stub is not defined while testing

Question

Suppose, I am running this test

Class MyModelTest < ActiveSupport::TestCase  
  def setup do
    @mymodel = MyModel.new
  end

  @mymodel.stub(:method).and_return { true }

but I get :undefined method 'stub' for nil:NilClass. I thought it was related to the nil instance, in fact when I dump with @mymodel with data, I get the same message undefined method stub'. Then I tried @mymodel.stubs(:method).and_return { true }, and I got this message

undefined method `and_return'

How can I solve that ?

Your original code is the `rspec` syntax, not `mocha` syntax — Uri Agassi, Apr 08 '14 at 11:23
@UriAgassi in fact if I implement the above response and I replace `stub` by `stubs`, it works. How is it so ? and what is in my code `rspec` type code since it can work with the indicated modifications ? — user1611830, Apr 08 '14 at 11:33
Maybe I confused you with the word "syntax". I meant API. `stub`, `and_return` are APIs of the `rspec` library. `stubs` and `return` are part of the `mocha` API. (@MarekLipka had a typo in his answer) — Uri Agassi, Apr 08 '14 at 11:39

Try this:

@mymodel.stubs(:method).returns(true)

yes it passes indeed but if and only if I replace `stub` by `stubs`. Why is it so ? – user1611830 Apr 08 '14 at 11:31
@user1611830 look at Uri Agassi's comment. – Marek Lipka Apr 08 '14 at 12:09
