Rails - Rspec - stub params

I created some public method in controller which does some work.

def current_service
service_name = params[:controller].gsub('api/v1/', '').gsub(%r{/.+}, '')

I would like to test this method using RSpec but I dont't know how can I stub params. How should I do that?

If this is a controller spec, you should be able to do something like this:

allow(controller).to receive(:params).and_return({controller: 'a value'})

Alternatively, move the params[:controller] statement to a separate method and stub that in your spec.
