ruby-on-rails - 如何干掉 Rails 的 RSpec 测试

Question

我正在学习 RSpec，但我注意到我的代码中有很多重复项。以下只是许多其他例子中的两个例子。有没有一种方法可以创建共享测试而不必遍历每个单独的属性？

  describe "validation" do
    describe "user_id" do
      it "should not be blank or nil" do
        @comment.user_id = nil
        @comment.should_not be_valid
        @comment.user_id = " "
        @comment.should_not be_valid
      end

      it "should an integer" do
        @comment.user_id = "a"
        @comment.should_not be_valid        
      end
    end

    describe "post_id" do
      it "should not be blank or nil" do
        @comment.post_id = nil
        @comment.should_not be_valid
        @comment.post_id = " "
        @comment.should_not be_valid
      end

      it "should an integer" do
        @comment.post_id = "a"
        @comment.should_not be_valid        
      end      
    end
  end
