Mutation testing is a method of evaluating and improving the quality of our test suites. It introduces subtle bugs to source code of our projects and checks that our tests catch those synthetic faults. High computational cost of this technique have prevented it from being widely used in our standard programming toolchain.
Can we try to sneak it in through the backdoor of our continuous delivery pipelines? How much of it can we automate? How can our version control system help us in the process?
Let’s try to answer those questions together.
