[S6] Write tests for PR validation and scheduled reconciliation #66
Description
Description
Test suites for PR validation flow and cron-based reconciliation.
PR Validation Tests
- PR with valid config change → passing check
- PR with invalid config → failing check with details
- PR without config change → no check run
- PR with both root and .github/ config → warning in check
Scheduled Reconciliation Tests
- Cron fires and processes all active repos
- Rate limit backoff is triggered when remaining is low
- Staggered job timing
- Inactive installations/repos are skipped
Acceptance Criteria
- All test scenarios covered
- Rate limit behavior tested
- Tests are deterministic and fast
