- 1. Testing & Quality Assurance in Software Development Effective quality assurance is the backbone of reliable software. It ensures products meet standards and function as intended. In this presentation, we'll explore QA practices that make the difference between software that shines and software that fails. by Ozías Rondón
- 2. What is Software Quality Assurance? Definition A systematic process that ensures products and services meet specified requirements and quality standards. Purpose To identify and fix defects early in development, preventing costly issues later. Scope Covers all aspects of software development, from requirements to deployment and maintenance.
- 3. The Role of QA in Software Development 1 Improved ROI Lower maintenance costs 2 Enhanced User Experience Greater satisfaction and loyalty 3 Defect Prevention Catching issues before release Quality Assurance isn't just about finding bugs. It's about preventing them through systematic processes throughout development.
- 4. Types of Software Testing Unit Testing Testing individual components in isolation to verify they work as expected. Integration Testing Ensuring multiple components work together properly when combined. System Testing Validating the entire application against specified requirements. Acceptance Testing Determining if the software meets business requirements and user needs.
- 5. Functional vs. Non-Functional Testing Functional Testing • Verifies specific functions work as expected • Tests user interfaces and APIs • Focuses on features and behaviors • Examples: regression, smoke testing Non-Functional Testing • Assesses operational aspects • Evaluates system performance under load • Tests security vulnerabilities • Examines usability and accessibility
- 6. Manual vs. Automated Testing Aspect Manual Testing Automated Testing Speed Slower, labor-intensive Faster, efficient for repetition Cost Higher long-term cost Higher initial investment Human Insight Strong for UX issues Limited creative assessment Best For Exploratory testing Regression and load testing
- 7. Test Planning and Strategy Define Objectives Establish clear goals for testing based on requirements and risks. Create Test Cases Develop detailed scenarios covering all critical paths and edge cases. Prioritize Efforts Focus on high-risk, high-impact features first for maximum efficiency. Allocate Resources Assign appropriate time, tools, and personnel to testing activities.
- 8. Test Execution and Reporting Execute Tests Run planned test cases systematically 1 Record Results Document outcomes with evidence 2 Analyze Findings Evaluate pass/fail patterns 3 Report to Stakeholders Communicate insights clearly 4 Effective reporting transforms test data into actionable intelligence for the development team.
- 9. Defect Management 1 Identify Discover and document defects with detailed reproduction steps. 2 Categorize Classify by severity, priority, and affected components. 3 Assign Delegate to appropriate team members for resolution. 4 Verify Retest fixed issues to confirm proper resolution.
- 10. Continuous Integration and Testing Automated Builds Code changes trigger automatic build processes to detect integration issues early. Automated Tests Tests run automatically with each build to provide immediate feedback. Instant Feedback Developers receive immediate alerts about build or test failures.
- 11. Test-Driven Development (TDD) Write Test Create tests that define expected functionality before writing code. 1 Run Test Execute the test, which will fail initially. 2 Write Code Develop minimum code needed to pass the test. 3 Refactor Improve code quality while ensuring tests still pass. 4
- 12. Performance Testing Load Testing Evaluates system behavior under expected user loads to identify bottlenecks. Stress Testing Pushes systems beyond normal capacity to determine breaking points. Scalability Testing Assesses how effectively the system scales with increasing loads.
- 13. Security Testing Vulnerability Assessment Systematic review identifying security weaknesses in applications. Scans detect common exploits and configuration issues. Penetration Testing Ethical hackers attempt to breach systems. Simulates real-world attacks to find exploitable vulnerabilities. Compliance Checks Verifies software meets industry regulations. Ensures adherence to standards like GDPR, HIPAA, or PCI DSS.
- 14. User Acceptance Testing (UAT) 1 Prepare Test Environment Setup production-like systems 2 Train End Users Equip users with testing knowledge 3 Execute Test Cases Users validate real-world scenarios 4 Collect & Implement Feedback Address user concerns before release
- 15. Mobile App Testing Device Fragmentation Testing across various screen sizes, resolutions, and hardware configurations is essential. OS Version Compatibility Apps must work across multiple Android and iOS versions still in use. Network Conditions Testing under varying connection states ensures reliability in real-world scenarios. Battery & Resource Usage Apps should minimize power consumption and memory usage for optimal performance.
- 16. Best Practices in QA Early QA Involvement Include QA from the requirements gathering phase to prevent design defects. Cross- Functional Collaboration Foster partnership between developers and testers to enhance quality awareness. Continuous Improvement Regularly update skills and refine processes based on project retrospectives.
- 17. Tools for QA and Testing Modern QA relies on specialized tools for test management, automation, and defect tracking to increase efficiency and coverage.
- 18. Measuring QA Success Before QA Improvements After QA Improvements
- 19. The Future of QA 1 AI-Powered Testing Machine learning algorithms will identify patterns and predict defects before they occur. 2 Shift-Left Approach Testing will begin earlier in development cycles, with developers taking on more testing responsibility. 3 DevOps Integration QA practices will seamlessly blend with development and operations in unified workflows. 4 Intelligent Test Automation Self-healing test scripts will adapt to UI changes without manual intervention.
