# 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', () => {});
|
|||
|
|
fit.each`
|
|||
|
|
table
|
|||
|
|
`();
|
|||
|
|
ftest.each`
|
|||
|
|
table
|
|||
|
|
`();
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
These patterns would not be considered warnings:
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
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
|
|||
|
|
`();
|
|||
|
|
```
