Author: igmarin

Service object testing patterns for rspec-service-testing skill.

Unit test for service object

frozen_string_literal: true

RSpec.describe Users::SyncService, type: :unit do describe '.call' do it 'returns success and creates records' do user = build(:user) result = Users::SyncService.call(user: user) expect(result[:success]).to be true expect(result[:response]).to include(:synced_count) end end end

Error handling spec

RSpec.describe Users::SyncService, type: :unit do it 'returns error shape when external API fails' do allow(ExternalApi).to receive(:push).and_raise(Net::OpenTimeout) result = Users::SyncService.call(user: create(:user)) expect(result[:success]).to be false expect(result[:response][:error]).to match(/timeout/i) end end

Integration-style spec using perform_enqueued_jobs for background jobs

RSpec.describe 'Sync integration', type: :integration do it 'enqueues and performs SyncUserJob' do user = create(:user) expect { SyncUserJob.perform_later(user.id) }.to have_enqueued_job(SyncUserJob) perform_enqueued_jobs # assert side effects end end
