"""
Unit tests for website crawling functionality.

This module tests the core website crawling features including:
- URL crawling logic with different providers
- Robots.txt respect and compliance
- Max depth limiting for crawl operations
- Content extraction from web pages
- Link following logic and navigation

The tests cover multiple crawl providers (Firecrawl, WaterCrawl, JinaReader)
and ensure proper handling of crawl options, status checking, and data retrieval.
