Summary by CodeRabbit

  • Bug Fixes

    • Improved integration test reliability by detecting occupied ports and service startup failures earlier.
    • Added extended timeouts for ClickHouse-related integration tests to support slower environments.
  • Chores

    • Updated CI setup to pull the required ClickHouse image automatically.
    • Made test worker restart behavior configurable, with CI configured to avoid automatic restarts.

Integration Test Stability

Layer / File(s) Summary
CI test environment configuration
.github/workflows/ci.yaml, Makefile
CI pulls the configured ClickHouse image. Integration tests use configurable pytest worker restarts and disable restarts in CI.
ClickHouse integration timeouts
plugins/nemo-evaluator/tests/integration/conftest.py, services/intake/tests/integration/test_local_clickhouse_provisioning.py
ClickHouse-dependent tests use a 600-second pytest timeout.
Platform startup checks
plugins/nemo-evaluator/tests/integration/test_publish_to_intake.py
The platform fixture checks for occupied ports before startup. Readiness polling reports the process exit code when startup fails early.

Suggested labels: chore

Suggested reviewers: htolentino-nvidia, a2bondar

Mergeability Score: 🟡 Moderate · up to f02e5

The integration-test setup can bind the service on one port while checking readiness on another when BASE_URL omits a port, causing tests to fail or wait incorrectly. This bounded correctness issue should be fixed before merge.

- Around line 147-151: Update the fixture around BASE_URL and running_platform
so a portless BASE_URL is rejected before startup, matching running_platform’s
validation, rather than defaulting the bind check to 8080 while readiness
polling uses the scheme default port.

Keep the bind port and readiness URL consistent.

When BASE_URL has no explicit port, the fixture binds to 8080, but readiness polling uses the scheme default port. Reject portless URLs, as running_platform does, or normalize BASE_URL before starting the platform.
