How to stub results?

[cedvw]

I can't figure out how to stub sunspot results in RSpec.

I added require 'sunspot/rails/spec_helper' to my spec/rails_helper.rb file, and call disconnect_sunspot at the top of my test.

My understanding is that running allow_any_instance_of(Sunspot::Rails::StubSessionProxy::Search).to receive(:results).and_return(['the results']) should be all I need to do for a search query to return ['the results'], but no matter what I try, I always end up with an empty array ([]) as results.

Here is a simplified version of my controller:

@search_results = MyModel.search do
                    fulltext params[:search]
                  end.results

And my test (simplified) looks like this:

require 'rails_helper'

RSpec.describe 'My controller' do
  disconnect_sunspot

  before do
    allow_any_instance_of(Sunspot::Rails::StubSessionProxy::Search).to receive(:results).and_return(['the results'])

    # Code that calls the controller here
  end

  it 'returns what I want' do
    expect(response.body).to eq(['the results'])
  end
end

And the RSpec results:

Failure/Error: expect(response.body).to eq(['the results'])
     
       expected: ["the results"]
            got: []
