First-half goals from Kyle Lafferty and Conor Washington and a late strike from Will Grigg helped steer Northern Ireland to a comfortable 3-0 victory over Belarus at Windsor Park, while there were also wins for Uruguay and Nigeria.
The win extended the hosts' unbeaten run to 11 games and provided a further confidence boost for Michael O'Neill's side ahead of their upcoming EURO 2016 campaign.
Lafferty's goal came on the occasion of his 50th cap, while Washington netted his second in as many warm-up games and both strikers are set to be included in O'Neill's finalised squad which is due to be announced on Saturday.
In-form Wigan Athletic star Grigg may also have booked his place in the squad as he opened his international account with a well-taken effort two minutes from time.
Northern Ireland had headed into the game unbeaten at home since September 2013 and that impressive record was rarely threatened once Lafferty fired them in front in the opening minutes.
Belarus, meanwhile, had kept five consecutive clean sheets before arriving in Belfast and were in the midst of an unbeaten run stretching back to last September.
But they struggled to recover from that early setback and gifted the hosts their second goal just before the break courtesy of a glaring error from goalkeeper Andrey Gorbunov.
And although Alyaksandr Khatskevich's men enjoyed plenty of possession throughout the contest, they struggled to break down a resolute Northern Ireland side who sit more than 50 places above them in the FIFA rankings.
Kelechi Iheanacho needed just three minutes to find the winner as Nigeria saw off Mali 1-0 in Rouen.
The Super Eagles had failed to win since beating Niger 4-1 in January and they were kept frustrated for much of the game by Alain Giresse's side in France.
Samson Siasia was shorn of a number of key first-team players for the game, with Victor Moses having asked to be left out due to fitness worries and captain John Obi Mikel joining Ahmed Musa for former defender Joseph Yobo's testimonial match.
That lack of extra quality told in a match short on excitement throughout, with Odion Ighalo missing perhaps the best chance, but substitute Iheanacho struck with 13 minutes to play to secure the win.
