Point1:
Make sure all tests are fully automatic and that they check their own result!
Point2:
A suite of tests is a powerful bug detector that decapites the time it takes to find bugs.
Point3:
Run your tests frequently. Localize tests whenever you compile---every test at least every day.
Point4:
When you get a bug report ,start by writing a unit test that exposes the bug.
Point5:
The key to testing is to test the areas that you are most worried about going wrong.，a key tricki with tests is to look for boundary conditions.
Point6:
It is better to write and run incomplete tests than not to run complete tests.
Point7:
Don't forget to test that exceptions are raised when things are expected to go wrong.
