与RSpec的内置模拟框架相比，Mocha有何优势?

问题描述

我注意到，许多人比RSpec的内置模拟框架更喜欢Mocha.有人可以解释Mocha或其他替代方法相对于RSpec在模拟框架中内置的优势吗?

I notice that a lot of people prefer Mocha over RSpec's built in mocking framework. Can someone explain the advantages of Mocha, or any alternative, over RSpec's built in a mocking framework?

推荐答案

我真正喜欢的一个特定功能是能够存出类的所有实例.很多时候，我使用RSpec模拟执行以下操作:

One specific feature I really like is being able to stub out all instances of a class. A lot of times I do something like the following with RSpec mocks:

stub_car = mock(Car)
stub_car.stub!(:speed).and_return(100)
Car.stub!(:new).and_return(stub_car)

摩卡咖啡变成:

Car.any_instance.stubs(:speed).returns(100)

我发现Mocha版本更清晰，更明确.

I find the Mocha version clearer and more explicit.
