Question

上下文“答案是正确的”做

before(:each) do
  @answer = stub_model(Answer, :correct => true).as_new_record
  assigns[:answer] = @answer

  render "answers/summarize"
end

it "should display flashcard context properly" do
  response.should contain("Quiz")
end

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

端

上下文“答案不正确”执行

before(:each) do
  @answer = stub_model(Answer, :correct => false).as_new_record
  assigns[:answer] = @answer

  render "answers/summarize"
end

it "should display flashcard context properly" do
  response.should contain("Quiz")
end

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

端

如何在上述两种情况下避免重复以下块？

it "should display flashcard context properly" do

  response.should contain("Quiz")

端

Answer 1

您的规范描述了您希望从代码中获得的行为 - 这个重复次数是可以的。

如果失控，请使用不同的上下文来隔离不同的期望。例如，无论答案是什么，您都可以将这些重复期望纳入一个只测试页面的新上下文。

Answer 2

如果您真的想要完成一些测试，可以这样做：

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

正如您所看到的，当您想要在方法中包含多个测试时，这非常方便。
