Testing Mixed Context Window Handling in NW.js

This test suite validates mixed context handling in NW.js applications using Selenium WebDriver. It specifically tests the interaction between different window contexts and object rendering behaviors.

Test Coverage Overview

The test coverage focuses on verifying window handling and object rendering in mixed contexts.

Key areas tested include:

Window spawning and handle management
Object rendering in new windows
Context switching between multiple windows
Element attribute verification

Implementation Analysis

The implementation uses Selenium WebDriver to automate browser interactions and validate mixed context behaviors. The test leverages Chrome options for NW.js app testing and implements explicit window handle management.

Key patterns include:

Dynamic path configuration for test resources
WebDriver initialization with custom Chrome options
Explicit window handle switching
Element interaction and attribute verification

Technical Details

Testing tools and configuration:

Selenium WebDriver for browser automation
Chrome Options for NW.js app configuration
Custom utility functions from nw_util
Environment-based ChromeDriver path
Try-finally block for proper resource cleanup

Best Practices Demonstrated

The test demonstrates robust automation practices for complex UI testing scenarios.

Notable practices include:

Proper resource cleanup with driver.quit()
Explicit waits for window handles
Clear separation of setup and test logic
Error handling with try-finally blocks
Modular test utility integration
