FAQPage Schema

How do I profile slow tests in a Vitest monorepo?▼

To profile slow tests in a Vitest monorepo, run a diagnostics script that executes per-file test profiling to detect slow, hanging, and failing test runs. This surfaces performance bottlenecks and flaky tests for triage.

What is the best way to detect flaky tests across a monorepo?▼

Detecting flaky tests across a monorepo requires running per-file diagnostics that identify hanging and failing tests. This approach surfaces timeouts and reliability issues, providing quick triage guidance to prioritize fixes.

How do I identify which test files are causing CI pipeline bottlenecks?▼

Identify CI pipeline bottlenecks by profiling all test files individually to detect slow, hanging, and failing tests. The generated test-health report highlights performance bottlenecks and flaky tests for targeted fixes.

Can I use this test profiling approach with existing Vitest workflows?▼

Yes, this test profiling approach works directly with Vitest-based workflows across monorepos and CI pipelines. It implements a script that runs per-file diagnostics without requiring additional dependencies.

How do I generate a test-health report for triage and fixes?▼

Generate a test-health report by running the diagnostics script on your repository. The script profiles all test files to surface flaky tests, timeouts, and performance bottlenecks, providing quick triage guidance to prioritize fixes.
