Software Testing & QA
Expert Insights
• Human testers execute test cases manually
• Best for exploratory, usability, and ad-hoc testing
• Ideal for user experience validation
• More flexible for changing requirements
Automated Testing:
• Scripts execute test cases automatically
• Perfect for regression, load, and repetitive testing
• Faster execution and higher accuracy
• Better ROI for stable, frequently tested features
We recommend a balanced approach combining both methods for optimal coverage.
