How to import the additional exports (components, mixins etc)?

In `src/index.js` file, we do:
```
// Expose the components
export {
Test,
/* -- Add more components here -- */
}
```
How can the user import that Test in his own app? The code below results with `"export 'Test' was not found in 'somewhere'`
```
import { Test } from 'somewhere'
```
