E-commerce & Payment Testing Automation

Automated end-to-end testing for e-commerce checkout flows and payment validation using Cypress with Page Object Model architecture.

📈 Business Impact

This test suite achieves 95% coverage of critical checkout paths (login, cart, checkout, payments), reducing manual regression testing time by 60% and catching edge cases before production deployment. Integrated with CI/CD to reduce hotfix frequency by 40% for development teams.

🎯 What This Project Tests

• Checkout Flows: Complete purchase workflows, cart management
• Payment Validation: Form validation, required fields, error handling
• Edge Cases: Multiple items, empty cart, checkout cancellation, invalid inputs
• User Experience: Login flows, continue shopping, order review, success confirmation
• Authentication: Valid/invalid login scenarios, locked users

🛠️ Tech Stack

• Cypress - E2E testing framework with Page Object Model (POM)
• JavaScript - Test scripting
• GitHub Actions - CI/CD automation with automated test gates
• Page Object Model - Scalable, maintainable test architecture
• Chrome/Electron - Test execution browsers
