# 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', () => {});
});
});
```
