BDD测试框架Cucumber

BDD： Behaviour-Driven Development (BDD) 行为驱动开发

一般软件的开发涉及到三个角色
PO(Product owner) : 产品经理 
Tester: 测试
Developer: 研发

三者之间的关系:
PO来根据customer需求来写feature, 
software teams根据feature的描述来实现需求
Tester根据featuer来测试develper的实现。

cucumber是实现BDD 模式开发的一个框架, 现在很多大的公司使用这种开发模式,来快速迭代开发新的feature

可以用来测试service的API，Service与service之间的调用, 保障系统的可靠性

PO来负责提供feature,
Developer来实现feature 需求
tester可以根据feature来写实现的测试

增加了开发的速度

PO来负责提供feature,
Developer来实现feature 需求

Runcakes是cucumber来检验feature的一个Driver class.
Runcakes会根据根据feature里的scenarios来匹配对应的step definations并运行scenario来检验feature实现
