Readability of individual test files is more important than maintainability in test code because tests are executed and read individually rather than being part of a larger system.

19. DRY (Don’t Repeat Yourself) matters much less in tests than it does in production code. Readability of an individual test file is more important than maintainability (breaking out reusable chunks). That’s because tests are executed and read individually rather than themselves being part of a larger system. Obviously excessive repetition means reusable components can be created for convenience, but it’s much less of a concern than it is for production.
