 # Mocking
 
-When writing tests it's only a matter of time before you need to create a "fake" version of an internal — or external — service. This is commonly referred to as **mocking**. Vitest provides utility functions to help you out through its **vi** helper. You can `import { vi } from 'vitest'` or access it **globally** (when [global configuration](/config/#globals) is **enabled**).

 ::: warning
 Always remember to clear or restore mocks before or after each test run to undo mock state changes between runs! See [`mockReset`](/api/mock#mockreset) docs for more info.
