Testing macOS Progress Bar Crash Prevention in NW.js

This test suite validates the setProgressBar functionality on macOS platforms using Selenium WebDriver, specifically addressing a potential crash issue (#6143) in NW.js. The test ensures stable progress bar updates without application crashes.

Test Coverage Overview

The test provides targeted coverage for macOS-specific progress bar functionality, focusing on crash prevention.

Key areas covered:

Platform-specific execution on macOS
Progress bar state management
Crash prevention verification
System stability monitoring

Implementation Analysis

The implementation utilizes Selenium WebDriver with Chrome options to automate the test scenario.

Key patterns include:

Platform-specific test filtering
WebDriver initialization with custom NW.js app path
Implicit wait handling
Result verification through DOM element inspection

Technical Details

Testing tools and configuration:

Selenium WebDriver for automation
Chrome Options for NW.js app configuration
Platform detection using Python’s platform module
Environment variable integration for ChromeDriver path
Timeout management with implicit waits

Best Practices Demonstrated

The test demonstrates robust error handling and platform-specific testing practices.

Notable implementations:

Proper test cleanup with driver.quit()
Platform-specific test skipping
Try-finally block for resource management
Clear success criteria definition
Explicit wait handling for stability
