# vitest/unbound-method

📝 Enforce unbound methods are called with their expected scope.

⚠️ This rule _warns_ in the 🌐 `all` config.

💭 This rule requires [type information](https://typescript-eslint.io/linting/typed-linting).

<!-- end auto-generated rule header -->

This rule extends the base [`@typescript-eslint/unbound-method`][original-rule]
rule, meaning you must depend on `@typescript-eslint/eslint-plugin` for it to
work. It adds support for understanding when it's ok to pass an unbound method
to `expect` calls.

### How to use this rule
