How to check whether my object has a key?

Question

I am executing three different cases for my login method, on successful login i receive the below auth token

{"auth":"eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6IkRpZGllci5EZXNjaGFtcHNAbm93aGVyZS5jb20iLCJoYXNoIjoiMFIzM3lnckhJNTNjNDg1NDA4YzliZWUzZDEyM2UwZTQwY2I3OTc3YWEiLCJuYW1lIjoiRGlkaWVyIiwidXNlcmlkIjoyLCJhY2NvdW50aWQiOjB9.884v-blMRHE-VgYOvuJIOwZHNhuaKuhprYO9xU6IYtE"}

How do i check whether my user object has the auth key or not in rspec to pass the test.

require 'spec_helper'

describe User do

  context "when signing in" do

    it "should not login with invalid code" do       
      user = User.login(email: email, password: password, confirmpassword: password, code: 10000);
    end

    it "should not login with no code" do 
      user = User.login(email: email, password: password, confirmpassword: password, code: "");
    end

    it "should login with valid code" do 
      user = User.login(email: email, password: password, confirmpassword: password, code: 0);
    end

  end

end

This should work:

expect(user.auth).not_to be_nil

vs

expect(user.auth).to be_nil

I can execute three it statements inside a context right? – UnderTaker Aug 11 '14 at 09:44
You can execute as many `it`s within context as you need, this is what context is for. – BroiSatse Aug 11 '14 at 09:50
I am just worried, if the response does not have a auth key itself... in that case user.auth.to be_nil might fail – UnderTaker Aug 11 '14 at 09:56
Why wouldn't it have this key? I have too little information about your models to tell you more, but if you are using external APIs, you should always stub them in your tests. – BroiSatse Aug 11 '14 at 09:57
Then naturally your test has to fail. Isn't that what you are testing here? – BroiSatse Aug 11 '14 at 10:00
Yup that would fail, would that be more helpful? – UnderTaker Aug 11 '14 at 10:03

Can you just check this thread and let me know whether its right what i am doing. http://stackoverflow.com/questions/25273062/rspec-checking-for-json-response – UnderTaker Aug 12 '14 at 20:05

I think that something like

expect(user).to have_key(:auth)

and

expect(user).to_not have_key(:auth)

can do the job.

check the docs for more matchers.

`have_key` is reserved for hashes. Unfortunately, even though ActiveRecord defines `[]` method, ti is not a hash and does not respond to `has_key` method, hence the above won't work. – BroiSatse Aug 11 '14 at 09:53
