### Examples

Examples of **correct** code for this rule:

```js
import { getData } from '../../model/selectors/getData'
import { Component } from 'entities/Component'

// With option: alias: '@'
import { Component } from '@/entities/Component'

// With option: testFilesPatterns: ['**/*.test.*']
// File path C:/Users/project/src/entities/Component/file.test.ts
import { Component } from 'entities/Component/testing'

// File path 'C:/Users/project/src/widgets/Profile/model/selectors/getUserProfile.ts',
import { getUser } from 'entities/User'

// With option: alias: '@'
// File path 'C:/Users/project/src/widgets/Profile/model/selectors/getUserProfile.ts',
import { getUser } from '@/entities/User'
```

Examples of **incorrect** code for this rule:

```js
import { Some } from 'entities/Component/model/some.ts'
// Error: Absolute import is allowed only from public API (index.js/ts)

// With option: alias: '@'
import { Some } from '@/entities/Component/model/some.ts'
// Error: Absolute import is allowed only from public API (index.js/ts)

// With option: testFilesPatterns: ['**/*.test.*']
// File path C:/Users/project/src/entities/Component/file.test.ts
import { Some } from 'entities/Component/testing/some.ts'
// Error: Absolute import is allowed only from public API (index.js/ts)

// With option: testFilesPatterns: ['**/*.test.*']
// File path C:/Users/project/src/entities/Component/forbidden.ts
import { Some } from 'entities/Component/testing'
// Error: Test data need import from public API file for tests (testing.js/ts) only in files from testFilesPatterns option

// File path 'C:/Users/project/src/widgets/Profile/model/selectors/getUserProfile.ts',
import { getUser } from '../../../../entities/User/model/selectors/getUser/getUser'
// Error: Must be imported from a public API file (index.js/ts)
