The first will be at Cardiff's Millennium Stadium on August 8 before a trip to Dublin and the Aviva Stadium on August 29.
And Kearney, who played in ten GUINNESS PRO12 matches for Leinster last season, believes the games will give the players the perfect chance to fine tune their fitness.
"They won't be friendly at all, they'll be full-on Test matches," he told WalesOnline.
"But it's a double-edged sword. These games do get you ready but at the same time, you don't want injuries.
"It's important to get match fitness up, put your hand up for selection and start to try and find your form.
"As soon as you come into round one of the tournament you can't be chasing things - that's why the warm-ups are so important.
"There will be players who will be there or thereabouts for the final squad and there'll be some looking for form."
