When I start to repeat myself in unit test methods by creating the same objects and preparing the data to run the test, I feel disapointed in my design.

TDD, Code review and Economics of Software Quality

software-development-2-logo

To understand the value of Junits (developer tests), try maintaining, or worst, refactoring a code base that has none. The cost of  maintaining such code is so high, that in most cases, it gets replaced instead of being improved or enhanced. The developer tests leads to ease of  maintenance and thus enable change. They are now a critical part of ...

Writing Clean Tests – Small Is Beautiful

software-development-2-logo
