Requirement traceability and its impotrance

In many organization testing starts after the execution/coding phase of the project.If the organization wants to really get benefits from testing,then tester should get involved right from the beginning of the requirement phase.

If the tester get involved right from the requirement phase ,then requirement traceability is one of the important report that can detail what kind of test coverage the testcase have.

The following figure shows how we can measure the test coverage using the requirement traceability. we have extracted the important functionality from the requirement document and aligned it on the left hand side of the document.on the other side on the top we have mapped the test cases with the requirement.with this we can ensure the all the requirements are covered by our test cases.
