Hi!
I would like to know if I can use already used columns for validation of methods? I have columns that have already been used for execution of many different methods and I dont know, if they are appropriate for validation of new method. I would like to know if there are any guidelines for useing new, unused or already used columns for validation of methods.
I do have some new columns and I would like to know, if I have to check, if new columns are ok?
