Testing MacOS Window Creation Crash Prevention in NW.js

This test suite validates the handling of window creation and crash scenarios in NW.js on macOS platforms. It specifically tests the application’s stability when creating new windows and verifies proper URL loading behavior.

Test Coverage Overview

The test coverage focuses on macOS-specific window handling and crash prevention in NW.js applications. Key functionality includes:

Platform-specific execution validation
Window handle management
URL loading verification
Crash prevention assessment

Implementation Analysis

The testing approach utilizes Selenium WebDriver to automate browser interactions and validate window behavior. The implementation employs Chrome options for NW.js app configuration and implements explicit wait patterns for reliable window handle verification.

Window switching logic
URL validation checks
Timeout handling
Cleanup procedures

Technical Details

Testing tools and configuration:

Selenium WebDriver with Chrome driver
Python test framework
Platform-specific conditionals
Custom NW.js utility functions
Environment variable configuration for ChromeDriver

Best Practices Demonstrated

The test implementation showcases several testing best practices for desktop application validation:

Proper exception handling and cleanup
Platform-specific test skipping
Explicit wait patterns
Clear assertion messages
Resource cleanup in finally block
