Glasgow head coach Dave Rennie says Saturday's showdown with Leinster is the perfect yardstick to measure his team's play-off chances against.
Warriors have already booked their slot in the Guinness PRO14's end-of-season shoot-out but - with two games to play and only three points of a cushion over Munster - the Conference A leaders still have to seal a home semi-final.
But that is something reigning league and European champions Leinster do not have to worry about having opened up a 20-point lead at the top of Conference B.
However, if the play-offs go to form, this weekend's combatants at the RDS Arena will be squaring off again in the Celtic Park final and Rennie is eager to see just how closely his side are matched to the Irish leaders.
He said: "We're looking forward to testing ourselves against the best team in Europe.
"It's an exciting challenge and exactly the kind of game we need as we gear towards knock-out footy.
"We've prepared well and I expect to see the same levels of desperation and brutality that we saw against Ulster on Friday night."
Rennie has made two changes to the side which beat Ulster 30-7 at Scotstoun last Friday to earn maximum points.
Up front Scott Cummings comes into the second-row with Rob Harley shifting to six and Jamie Bhatti starting at loose-head.
The Kiwi has named an unchanged backline, with Adam Hastings and Tommy Seymour retaining their slots after both scored against Ulster.
Huw Jones has been named amongst the replacements and will play his first game since sustaining a knee injury whilst playing for Scotland against Ireland in this year's Guinness Six Nations in February.
