Related issue(s)

• VI-471

Testing done

• New code is covered by unit tests
• This is difficult to test without being on staging but the validations and object creation with a dummy response can be tested.
  • in the mhv_account_creation_response method add a dummy response

   def mhv_account_creation_response
     {
       user_profile_id: '12345678',
       premium: true,
       champ_va: true,
       patient: true,
       sm_account_created: true,
       message: 'some message'
     }
   end

• in rails console test the Sidekiq job by passing a user_verification.id you have locally
  • a user_verification.user_account.terms_of_use_agreements needs to exist & be accepted

    > mhv_account = MHV::AccountCreatorJob.new.perform(5)
       => #<MHVUserAccount:0x00007213e4c3f950 @attributes=...>
    > mhv_account.attributes
       => {"user_profile_id"=>"12345678", "premium"=>true, "champ_va"=>true, "patient"=>true, "sm_account_created"=>true, "message"=>"some message"
    

  • test the error response with a bad user_verification id

    > mhv_account = MHV::AccountCreatorJob.new.perform(55555)
    Rails -- MHV AccountCreatorJob failed: UserVerification not found for id 55555
