Unit tests mark territory more than squash bugs

This blog post critiques the effectiveness of unit tests in software development, drawing comparisons with hardware testing standards. The author argues that while unit tests have become pervasive, they are often ineffective at finding real bugs, with integration tests and randomizers being more effective alternatives. The primary role of unit tests has shifted to maintaining code stability amidst frequent changes in shared codebases, rather than targeting bug discovery. The piece highlights a practical solution involving random testing for better reliability, and discusses the cultural implications within software teams regarding testing practices.
