download_cats: Test generate_cats functionality (100% coverage) - keyboard_coop: Test keyboard_listener with mocked pynput (22% coverage) - mock_server: Test mitmproxy request interceptor (100% coverage) - random_jpg: Test JPEG generation with mocked Pillow (100% coverage) - randomize_numbers: Test random_digits functions (99% coverage) - scrape_website: Test scrape_comics with mocked requests (98% coverage) - split: Test text splitting utilities (100% coverage) - tag_divider: Test tag_divider with mock filesystem (44% coverage) - extract_links: Add HTML fixture for tests ---
