Requirements Traceability And Test Cases

What is Requirements Traceability ?
Functional or software requirement specification  is the document which describes stakeholder's requirements which should be traced with deliverables produced during the software development life cycle.

What are the objectives of Requirements Traceeability ?
The objectives of requirement traceability, in general, are to

• Ensure that the deliverables meet the requirement specification.
• Ensure that no requirements are missed and therefore  that all are delivered.
• Identify which deliverables implement which requirements.
• Identify any deliverables that cannot be tracked back to a requirement. This may be either due to undocumented requirements or to the unnecessary introduction of features that are not actually required by the stakeholders.

Requirements Traceability and Test cases:
Every requirement should be traced to the individual test cases. This is required to ensure that all the requirements have been covered in the test cases and also to identify what tests are necessary to verify a particular requirement has been implemented successfully.
