The Hatters made it four consecutive victories in pre-season as they ran out 2-0 winners at Vanarama National League side Boreham Wood.
Pelly-Ruddock Mpanzu opened the scoring early on with a low shot from 12 yards, before Olly Lee headed home Jack Stacey's cross just after the restart.
Town started off well as in the eighth minute Mpanzu made a bursting run from inside his own half, stepping over the ball to take him past a Boreham Wood player before moving it onto Lawson D'Ath.
He played it back to Mpanzu who tried to tee up Vassell on the edge of the Wood's 18-yard box, but the move didn't come off as the hosts managed to get players back to bring the attack to a halt.
The Wood didn't learn from that lesson though as Alan McCormack was allowed space inside his own half which he utilised as he brought the ball forward. He sent Pelly-Ruddock Mpanzu through with an excellent pass and the 23-year-old had the simple job of slotting past keeper Grant Smith, which he did so confidently to give the visitors a 1-0 lead.
Luke Garrard's side pushed for an equaliser and came close on the 15th minute when a goal line clearance from Dan Potts after a scramble in the Hatters' box was all that kept the hosts out.
The Wood then caught Town short at the back ten minutes later as Johnny Mullins' headed clearance only went as far as Angelo Balanta, but his strike from 20 yards deflected off Scott Cuthbert and was cleared away.
Former Town striker Paul Benson should have brought the score level a minute before the half hour mark, as he met Kane Smith's cross to the back stick, but he could only guide it wide.
The Hatters made two changes at the break, bringing on Olly Lee and Akin Famewo for Pelly-Ruddock Mpanzu and Johnny Mullins, and the former of those changes proved fruitful almost immediately.
Six minutes after the restart Lee slotted Shinnie through for the Scotsman to strike the ball from 20 yards, which forced a good save from Grant Smith, but he could only palm into the path of Jack Stacey who crossed for Lee from the right and the ex-West Ham United and Birmingham City midfielder headed in from six yards.
Bruno Andrade tested Marek Stech with some free-kicks from range as Wood grew into the game with ten minutes to go, but they weren't enough to trouble the stopper.
Luke Gambin had the chance to wrap up the result in the dying minutes as Kavan Cotter played an inch perfect pass out to Musonda, who fed it to Cook, he then tapped it onto the Maltese international who lined up the shot, but his curling effort from 18 yards flew well over the bar.
Town's next pre-season game is at home to Leicester City this Wednesday.
