library3.1.0jsnpmunverified

ESLint plugin providing formatting rules for Jest test suites, version 3.1.0 (supports ESLint 8.x). It enforces consistent padding (blank lines) around test blocks like describe, test, after-all, etc. Most rules are auto-fixable. Differentiators: focused solely on formatting (not linting logic), with recommended and strict config presets. Release cadence is sporadic; last major was v3.0.0 with breaking changes. Active maintenance status.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

plugin

✓ plugins: ['jest-formatting']

✗ plugins: ['eslint-plugin-jest-formatting']

ESLint automatically strips the eslint-plugin- prefix for plugin references.

recommended config

✓ extends: ['plugin:jest-formatting/recommended']

✗ extends: ['jest-formatting/recommended']

Must include the plugin: prefix when referencing configs.

strict config

✓ extends: ['plugin:jest-formatting/strict']

✗ extends: ['jest-formatting']

Strict config enables all rules; plain 'jest-formatting' is invalid.

Configures ESLint to enforce padding around describe and test blocks in Jest files.

// .eslintrc.json { "plugins": ["jest-formatting"], "rules": { "jest-formatting/padding-around-describe-blocks": 2, "jest-formatting/padding-around-test-blocks": 2 } } // test file example describe('suite', () => { beforeEach(() => { jest.clearAllMocks(); }); it('test', () => { expect(true).toBe(true); }); });
