why does this devise rspec model test fail ?

[Roelof Wobben]

Hello,

I did make a admin user with Devise with rails g devise Admin.

I see that I have name and password,

But when I test it with this :

describe "Admin" do 
  it { is_expected.to respond_to(:name) }
  it { is_expected.to respond_to(:password) }
  it { is_expected.not_to respond_to(:to_model) }
  it { is_expected.not_to respond_to(:compact, :flatten) }
end

I see this output :

expected "Admin" to respond to :name

 

This is saying 'expected the string "Admin" to respond', which isn't correct - you want to be testing against an instance of Admin.

 

You need to either describe the class so the correct automatic subject is created:

 

describe Admin do

  # ...

end

 

or explicitly assign a subject:

 

describe "Admin" do

  subject { Admin.new }

  # ...

end

 

fwiw, I wouldn't typically test that an object responds to specific methods, they don't tend to be valuable tests. Consider testing specific behaviours that you are interested in - those methods should all be executed.

 

Cheers,

Xavier

Thanks,

the problem was also that I forget to use reguruire 'test-helpers" .

This problem is solved.
