# Disallow focused tests (no-focused-tests) Jest has a feature that allows you to focus tests by appending `.only` or prepending `f` to a test-suite or a test-case. This feature is really helpful to debug a failing test, so you don’t have to execute all of your tests. After you have fixed your test and before committing the changes you have to remove `.only` to ensure all tests are executed on your build system. This rule reminds you to remove `.only` from your tests by raising a warning whenever you are using the exclusivity feature. ## Rule Details This rule looks for every `describe.only`, `it.only`, `test.only`, `fdescribe`, `fit` and `ftest` occurrences within the source code. Of course there are some edge-cases which can’t be detected by this rule e.g.: ```js const describeOnly = describe.only; describeOnly.apply(describe); ``` The following patterns are considered warnings: ```js describe.only('foo', () => {}); it.only('foo', () => {}); describe['only']('bar', () => {}); it['only']('bar', () => {}); test.only('foo', () => {}); test['only']('bar', () => {}); fdescribe('foo', () => {}); fit('foo', () => {}); ftest('bar', () => {}); ``` These patterns would not be considered warnings: ```js describe('foo', () => {}); it('foo', () => {}); describe.skip('bar', () => {}); it.skip('bar', () => {}); test('foo', () => {}); test.skip('bar', () => {}); ```
