Software Testing & QA
Expert Insights

Manual Testing:
• 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.

QA should begin from day one of development:
Requirements Phase: Review and validate requirements for testability
Design Phase: Create test plans and identify test scenarios
Development Phase: Implement unit tests and continuous testing
Integration Phase: Conduct integration and system testing
Pre-Release: Perform UAT, performance, and security testing
Post-Release: Monitor production and conduct regression testing

Early QA involvement reduces defect costs by up to 100x compared to post-production fixes.

Our comprehensive coverage approach includes:
Requirements Traceability: Map all requirements to test cases
