我如何避免在上述两个上下文中重复以下块？

it "should display flashcard context properly" do 

    response.should contain("Quiz")

Answer 1

您的规格说明你从你的代码所期望的行为 - 重复这一数额是确定的。

如果失控，请使用不同的上下文来隔离不同的期望。例如，您可以将这些重复的期望因素放入一个新的上下文中，无论Answer是什么，它都只是测试页面。

Answer 2

如果你真的想换一些你的测试，你可以做这样的：

def answer_tests 
    it "should display flashcard context properly" do 
    response.should contain "Quiz" 
    end 

    it "should do be awesome" do 
    response.should be_awesome 
    end 
end 

context "answer is correct" do 
    answer_tests 

    it "should summarize results" do 
    response.should contain "is correct" 
    end 
end 

context "answer is incorrect" do 
    answer_tests 

    it "should summarize results" do 
    response.should contain "is incorrect" 
    end 
end 

正如你所看到的，这是非常方便的，当你有一个以上的测试，你想包装在一个方法中。
