Tries from Willie Walker and Peter Buxton, back in the side following thumb surgery, ensured Dean Ryan's side go into the Premiership campaign with a much-needed victory behind them and equally importantly, a clean bill of health.
Gloucester's 23-19 victory followed an opening pre-season defeat against Cardiff a fortnight ago and Ryan was pleased with the way his side responded in another physical encounter at Ravenhill.
"It was quite lively and pretty competitive but it took us until mid-way through the second half for us to play like I know we can," he said. "In terms of the start of the Premiership, it has certainly clarified a few thoughts about next weekend and that is a good thing.
"A number of performances have given us real indicators ahead of Leeds - I was really pleased with the contributions guys like Luke Narraway, Alasdair Strokosch and Dave Lewis made off the bench and that is good for the whole squad.
"I think it is important we try and get better with each performance, progress what we are trying to do as a squad and build towards the Premiership. These pre-season games have been what we wanted - we have played against good teams, we have had to step up physically and both environments have been tough places to try and get results.
"Our physicality was better and that was important. We will take the good things from the performance and move on ahead of next week."
Gloucester led 10-3 after 20 minutes following Walker's try, conversion and a penalty but the hosts hit back with a try of their own before Walker nudged Gloucester ahead again before the break with another three points.
Buxton marked his return with a second half try and some solid late defence - including a tremendous chase by Lesley Vainikolo, ensured Gloucester closed out the victory.
"I think if we had played like we had done in the second half throughout we may have won more comfortably but it was good for Lesley to get another run-out, we picked up no serious injuries and we can progress from this," Ryan added.
