我如何才能有效地模拟一个流畅的界面与Spock Mocks？

Question

我想用mock模拟一些流畅的界面，它基本上是一个邮件构建器：

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

当用Spock嘲笑这一点时，这需要像这样的设置：

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

或者类似于Mockito的Deep Stubs（见http://docs.mockito.googlecode.com/hg/org/mockito/mockito.html#returns_deep_stubs)

Answer 1

您可以这样做：

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
}
