## Project Structure

### Main Classes

- **UserService**: A service class that simulates API calls to fetch user details and user posts. It includes methods to fetch a user and their posts with simulated network delays.

### Data Classes

- **User**: Represents a user with an ID and a name.

- **UserPosts**: Represents a user's posts with a user ID and a list of posts.

- **EnrichedUser**: Represents an enriched user with user details and their posts.

### Test Classes

- **UserServiceTest**: A test class that uses Kotest to test the `UserService` class. It includes a test case to verify the generation of user IDs and concurrent processing of users with `parMap`.
