Quality Code: Software Testing Principles, Practices, and Patterns

Unit Testing under Code Checker Constraints

Earlier, I mentioned that you should use tools to automate as many craftsmanship concerns as you can. If your tests drive the quality of your development, then you need to apply good craftsmanship to your tests as well. Not only should your tools check your application code, they should also check your test code to almost the same standards. I say “almost” because some reuse heuristics for production code need to be relaxed in test code. For example, repetition of string values between tests helps to keep your tests independent of each other, although using different strings is even better. Similarly, while refactoring for reuse benefits test code, you should not refactor tests in a way that blurs ...
