Question

我正在尝试通过此规范，但我不知道这意味着什么。这是完整的规格。 第二个示例是失败的示例。

describe "PUT update" do
    describe "with valid params" do
      it "updates the requested experience_level" do
        experience_level = ExperienceLevel.create! valid_attributes
        # Assuming there are no other experience_levels in the database, this
        # specifies that the ExperienceLevel created on the previous line
        # receives the :update_attributes message with whatever params are
        # submitted in the request.
        ExperienceLevel.any_instance.should_receive(:update_attributes).with({ "name" => "MyString" })
        put :update, {:id => experience_level.to_param, :experience_level => { "name" => "MyString" }}
      end

      it "assigns the requested experience_level as @experience_level" do
        experience_level = ExperienceLevel.create!(name: 'test'), valid_attributes
        put :update, {:id => experience_level.to_param, :experience_level => valid_attributes}
        assigns(:experience_level).should eq(experience_level)
      end

      it "redirects to the experience_level" do
        experience_level = ExperienceLevel.create! valid_attributes
        put :update, {:id => experience_level.to_param, :experience_level => valid_attributes}
        response.should redirect_to(experience_level)
      end
    end

以下是终端中的消息：

1) ExperienceLevelsController PUT update with valid params assigns the requested experience_level as @experience_level
     Failure/Error: assigns(:experience_level).should eq(experience_level)

Answer 1

第二个例子中的以下陈述：

experience_level = ExperienceLevel.create!(name: 'test'), valid_attributes

与：

相同

experience_level = [ExperienceLevel.create!(name: 'test'), valid_attributes]

换句话说，它是从赋值运算符右侧的两个逗号分隔值创建一个数组，并将该数组赋给experience_level。这至少是您的测试失败的一个原因。

RSpec生成的测试“将所请求的experience_level分配为@experience_level”是什么意思？
