Testing Window Management and HTTP Request Handling in NW.js

This test suite validates window handling and HTTP request functionality in NW.js applications using Selenium WebDriver. It specifically tests the ability to open and close windows while maintaining proper HTTP communication.

Test Coverage Overview

The test suite covers critical window management operations and HTTP request handling in NW.js.

Key areas tested include:

Window opening and closing operations
HTTP server communication verification
Window handle state management
Request success validation after window operations

Implementation Analysis

The implementation utilizes Selenium WebDriver with Python to automate browser interactions and validate window behaviors.

Key patterns include:

Dynamic port allocation for HTTP server
Template-based HTML content generation
Explicit wait conditions for window handles
Chrome WebDriver configuration with NW.js specific options

Technical Details

Testing tools and configuration:

Selenium WebDriver with Chrome options
Python HTTP server for request testing
Custom utility functions for window handle management
Template-based test page generation
Mixed-context mode configuration
ChromeDriver with verbose logging

Best Practices Demonstrated

The test demonstrates robust testing practices for desktop applications.

Notable practices include:

Proper resource cleanup in finally block
Dynamic port allocation to prevent conflicts
Implicit wait implementation for stability
Modular test page template approach
Comprehensive error logging setup
