Hi I have workflow script to automatically add req coverage to test, below are the steps which I did for that
1. Enabled a used defined button in test plan
2. Req ID is part of a uder defined colum in test
3.Subject value is hardcorded
4.Script will loop through all test cases in suject and will call Test.addCoverage ReqID

But I do not want to hardcode the subject, when i click on userdefied button currently selected suject should be used, I am not sure how to get this selcted node value in workflwo script

Please help.
