Rspec方法返回的值应该是重定向

Question

I have:

def redirect_if_no_user
  if current_user.nil?
    redirect_to root_path
  end
end

in ApplicatonController . I would like to write a corresponding test:

Rspec.describe ApplicationController do

controller do
  def index
    render nothing: true
  end
end

describe '#redirect_if_no_user' do
  it 'redirects to root path' do
    get :index
    current_user = nil
    expect(response).to redirect_to(root_path)
  end
end

end

but I'm getting: Expected response to be a <redirect>, but was <200>

Any help?

Answer 1

When you write current_user = nil it will set a local variable. You need to nil out the controller's current_user which comes from its @current_user instance var. Or stub out the controller's current_user method to return nil.

Answer 2

Your anonymous controller does not call the filter, so add:

controller do
  before_filter :redirect_if_no_user # so it is called
  def index
    render nothing: true
  end
end

also test expect(current_user).to be_nil if defined? current_user expect(current_user).to be_nil if defined? current_user just to ensure correct input
