MTF) is a tool used to evaluate the effectiveness of software tests. It works by making small changes—or "mutations"—to the code and then running the tests. If the tests catch these changes and fail, it shows they are good at detecting errors. If not, it indicates the tests might need improvement. MTF helps developers identify weak points in their testing process, ensuring the software is more reliable by encouraging stronger, more comprehensive test cases.
