globals

• Type: boolean
• Default: false
• CLI: --globals, --no-globals, --globals=false

By default, vitest does not provide global APIs for explicitness. If you prefer to use the APIs globally like Jest, you can pass the --globals option to CLI or add globals: true in the config.

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    globals: true,
  },
})

::: tip Note that some libraries, e.g., @testing-library/react, rely on globals being present to perform auto cleanup. :::

To get TypeScript working with the global APIs, add vitest/globals to the types field in your tsconfig.json:

{
  "compilerOptions": {
    "types": ["vitest/globals"]
  }
}

If you have redefined your typeRoots to include additional types in your compilation, you will need to add back the node_modules to make vitest/globals discoverable:

{
  "compilerOptions": {
    "typeRoots": ["./types", "./node_modules/@types", "./node_modules"],
    "types": ["vitest/globals"]
  }
}
