Use Saboteurs to Test Your Testing
让搞破坏的人测试你的测试用例。
When writing tests, make sure that alarms sound when
they should.
好的测试用例应该是出现问题是能够及时捕获。
Test State Coverage, Not Code Coverage
测试状态覆盖,而不是代码覆盖。
If a bug slips through the net of existing tests, you
need to add a new test to trap it next time. The Author calls this “tighten the
net”.
任何漏网之鱼,都说明你的网有漏洞,你需要修补好你的网。确保不会有同样的鱼从哪里逃走。Bug也是一样的道理。
