Testing Window Navigation State Preservation in NW.js

This test suite validates window navigation behavior in NW.js applications using Selenium WebDriver. It specifically tests the preservation of window state and event handling across navigation actions.

Test Coverage Overview

The test ensures proper window handling and navigation in NW.js applications.

Key areas covered include:

Window state preservation during navigation
Event handler persistence across page loads
Button click event handling
Navigation through anchor tags

Implementation Analysis

The test utilizes Selenium WebDriver with Chrome options configured for NW.js testing.

Implementation features:

Chrome WebDriver integration with custom options
Implicit wait handling for element loading
DOM element interaction validation
Assertion-based success 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 configuration
Try-finally block for proper driver cleanup

Best Practices Demonstrated

The test exemplifies robust automation practices with proper resource management and error handling.

Notable practices:

Proper driver initialization and cleanup
Explicit element waiting strategies
Clear assertion conditions
Modular test structure with utility imports
Environment-aware configuration
