Testing whether a method in my controller was called

I want to test whether a method in my controller has been called or not.

My Controller looks like this:

def index
  if id_filters
    @products = Product.where(id: id_filters)
  else
    @products = Product.paginate(params[:page].to_i, params[:per].to_i)
  end

render json: @products, meta: @products.meta
end

I saw people using the code below to do this so I attempted to test it in RSpec with:

controller.stub!(:paginate).and_return true

however, I get an error:

undefined method `stub!' for #<ProductsController:0x00000102bd4d38>

I also tried:

controller.stub(:paginate).and_return true

same result though, it is an undefined method.

I think you mean to be stubbing Product, not the controller.

CORRECT SYNTAX

If you are using rspec before version 3.0 the correct syntax is

controller.should receive(:paginate).and_return(true)
# OR this equivalence
controller.should receive(:paginate) { true }
# OR (when you are in "controller" specs)
should receive(:paginate) { true }

If you are using rspec version 3.0 or higher the correct syntax is

expect(controller).to receive(:paginate) { true }
# OR (when you are in "controller" specs)
is_expected.to receive(:paginate) { true }

YOUR CODE

You seem to be testing paginate for Product so you syntax should be:

# Rspec < 3.0
Product.should receive(:paginate) { true }
# Rspec >= 3.0
expect(Product).to receive(:paginate) { true }
