Testing Child Process Automation in NW.js

This test suite validates child process functionality in NW.js using Selenium WebDriver integration. It automates browser testing to verify proper execution and communication of child processes within the NW.js environment.

Test Coverage Overview

The test coverage focuses on validating child process behavior in NW.js through automated browser testing.

Verifies successful child process execution
Tests process communication and result handling
Validates Chrome WebDriver integration
Ensures proper environment setup and cleanup

Implementation Analysis

The implementation utilizes Selenium WebDriver with Python to automate Chrome-based testing of NW.js child processes.

Key patterns include:

Chrome options configuration for NW.js app testing
Implicit wait handling for async operations
Element content verification using wait_for_element_id_content
Try-finally block for proper driver cleanup

Technical Details

Selenium WebDriver for browser automation
Chrome Options for NW.js app configuration
Python standard libraries (os, sys, time)
Custom nw_util helper functions
ChromeDriver executable path configuration

Best Practices Demonstrated

The test implementation showcases robust automated testing practices for desktop applications.

Proper resource cleanup in finally block
Dynamic test directory path handling
Explicit assertion checking
Modular test utility functions
Configurable browser options
