 Vitest allows you to write tests for your types, using `expectTypeOf` or `assertType` syntaxes. By default all tests inside `*.test-d.ts` files are considered type tests, but you can change it with [`typecheck.include`](/config/#typecheck-include) config option.
 
 Under the hood Vitest calls `tsc` or `vue-tsc`, depending on your config, and parses results. Vitest will also print out type errors in your source code, if it finds any. You can disable it with [`typecheck.ignoreSourceErrors`](/config/#typecheck-ignoresourceerrors) config option.
