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.:

const describeOnly = describe.only;
describeOnly.apply(describe);

The following patterns are considered warnings:

describe.only('foo', () => {});
it.only('foo', () => {});
describe['only']('bar', () => {});
it['only']('bar', () => {});
test.only('foo', () => {});
test['only']('bar', () => {});
fdescribe('foo', () => {});
fit('foo', () => {});
ftest('bar', () => {});
fit.each`
  table
`();
ftest.each`
  table
`();

These patterns would not be considered warnings:

describe('foo', () => {});
it('foo', () => {});
describe.skip('bar', () => {});
it.skip('bar', () => {});
test('foo', () => {});
test.skip('bar', () => {});
it.each()();
it.each`
  table
`();
test.each()();
test.each`
  table
`();
