如何使用Spock模拟有效地模拟流畅的界面？

Question

我想用mock模拟一些流畅的界面,这基本上是一个邮件生成器:

this.builder()
            .from(from)
            .to(to)
            .cc(cc)
            .bcc(bcc)
            .template(templateId, templateParameter)
            .send();

使用Spock进行模拟时,需要进行大量的设置:

def builder = Mock(Builder)
builder.from(_) >> builder
builder.to(_) >> builder 

当你想根据用例测试与模拟的某些交互时,它变得更加麻烦.所以我在这里基本上有两个问题:

1. 有没有办法结合模拟规则,以便我可以在一个方法中进行一般的一次性设置流程接口,我可以在每个测试用例上重复使用,然后为每个测试用例指定其他规则？

2. 有没有办法用较少的代码指定一个流畅的接口的模拟,例如:

   def builder = Mock(Builder)builder./(from|to|cc|bcc |template)/(*) >> builder

   或类似于Mockito的Deep Stubs的东西(参见http://docs.mockito.googlecode.com/hg/org/mockito/Mockito.html#RETURNS_DEEP_STUBS)

Answer 1

你可以这样做:

def "stubbing and mocking a builder"() {
    def builder = Mock(Builder)
    // could also put this into a setup method
    builder./from|to|cc|bcc|template|send/(*_) >> builder

    when:
    // exercise code that uses builder

    then:
    // interactions in then-block override any other interactions
    // note that you have to repeat the stubbing
    1 * builder.to("fred") >> builder
}
