In 1990, Boris Beizer, in his book Software Testing Techniques, Second Edition, coined the term pesticide paradox to describe the phenomenon that the more you test software, the more immune it becomes to your tests. The same thing happens to insects with pesticides. If you keep applying the same pesticide, the insects eventually build up resistance and the pesticide no longer works.

术语”杀虫剂悖论“（The Pesticide Paradox）用来描述这样一种现象，即你对软件进行越多的测试，那么该软件对你的测试就越具有免疫力。同样的事情发生在对昆虫使用杀虫剂上。如果你持续使用同样的杀虫剂，这些昆虫最终将建立起抵抗力，杀虫剂将不再发挥作用。

To overcome the pesticide paradox, software testers must continually write new and different tests to exercise different parts of the program and find more bugs.

为了克服”杀虫剂悖论“，软件测试人员必须不断地编写新的不同的测试来检验程序的不同部分从而找出更多的bug。

Having another set of eyes look at the software helps break the pesticide paradox.

让其他的人来测试你的程序将有助于打破”杀虫剂悖论“。
