How Code Coverage Drives Quality: A Proven Approach
How Code Coverage Drives Quality: A Proven Approach The way we create quality software has evolved dramatically over the years. One of the most significant shifts I’ve observed is the responsibility for quality moving squarely onto the shoulders of those writing the code: the engineers. It’s no longer acceptable to rely on QA teams or others downstream to ensure that what we release to customers meets the highest standards. Quality is everyone’s job, and it starts with the code we write. One powerful tool to promote this accountability and improve overall quality is code coverage metrics . By requiring engineers to measure and meet coverage goals, we nudge them toward building automated tests that not only prevent bugs today but also safeguard the codebase as it evolves. The Impact of Requiring 80% Code Coverage Years ago, my teams implemented a requirement: every new code check-in must have at least 80% code coverage . It took a little bit of time but the results were incredible...
