Rspec在any_instance上模拟完全(n)次

Question

我想在rspec测试中使用Mocks.

klass.any_instance.should_receive(:save).exactly(2).times.and_return(true)

但我收到一条错误消息:

'消息"save"由<#Object>接收,但<#Object>已收到

临时我使用存根但准确性要使用模拟

该文件的any_instance.should_receive方法是:

Use any_instance.should_receive to set an expectation that one (and only one)
instance of a class receives a message before the example is completed.

所以你已经指定了一个对象应该接收save两次调用,而不是那两个对象应该接收save一次调用.

如果您想计算不同实例所做的调用,您必须具有以下创造性:

save_count = 0
klass.any_instance.stub(:save) { save_count+=1 }
# run test
save_count.should == 2
