How to mock a current_user in rspec?

[gamesover]

If in keynote presenter, current_user is included.

def method(user)
  if user == current_user
  ...
end

In rspec, I don't know how to mock this current_user variable.

allow(presenter).to receive(:current_user).and_return(user) does not work and rspec said presenter is not defined.

Could you please show me an example?

Thanks.

If you look at the helper you'd see that you could provide the presenter instance yourself.

What sort of test are you writing? For what object, in what context, and what is the goal of the test?

@Spaceghost , if you look at my example method. There is a variable current_user from controller helper. How can I assign current_user a value when running rspec?

The context and environment of the test you're writing matters greatly here. Is this a "controller test"? Is it "integration"? "feature"? This must be answered in order to know how to provide the alternate to the context. Can you post the full test file and name if I've continued to poorly communicate? ~Spaceghost

Given a TestPresenter

class TestPresenter < Keynote::Presenter
  presents :test

  def get_current_user
    current_user 
  end
end

Please be noted, the current_user is defined in application_controller.rb, to use it in presenter is not issue. But how to test in rspec?

# frozen_string_literal: true

RSpec.describe TestPresenter do
  subject { k(test) }
  let(:test) { create(:test) }

  describe '#get_current_user' do
    it 'returns current_user' do
      expect(subject.get_current_user).to eq(user)
    end
  end
end

If you run the above rspec directly, it prompts error
NameError: undefined local variable or method current_user' for`

In this case, you need to stub the `#current_user` method or mock the receiver of `#current_user` ~Johnneylee
