Book Description

  设想把编程看成是转动曲柄从井里提一桶水上来的过程。如果水桶比较小,那么仅需一个能自由转动的曲柄就可以了。如果水桶比较大而且装满水,那么还没等水桶全部被提上来你就会很累了。你需要一个防倒转的装置,以保证每转一次可以休息一会儿。水桶越重,防倒转的棘齿相距越近。 测试驱动开发中的测试程序就是防倒转装置上的棘齿。一旦我们的某个测试程序能工作了,你就知道,它从现在开始并且以后永远都可以工作了。相比于测试程序没有通过,你距离让所有的测试程序都工作又近了一步。现在我们的工作是让下一个测试程序工作,然后再下一个,就这样一直进行。分析表明,要编程解决的问题越难,每次测试所覆盖的范围就应该越小。
