Observed behaviour

Getting equal error when using expect

Expected behaviour

Should be passing the test, according to the error description, or getting another error mesage

Code:

  RSpec.describe Api::V1::Profiles::ProfilesController, type: :api do
        describe 'POST /api/v1/profiles/profiles' do
              it 'Cadastro convencional de usuário (sem o facebook)' do
                    cpf = BRDocuments::CPF.generate(false)
                    post '/api/v1/profiles/profiles', :profile => {
                          :full_name => Faker::Name.name,
                          :email => Faker::Internet.email,
                          :password => "123456",
                          # :[lat] => '', 
                          # :[lng] => '', 
                          # :[fb_access_token] => '', 
                          :telephone => "2199919#{Random.rand(2520...4350)}", 
                          :cpf => cpf 
                          # :[photo] => '', 
                          # :[remote_photo_url] => ''
                    }
                    expect(last_response.status).to be(200)
                    expect(Profile.last.cpf.to_s).to be (cpf.to_s)
                  end
            end
      end

Result:

  1) Api::V1::Profiles::ProfilesController POST /api/v1/profiles/profiles Cadastro convencional de usuário (sem o facebook)
 Failure/Error: expect(Profile.last.cpf.to_s).to be (cpf.to_s)

   Compared using equal?, which compares object identity,
   but expected and actual are not the same object. Use
   `expect(actual).to eq(expected)` if you don't care about
   object identity in this example.

Hi, this is working as expected, if you read the error message:

Compared using equal?, which compares object identity,
but expected and actual are not the same object. Use
`expect(actual).to eq(expected)` if you don't care about
object identity in this example.

You will realise that you are using the be matcher and you need the eq matcher.

Additionally, Github issues are not the place to ask questions about your specs. In future please use the mailing list, stack overflow etc

@JonRowe Thanks that was it.

As you said, besides reading the log message a couple hundred times, I didn't realize the little eq. Sorry for that.

However, the error did not complain about/highlighted the be matcher, it was talking about equal?. I don't know if they're meant the be the same thing, but that was one of the reasons why I was not aware of the actual problem.

I apologize for posting this here, I thought maybe that was an error in the log message.

That is because be is an alias for equal, see http://rspec.info/documentation/3.8/rspec-expectations/#Identity
