Testing MacOS Window Close Crash Prevention in NW.js

This test suite validates application window closing behavior on macOS platforms using Selenium WebDriver, specifically focusing on crash prevention during window closure operations. The test ensures proper cleanup and memory management when closing NW.js application windows on Mac systems.

Test Coverage Overview

The test coverage focuses on platform-specific window closing functionality for macOS environments.

Key areas tested include:

Platform-specific execution control
Window close button interaction
Post-closure element verification
Crash prevention validation

Implementation Analysis

The testing approach utilizes Selenium WebDriver with Chrome options for automated UI interaction testing. The implementation employs platform detection for Mac-specific execution and incorporates explicit element verification through DOM queries.

Key patterns include:

Platform-specific test filtering
WebDriver session management
Element interaction verification
Proper resource cleanup

Technical Details

Testing tools and configuration:

Selenium WebDriver for browser automation
Chrome Options for NW.js app configuration
Platform module for OS detection
Environment variable integration for ChromeDriver path
Try-finally block for resource management

Best Practices Demonstrated

The test demonstrates robust testing practices for desktop application automation.

Notable practices include:

Platform-specific test isolation
Proper exception handling
Resource cleanup in finally block
Explicit assertion validation
Environment-aware configuration
