It is a document which helps Test/Development Managers to gain the confidence about the testing coverage. Using this matrix we can trace all the requirements with the lower entities such as Test Scenarios and Test cases. And this is not just saying – we can map Business Requirements with the Functional requirements followed by Test Scenarios and Test Cases which can be again mapped with the defect.
BR <--> FR <--> Test Scenario <--> TestCase <-->Defect
- Less Defect Leakage
- Best coverage of the requirements in the Test cases
- Ensures that developers are not creating some features which is not at all in the requirement
- Best tracking of the changes in the requirements
- There may a case when extra functionality is delivered to the customer which was not specified in the requirements.
The best thing – if you know any off these BR, FR, TestScenario, Test Case or Defect, you can always trace other related items.
