I think if `isATtributeCategorySupported `returns false, we should not return OutputBin[0] as that will cause the test to pass with message "SKip the test as number of supported outputbins is less than 2", which is misleading, in my opinion
It should instead message "Skipping the test as OutputBin category is not supported for this printer"

Also, `getPrintService` returning null also return the above outputbin message..It should rather return "No print service found"
