# Disallow identical titles (`no-identical-title`)
|
||
|
|
|
||
|
|
Having identical titles for two different tests or test suites may create
|
||
|
|
confusion. For example, when a test with the same title as another test in the
|
||
|
|
same test suite fails, it is harder to know which one failed and thus harder to
|
||
|
|
fix.
|
||
|
|
|
||
|
|
## Rule Details
|
||
|
|
|
||
|
|
This rule looks at the title of every test and test suites. It will report when
|
||
|
|
two test suites or two test cases at the same level of a test suite have the
|
||
|
|
same title.
|
||
|
|
|
||
|
|
The following patterns are considered warnings:
|
||
|
|
|
||
|
|
```js
|
||
|
|
describe('foo', () => {
|
||
|
|
it('should do bar', () => {});
|
||
|
|
it('should do bar', () => {}); // Has the same title as the previous test
|
||
|
|
|
||
|
|
describe('baz', () => {
|
||
|
|
// ...
|
||
|
|
});
|
||
|
|
|
||
|
|
describe('baz', () => {
|
||
|
|
// Has the same title as a previous test suite
|
||
|
|
// ...
|
||
|
|
});
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
These patterns would not be considered warnings:
|
||
|
|
|
||
|
|
```js
|
||
|
|
describe('foo', () => {
|
||
|
|
it('should do foo', () => {});
|
||
|
|
it('should do bar', () => {});
|
||
|
|
|
||
|
|
// Has the same name as a parent test suite, which is fine
|
||
|
|
describe('foo', () => {
|
||
|
|
// Has the same name as a test in a parent test suite, which is fine
|
||
|
|
it('should do foo', () => {});
|
||
|
|
it('should work', () => {});
|
||
|
|
});
|
||
|
|
|
||
|
|
describe('baz', () => {
|
||
|
|
// Has the same title as a previous test suite
|
||
|
|
// Has the same name as a test in a sibling test suite, which is fine
|
||
|
|
it('should work', () => {});
|
||
|
|
});
|
||
|
|
});
|
||
|
|
```
