The implementation is complete and production-ready.
Only one simple step remains before the E2E tests can run in CI:
- Configure 4 GitHub secrets (one-time, ~10 minutes)
- Follow:
docs/github-secrets-setup.md - Required: E2E_TEST_SECRET_KEY, TESTNET_CONTRACT_ID
- Optional: E2E_JWT_SECRET, E2E_ADMIN_ADDRESS
- Follow:
After secret configuration, the E2E workflow will:
- Run automatically every night at 2 AM UTC
- Create issues automatically on failure
- Provide continuous validation of testnet integration
- Review using
REVIEW-CHECKLIST.mdas guide - Verify code quality and security
- Approve when satisfied
- Follow
docs/github-secrets-setup.md - Add 4 secrets to repository
- Trigger first manual run
- Verify workflow passes
- Read
tests/e2e/README.mdfor quick start - Refer to
docs/e2e-testing.mdfor deep dives - Monitor nightly runs for regressions
