- 1. Software Testing & Quality Assurance Prof. Dr. Tariq Javid Graduate School of Engineering Sciences & Information Technology Faculty of Engineering Sciences & Technology Hamdard University Spring 2024
- 3. 3 Introduction • Requirements Management • Traceability • Requirements Traceability Matrix
- 4. 4
- 5. 5 Requirements Management • Process of identifying, analyzing, documenting, and tracking software requirements throughout the development and testing • To ensure software meet customer and user needs • To ensure testing is focused on verifying, validating requirements
- 6. 6 Traceability • Ability to trace software requirements to specific test cases, code modules, and other project artifacts • To ensure software meets specified requirements • To ensure changes to requirements are properly assessed and implemented
- 7. 7 Challenge in Tracking Project Requirements • Tracking project requirements can be challenging • High depending on development environment • Some projects may have a few requirements • Some projects may have dozens or even more requirements
- 8. 8 Requirements for Software Development • Types of requirements should be considered for software development • Business requirements • User requirements • UI requirements • Functional and nonfunctional requirements • Technical requirements https://www.simplilearn.com/project-management-and-the-requirements-traceability-matrix-article#what_is_a_traceability_matrix
- 9. 9 Effective Requirements Management • Reduce defects and errors • Improve software quality • Increase customer satisfaction • Reduce development time and costs
- 10. 10 Why Traceability? • Ensure requirements are accurately implemented • Verify that tests cover all requirements • Identify and address defects and errors early • Manage changes to requirements and assess their impact on software
- 11. 11 Best Practices • Use requirements management tool to document and track requirements • Develop requirements traceability matrix to trace requirements to test cases and code modules • Involve stakeholders in requirements analysis and prioritization • Verify, validate requirements throughout development, testing process • Use agile methodologies to iteratively develop and test software
- 13. 13 Tools • DOORS, TestLink, Jama Connect • Traceability Matrix, Requirements Traceability Tool, Case Traceability Tool • Jira, Trello, Asana
- 14. 14 Example: Requirements Traceability Matrix Requirement ID Requirement Description Test Case ID Test Case Description Code Module Status REQ-001 User shall be able to login with valid credentials TC-001 Valid login credentials Login.java Implemented REQ-002 User shall be able to view dashboard after login TC-002 Dashboard display after login Dashboard.jsp Implemented REQ-003 User shall be able to create new account TC-003 New account creation CreateAccount.java In Progress REQ-004 User shall be able to edit existing account information TC-004 Edit account information EditAccount.jsp Not Started REQ-005 User shall be able to delete account TC-005 Account deletion DeleteAccount.java Not Started
- 15. 15 Types of Traceability Matrix • Forward Traceability … Mapping Requirements to Test Cases • Backward Traceability … Mapping Test Cases to Requirements • Bidirectional Traceability
- 16. 16 Forward Traceability • Forward traceability is used to map the requirements to the test cases • Not only will this establish that every requirement is being tested from top to bottom, but it will also assist in confirming that a project’s trajectory is sound
- 17. 17 Backward Traceability • You can make a backward traceability matrix by mapping test cases with the requirements • Doing so aids you in avoiding “scope creep” and going beyond the initial requirements unnecessarily
- 18. 18 Bidirectional Traceability • Bidirectional traceability essentially combines forward and backward traceability into one document • This type is useful because it establishes that each requirement has relating test cases
