Unit Testing Like a Pro - Towards a Testable Design
summary
Practical guidance for writing maintainable, fast unit tests for Java projects: covers testing priorities, identifying and fixing brittle/buggy tests, using @Before, differences between mocks and stubs, reducing test doubles by "purifying" logic, testing and refactoring legacy code, and removing @Spy usages. Emphasizes how test design smells drive refactoring toward cleaner production code and advocates principles that improve testability rather than chasing coverage percent.
