Testing Browser Window Management Implementation in teamcapybara/capybara

This test suite validates Capybara’s window management functionality, specifically focusing on opening and managing new browser windows during test execution. The specs ensure proper window creation, switching, and content manipulation capabilities.

Test Coverage Overview

The test suite covers essential window management operations in Capybara, including opening new windows and manipulating their content.

Tests blank window creation with default URL and title
Verifies window content manipulation capabilities
Handles window cleanup and proper session management
Ensures proper window switching functionality

Implementation Analysis

The testing approach utilizes Capybara’s window management API to validate browser window operations. The implementation employs before/after hooks for setup and cleanup, with explicit window state management.

Key patterns include:

Session-based window tracking
Window state verification
Content manipulation validation
Proper window cleanup procedures
