I would like to see how many requirements are not covered by my current test plan : ie. I want to select a test plan, display the "requirements based tests" and see the requirements not covered by the selected plan.
So I wondered how I can get some "uncovered requirements" in the Reports and Metrics panel.
According to the user manuaI, I should be able to get the following metrics :
• Total number of requirements
• Requirements within TestLink
• Requirements covered by Test Cases
• Requirements not covered by Test Cases
• Requirements not covered or not tested
I can also read "The report is generated against one Requirement Specification document chosen from combo box menu."
I have to say I don't know where I can choose the requirement specification document

Thx for your help
Best regards
