Contract Test

本文主要是介绍Contract Test，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Diaspar wrote in Contract Test:
Contract Tests explain how a class should extend a superclass or implement and interface, so that I don't have to read a bunch of prose to figure out how to do that.

一直困扰我的关于如何告诉其他人正确使用我写的基类的问题，通过contract test即可以较好的解决:

Typically, a contract test case class is abstract, then I extend it and implement a creation method or two to return instances of my own implementation of the given interface. That gives me a standard battery of tests I can run to drive my implementation. It might not be perfect (I'll have n failing tests to start) but I prefer it to documentation written in prose.

So if you're delivering something you want me to extend and I need to follow more than three rules, please deliver me some contract tests.

又google了一下，找到Joe Walnes一篇相关的Blog:Design by contract: testing implementations of interfaces

这篇关于Contract Test的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
