Service Testing Checklist
- Show RED/GREEN proof before implementation:
- focused command
- expected RED failure reason
- focused GREEN rerun
- broader
bundle exec rspec spec/services/check when available
- Write unit tests for service public API (.call)
- Verify error shapes for failures (result[:success] == false)
- Use doubles for network/3rd-party calls and assert they were invoked correctly
- Add integration specs for background job orchestration when relevant
- Ensure time-dependent code uses travel_to in specs
- Use
perform_enqueued_jobsandhave_enqueued_jobmatchers for job assertions - Keep tests focused and fast; avoid full-stack integration when unit suffices
