Yes, and it happens more than you think!](https://www.gregorykapfhammer.com/blog/test-flimsiness-mutation-flakiness/) _2026-01-01 · Gregory M. Kapfhammer · Blog_ Introduction What if changing the code under test — not the test itself and not the execution environment — could turn a perfectly stable test case into a flaky one? That is exactly what my colleagues and I discovered in a new phenomenon that we call “test flimsiness”. The name is an acronym since FLIM siness stands for FL akiness I nduced by M utations to the code under test. In (Parry et al.… ## [Insights from my Software Engineering Radio interview with Jennings Anderson and Amy Rose](https://www.gregorykapfhammer.com/blog/se-radio-jennings-anderson-amy-rose-overture-maps/) _2025-12-15 · Gregory M.

Kapfhammer · Blog_ Introduction Are your tests as effective as you think they are? While statement coverage is a common metric for test suite quality, it often doesn’t tell the whole story. High coverage scores can create a false sense of security, leaving critical “gaps” in your testing strategy. In the paper (Maton, Kapfhammer, and McMinn 2025) , my colleagues and I investigate how to identify an “oracle gap” that… ## [When flaky tests fail together: Empirical evidence for systemic flakiness](https://www.gregorykapfhammer.com/blog/discover-systemic-test-flakiness/) _2025-05-30 · Gregory M. Kapfhammer · Blog_ Introduction Have you ever noticed that when one flaky test fails in your continuous integration pipeline, several others seem to fail at the same time? Well, you’re not imagining things! My colleagues and I recently completed a comprehensive study that reveals flaky tests often exist in clusters, failing together due to shared root causes. We call this phenomenon systemic flakiness , and we think… ## [Insights from my Software Engineering Radio interview with Will McGugan](https://www.gregorykapfhammer.com/blog/se-radio-will-mcgugan-text-interfaces/) _2025-05-21 · Gregory M.

Kapfhammer · Blog_ Introduction When software developers talk about problematic test suites, the conversation often begins and ends with flaky tests. And while flakiness is certainly a serious concern, is it really the only symptom of an unhealthy test suite? My colleagues and I argue that it is not. In (McMinn, Roslan, and Kapfhammer 2025) , published at the 2nd International Flaky Tests Workshop, we present a… ## [Try Before You Buy, Risk-Free (Sponsored)](https://crawlproof.com/a/rYcHUBYjQCcN) _2024-12-31 · **Sponsored**_ Free trial hosting plus refunds processed in 12-24 hours, guaranteed. ## [Using eXtreme mutation testing to discover hidden test suite weaknesses](https://www.gregorykapfhammer.com/blog/pseudosweep-extreme-mutation-testing/) _2024-10-01 · Gregory M. Kapfhammer · Blog_ 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… ## [Insights from my Software Engineering Radio interview with Itamar Friedman](https://www.gregorykapfhammer.com/blog/se-radio-itamar-friedman-automated-testing/) _2024-09-11 · Gregory M.
