How can I test that a field exists in a response using RSpec?

  • 772

I am testing for a API en RoR. I want to validate the structure of a response to a request from my API. I want to make sure that a particular field exists in that response and if it doesn't exist indicate that the test fails.

let(:user) { FactoryGirl.create(:user) }

describe "POST #create" do

    context "when logged in with identifier" do

        before(:each) do
            @user_attributes = { identifier: user[:email], password: '12345678' } 
            post :create, { session: @user_attributes }
        end

        it"when is valid token" do
            #como valido que en la respuesta exista el token
        end
    end
end

The responsepetition is as follows:

{"user": 
  {
   "id":9005,
   "email":"[email protected]",
   "first_name":"Serenity",
   "middle_name":"Keagan",
   "last_name":"O'Kon",
   "birthday":"2014-07 -01T04:30:00.000Z"
  },
 "token":"....."
 }

I am using RSpec 3.3.0andRails 4.2.3

    When you make a call to post, you get or should get an object as a response response. I recommend that you parse it to JSON to manipulate it better.

    it "when is valid id" do
  expect(JSON.parse(response.body).first.keys.include?("id")).to be(true)
end

    In general, the key is to parse as JSON and do something with the object response.body.
