我试图为rails api中的“show”操作编写一些测试
require 'rails_helper'
RSpec.describe AirlinesController, type: :controller do
describe "GET #show" do
before(:each) do
@airline = FactoryGirl.create(:airline)
get :show, id: @airline.id
end
it "should return the airline information" do
airline_response = json_response
expect(airline_response[:name]).to eql @airline.name
end
it {should respond_with :ok}
end
end
测试通过了。但是,当我尝试像这样使用
let
和subject
时require 'rails_helper'
RSpec.describe AirlinesController, type: :controller do
describe "GET #show" do
let(:airline) {FactoryGirl.create(:airline)}
subject {airline}
before(:each) do
get :show, id: airline.id
end
it "should return the airline information" do
airline_response = json_response
expect(airline_response[:name]).to eql airline.name
end
it {should respond_with :ok}
end
end
它显示了“nomethoderror undefined method`response'for…”
这让我很困惑!
最佳答案
不要设置subject
。控制器规范的主题是控制器,而不是模型对象。只要删除设置subject
的行,就不应该再出现该错误。
