running-vitest-safely

Vitest hangs in CI when watch mode activates or tests lack timeouts. Prevent hanging Vitest processes by enforcing the --run flag, per-test timeouts, and hook timeouts for automated environments.

Run Vitest safely in automated environments by applying the --run flag to disable watch mode, setting per-test timeouts, and executing preflight checks to detect running processes and prevent duplicates.

Yes, you can use pnpm test to execute Vitest safely in local automation. This applies to unit test suites invoked via pnpm test, npm test, or vitest commands, enforcing safe execution with timeouts and optional bail.

The best way to stop duplicate Vitest processes is to run preflight checks that detect running Vitest processes before starting a new test run. This prevents duplicates and ensures safe process isolation.

Running Vitest without timeouts in Node allows hanging processes to consume resources indefinitely. Without enforced per-test timeouts and hook timeouts, automated test runs may fail to complete or block pipelines.
