# Enforce unbound methods are called with their expected scope (`unbound-method`) 💭 This rule requires type information. ## Rule details 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. See the [`@typescript-eslint` documentation][original-rule] for more details on the `unbound-method` rule. Note that while this rule requires type information to work, it will fail silently when not available allowing you to safely enable it on projects that are not using TypeScript. ## How to use ```json5 { parser: '@typescript-eslint/parser', parserOptions: { project: 'tsconfig.json', ecmaVersion: 2020, sourceType: 'module', }, overrides: [ { files: ['test/**'], plugins: ['jest'], rules: { // you should turn the original rule off *only* for test files '@typescript-eslint/unbound-method': 'off', 'jest/unbound-method': 'error', }, }, ], rules: { '@typescript-eslint/unbound-method': 'error', }, } ``` This rule should be applied to your test files in place of the original rule, which should be applied to the rest of your codebase. ## Options See [`@typescript-eslint/unbound-method`][original-rule] options (e.g. `ignoreStatic`).
