Hi,
Yes it is a bug. In system tester it is not possible to compare the tests
which are not having different opt values. When I want to compare different
system tests at once, I add very small change in one of the opt values or I
do it manually running tests one by one and collecting results on excel( in
this case test name is not included in the report !).
regards,
taylan sekerci
