RSpec-测试方法是否调用了其块参数 [英] RSpec -- test if method called its block parameter

问题描述

我有一个采用代码块作为参数的方法.问题是:如果此方法调用了块，如何使用RSpec进行测试?

I have a method that takes block of code as an argument. The problem is: how to test using RSpec if this method called the block?

可以在方法需要的任何范围内评估块，而不必使用yield或block.call.它被传递给另一个类，或在匿名类对象或其他地方对其进行求值.要使测试通过，就可以通过方法调用在某处评估块.

The block may be evaluated in any scope the method needs, not necessarily using a yield or block.call. It be passed to another class, or evaluated it in an anonymous class object or somewhere else. For the test to pass it is enough to evaluate the block somewhere as a result of the method call.

是否可以使用RSpec测试类似的东西?

Is there a way to test something like this using RSpec?

推荐答案

我通常会做类似的事情

a = 1
b.go { a = 2}
a.should == 2
