Testing SQLite Module Stability with Node 8 Integration in NW.js

This test suite validates the functionality of SQLite modules in NW.js on macOS environments, specifically addressing a crash issue with Node 8 integration. The test ensures database operations work correctly without system instability.

Test Coverage Overview

The test coverage focuses on SQLite module integration with NW.js on macOS platforms. Key functionality includes database query execution and crash prevention, with specific attention to platform compatibility and Node 8 integration points. Edge cases cover platform-specific behaviors and module loading scenarios.

Platform-specific execution checks
SQLite query validation
Crash prevention verification
Native module integration testing

Implementation Analysis

The testing approach combines Selenium WebDriver automation with native module installation verification. The implementation utilizes Chrome WebDriver for UI interaction and system-level checks for platform compatibility. Framework-specific features include:

Selenium WebDriver integration
Chrome Options configuration
Native module management
Platform-specific test skipping

Technical Details

Testing tools and configuration include:

Selenium WebDriver for browser automation
Chrome Options for NW.js app configuration
Python test runner
Platform detection utilities
Native module installation scripts
Environment-specific ChromeDriver setup

Best Practices Demonstrated

The test implementation showcases robust testing practices through proper resource management and error handling. Notable practices include:

Proper test cleanup with driver.quit()
Platform-specific test handling
Explicit wait management
Modular test organization
Clear assertion messaging
