FAQPage Schema
How do I run vitest in watch mode for specific test files?▼

You can run vitest in watch mode with file pattern filters to execute only matching tests. This provides instant, targeted feedback during test development by automatically re-running relevant tests when files change.

What is the best way to get instant feedback when refactoring existing tests?▼

The best way to get instant feedback when refactoring existing tests is using watch mode with focused pattern matching. This approach automatically re-runs only the tests matching your specific file or name patterns upon changes.

Can I filter jest watch mode to run only tests related to a new feature?▼

Yes, you can filter watch mode to run only tests related to a new feature using file pattern filters. This allows you to get rapid feedback on your changes without waiting for the entire test suite to complete.

Does focused watch mode work for debugging flaky tests?▼

Focused watch mode works for debugging flaky tests by continuously running only the targeted test patterns. It automatically re-runs the relevant tests on file changes, maintaining a fast feedback loop while you investigate instability.

Why use file pattern filters in watch mode instead of running the full test suite?▼

Using file pattern filters in watch mode isolates relevant tests, providing rapid feedback during development. Running the full test suite wastes time, whereas targeted pattern matching ensures only affected tests execute upon file changes.
