Connor McLennan, Miko Virtanen, Bruce Anderson and Ethan Ross who were all in the travelling party which went to Finland featured in the starting eleven.
The Dons dominated the early possession, but shots from Ethan Ross and McLennan didn't seriously test keeper Dey.
Chasing a wayward pass, Calvin Ramsay collided with the perimeter fencing and required treatment from physio George Good before returning to play. The crowd were on their feet as Cammy Keith forced a great save from Sam Jackson, but the flag was up for offside.
Keith's Marc Young was booked on 19 minutes after a late challenge on Ethan Ross which left the teenager writhing in agony. Fortunately, Ethan was able to continue as it was a poor tackle from the full back.
A neat move instigated by Seb Ross ended with the skipper dragging his shot wide after he had been found by Miko Virtanen. Bruce Anderson tried his luck from distance but Dey was able to watch the ball fly over. Then Virtanen fired in a shot which on this occasion the keeper had to save diving to his left.
On 33 minutes, Connor McLennan came off to be replaced by Chris Antoniazzi. Jamie Lennox then came close for Keith before Bruce Anderson broke the deadlock on 38 minutes. Ethan Ross battled hard to win the ball on the left before unselfishly squaring for Anderson to slot home from 6 yards.
Aberdeen were beginning to dominate proceedings and Ramsay was just a foot too high with a fierce left-footed shot as they sought a second goal.
A solid first half from the Dons whose goal was never really threatened, but they will be looking to show more of a cutting edge in the second period.
Half time - Keith 0 Aberdeen XI 1
Michael Ruth almost made it two on 47 minutes, but a fine save at his near post from sub keeper Simpson denied the former Queens Park man. Simpson was in action a few seconds later, tipping Anderson's effort over.
Ruth was inches away from converting Antoniazzi's cut back after a wonderful reverse pass from Ethan Ross as the Dons began to tighten the screw. A fine run from Anderson saw the striker create space for a shot which forced an excellent block from McAllister to divert it to safety.
Keith had a chance on 58 minutes when substitute Barron headed over after he had been picked out by an excellent cross from Macaskill. Simpson then produced another two fine saves to deny Seb Ross and Antoniazzi.
Keith won a penalty on 62 minutes when Ramsay was harshly ruled to have handled. Ace marksman Cammy Keith stepped forward to slam the ball past Jackson to tie things up at one apiece. A memorable moment for the man of the moment.
Parity didn't last long though as a neat finish from Bruce Anderson put the Dons back into the lead. And he should have been celebrating a hat-trick shortly after when Ruth played him in, but Simpson pulled out yet another fine stop to deny the striker.
Ruth was next to be denied by Simpson after Hanratty and Chesser had replaced Ramsay and Ethan Ross.
Kieran Shanks was given a late run out and he could have scored with his first touch, but shot wide. At the other end, a headed clearance from Jackson fell for Barron, his shot wild as it sailed high and wide of an untenanted goal.
Luke Turner was Aberdeen's final change as he took over from Robertson. McAllister threw his body in the way of a net-bound Anderson shot as the home side continued to defend doggedly, determined not to let Aberdeen kill the game off. An entertaining Testimonial match, Cammy Keith fittingly getting the home side's goal, but Bruce Anderson's double strike gave Aberdeen the win. It could have been more for The Dons, but a combination of good goalkeeping and a defence well marshalled by Ryan Robertson (brother of ex-Don, Clark) kept the scoreline at 1-2.
Next up, it's Huntly at Christie Park on Tuesday evening.
