Using eXtreme mutation testing to discover hidden test suite weaknesses

Introduction Ever wondered if your test suite is truly good at finding bugs? What if there are hidden weaknesses that traditional testing methods miss? In the paper (Maton, Kapfhammer, and McMinn 2024a) , my colleagues and I explore how eXtreme mutation testing (XMT) can uncover these hidden weaknesses in your test suite. By identifying pseudo-tested methods — or those methods in your program that…
