The Way of Testivus

• If you write code, write tests.
• Don’t get stuck on unit testing dogma.
• Embrace unit testing karma.
• Think of code and test as one.
• The test is more important than the unit.
• The best time to test is when the code is fresh.
• Tests not run waste away.
• An imperfect test today is better than a perfect test someday.
• An ugly test is better than no test.
• Sometimes, the test justifies the means.
• Only fools use no tools.
• Good tests fail.
