Explore mutation testing for C++ in this 44-minute conference talk. Learn how to assess the effectiveness of your tests in catching bugs by intentionally inserting errors into your code. Discover different bug insertion techniques, understand the benefits of mutation testing, and examine the challenges in developing mutation testing tools. Dive deep into the design of new bug-inserting mutations specifically for C++. Gain insights into optimizations, vector mutations, lambda equivalence, error handling, and high-level mutations. Evaluate how much mutation testing is necessary for your projects and improve your overall testing strategy.
