RSpec - 通用故障消息，而不是有用的輸出

Question

這是使用RSpec2 - 無論發生什麼事情，當期望不匹配時，我似乎得到以下錯誤。我敢肯定（雖然我不能嘗試一段時間）在版本1中，下面的代碼會聲明方法'方法'沒有被調用。

下面的代碼片段演示了這個問題 - 當在初始化中取消註釋該方法時，測試會通過。刪除註釋並返回通用錯誤消息。

describe "Test" do 
    it "should do" do 
    my_mock = mock("my mock") 
    my_mock.should_receive(:methods) 
    obj = Shaun.new(my_mock) 
    end 
end 

class Shaun 
    def initialize(mock) 
    #mock.methods 
    end 
end 

錯誤

Answer 1

正常工作在這裏，使用RSpec 2.0.1和1.8.7稀土元素。將需要再次檢查1.9.2，因爲我還沒有在這個系統上。評論

時：

    Failure/Error: my_mock.should_receive(:methods)
