Paired Testing

Mutation testing promises to help ensure quality tests. It does this by making changes to a code base and running all tests. If all is well, some changes in code should result in failing tests. So making a bunch of changes like inverting the condition in an if-statement, should cause the tests to fail. If not, the test isn’t good enough.
I’ve tried this technique a couple of years ago, and wanted to find out what had changed.
