Summary

• run PostgreSQL tests in a single Jest process
• route PostgreSQL CI through the shared test:postgres script
• keep non-PostgreSQL tests parallel

Why

The integration files share one PostgreSQL-backed outbox. With Jest workers running in parallel, a worker can consume another worker's outbox message. The process-local DeleteAttachment waiter then times out even though the message was dispatched and the outbox is empty.

Validation

• PostgreSQL integration tests on Node.js 22 — passed in CI
• PostgreSQL integration tests on Node.js 24 — passed in CI
• npm test -- --runInBand --testPathPatterns=tests/unit — 114 tests passed
• npm run test:postgres -- --showConfig — runInBand: true, maxWorkers: 1
• Prettier check for package.json and .github/workflows/test.yml

No substantive issues found. The workflow now consistently uses the serialized PostgreSQL test script while leaving the default test path parallel.

Prevent PostgreSQL Integration Test Races with Serial Execution

Bug Fix

🐛 Run PostgreSQL integration suites in a single Jest process to prevent shared outbox messages from being consumed by competing workers. Non-PostgreSQL test suites remain parallel.

Changes

• package.json: Updated test:postgres to use Jest’s --runInBand option, ensuring PostgreSQL tests execute serially.
• .github/workflows/test.yml: Routed PostgreSQL integration tests through the shared test:postgres script so CI consistently applies the serial execution configuration.

Validation

• PostgreSQL integration suites passed in CI on Node.js 22 and 24.
• All 114 unit tests passed with serial execution.
• Jest configuration confirmed runInBand: true and maxWorkers: 1.
• Prettier checks passed for the modified files.
