Define filter constraints for the given Attribute name. You can define whether matching testcases should be
activated or deactivated and if you want administrative cases to be matched as well. Please note that
administrative cases may not have all of the attributes, so including them may not be effective in most cases.
The Regular Expression field allows you to enter a regular expression that will be matched against the value
of the particular attribute. The expression must be valid, otherwise it cannot be used with the filter.
