Testing Window Navigation and Object Handling in NW.js

This test suite validates window navigation and object handling in NW.js applications using Selenium WebDriver. The test verifies proper window switching, element interactions, and event handling across multiple browser windows.

Test Coverage Overview

The test provides comprehensive coverage of window management and DOM interactions in NW.js applications.

Window handle switching between parent and child windows
Element interaction across multiple windows
Event propagation validation
Window closure handling and cleanup

Implementation Analysis

The test implements a Selenium WebDriver approach using Python to automate browser interactions.

Chrome WebDriver configuration with NW.js specific options
Window handle management using switch_to_window
DOM element selection and interaction
Assertion-based result validation

Technical Details

Selenium WebDriver with Chrome driver
Python test implementation
Chrome Options configuration for NW.js
Implicit wait timing configuration
HTML element interaction via tag name and ID selectors

Best Practices Demonstrated

The test exemplifies robust automation practices for window-based testing.

Proper resource cleanup in finally block
Explicit window handle management
Strategic wait implementation
Clear assertion patterns
Error handling with try-finally structure
