- http://blog.eisele.net 4 Testing is too hard. Testing isn’t fun. Testing is so sloow. Testing sucks!

- http://blog.eisele.net 5 Unit Tests Integration Tests System Tests Complexity Functional Test Code

- http://blog.eisele.net 6 You can’t fix what you can’t run.

- http://blog.eisele.net 7 You can’t fix what you can’t debug.

- http://blog.eisele.net 8 You can’t fix what you can’t test.

- http://blog.eisele.net 9 You can’t develop what you can’t test.

- http://blog.eisele.net 10 Not testing needs to be more painful And time consuming than using testing.
