Benedikt Willi fab66d1528 Implement Jinja2 templates for startpage and error pages
Features:
- Add Jinja2 template engine for page rendering
- Create startpage with Bowser branding and version info
- Create error page templates for 404, 500, and network errors
- Support for about:startpage special URL
- Custom error message support in templates
- Graceful fallback rendering if template fails
- Browser now starts with startpage when no URL provided

Templates:
- assets/pages/startpage.html - Beautiful purple gradient intro page
- assets/pages/error_404.html - Pink gradient 404 error page
- assets/pages/error_500.html - Red gradient 500 error page
- assets/pages/error_network.html - Orange gradient network error page

Code:
- src/templates.py - Template rendering utilities with Jinja2
- Updated main.py to use startpage as default
- Updated Frame.load() to handle about: URLs and render errors with templates
- Added 7 comprehensive template tests

All 62 core tests passing (excluding GTK-dependent tests)

Test Organization

  • test_url.py - URL parsing and resolution
  • test_parser.py - HTML/CSS parsing
  • test_browser.py - Browser and tab management
  • test_cookies.py - Cookie jar functionality
  • test_layout.py - Layout engine components

  • conftest.py - Shared fixtures and configuration

Writing Tests

Tests use pytest. Example:

def test_feature():
    # Arrange
    obj = MyClass()
    
    # Act
    result = obj.method()
    
    # Assert
    assert result == expected

Use mocks for GTK components:

@patch('src.browser.browser.Gtk')
def test_with_gtk(mock_gtk):
    browser = Browser()
    # test code
