如何使这些RSpec测试在Rails中更加干燥

如果需要跨控制器复制测试,可以使用rspec宏。创建 spec/macros/controller_macros.rb 用这样的方法:

def should_return_401_for_unauthenticated(test_controller)
  describe test_controller, "authentication requests" do
    it "should return 401 for show" do
      get :show
      response.code.should == "401"
    end
    it "should return 401 for create" do
      post :create
      response.code.should == "401"
    end
  end
end

describe MyController do
    should_return_401_for_unauthenticated(self)
end

describe "authentication requests" do

  limited_access = [:show, :create]

  limited_access.each do |action|
    it "should return 401 for unauthenticated :#{action}" do
      get action
      ## assert response 401
    end
  end

end

或者只做一次测试:

describe "authentication requests" do

  limited_access = [:show, :create]

  it "should return 401 for unauthenticated #{limited_access.to_sentence}" do
    limited_access.each do |action|
      get action
      ## assert response 401
    end
  end

end

可以添加一个spec\u helper方法来为您抽象它。。。可能性是无穷的。
