Testing Hidden Window Initialization Behavior in NW.js

This test suite validates the behavior of NW.js applications when the show:false window property is used, specifically checking for crash prevention. It uses Selenium WebDriver to automate Chrome browser testing and verify proper window initialization.

Test Coverage Overview

The test ensures proper handling of hidden window initialization in NW.js applications.

Verifies window creation with show:false property
Tests crash prevention mechanisms
Validates proper DOM element accessibility
Checks window state management

Implementation Analysis

The implementation uses Selenium WebDriver with Python to automate Chrome browser testing. The test leverages Chrome options to configure the NW.js application environment and implements implicit waits for reliable element detection.

Chrome WebDriver initialization with custom options
DOM element verification using find_element_by_id
Assertion-based success validation
Proper resource cleanup in finally block

Technical Details

Selenium WebDriver for browser automation
Chrome Options for NW.js app configuration
Environment variable usage for ChromeDriver path
Implicit wait timing of 5 seconds
Element content validation via innerHTML attribute

Best Practices Demonstrated

The test implements several testing best practices for reliable automation.

Proper exception handling and resource cleanup
Environment-independent path resolution
Explicit success criteria validation
Configurable browser automation setup
Defensive programming with try-finally block
