Command Line Interface

Commands

vitest watch

Run all test suites but watch for changes and rerun tests when they change. Same as calling vitest without a command. In CI environments this command will fallback to vitest run

vitest run

Perform a single run without watch mode.

vitest dev

Run vitest in development mode.

Run only tests that cover a list of source files. Works with static lazy imports, but not the dynamic ones. All files should be relative to root folder.

Useful to run with lint-staged or with your CI setup.
