I have entities `User` and `Test`

```
@Entity
public class User {
    private Long id;
    private String userName;
}

@Entity
public class Test {
    private Long id;

    @ManyToMany
    private Set<User> users;
}

```

I can get all tests by User entity:

```
public interface TestRepository extends JpaRepository<EventSettings, Long> {
    List<Test> findAllByUsers(User user);
}

```

But which query can I use for finding all tests by `userName`?
