So I am setting up rspec on a non tested codebase. I am starting with endpoint testing. I am relying a lot on shared example to DRY. My setup worked well like follow : (simplified for readability)

describe Api::V2::EventsController, type: :api do
 let(:type) 'events' 
 let(:instance_trait) :with_events 
 let(:record_count_transiant) :events_count 

 subject controller 
 it_behaves_like 'index'
end


RSpec.shared_examples 'index' do
 context 'index without data' do
 it_behaves_like 'empty_index'
 end
end

RSpec.shared_examples 'empty_index' do
 let(:instance) create :instance 

 before do
 get "/api/v2/#instance.slug/#type"
 end

 it 'responds with success status' do
 expect(last_response.status).to eq 200
 end
end

But today I tried to test the nested indexes. My issue is that the urls to tests are multiplied for the shared_examples so I can't use the same logic of doing the request in the before because last_response will be the last response (yes).

My first try was to loop through the urls in the it block like follow :

it 'responds with success status' do
 parent_types.each do |parent_type|
 get "/api/v2/#instance.slug/#parent_type/#instance.send(parent_type).first.uuid/#type"

 expect(last_response.status).to eq 200
 end
end

which does not work because the request is apparently not over when the expect is ran.

So my second try was to loop in the parent shared example and pass url as a variable :

RSpec.shared_examples 'nested_index' do
 context 'index without data' do
 it 'is nested in shows' do
 parent_types.each do |parent_type, parent_config|
 instance = create :instance, parent_config[:trait]

 url = "/api/v2/#instance.slug/#parent_type/#instance.send(parent_type).first.uuid/#type"
 it_behaves_like 'empty_nested_index', url
 end
 end
 end
end

but I get the error : it_behaves_like is not available from within an example. (e.g. an it block)

And I can't access the let variable if I'm not in an it block so I'm kind of stuck. Any tip on restructuring my tests would be appreciated.
