Jeep Repair: 06 Jeep GC not starting, battery tested good., reputable repair shop, autozone

Question
I have been having issues with starting my vehicle for the last 2 months. At first it happened once or twice in a month and now this week it has been everyday and it is getting worse. When i go to start the vehicle it clicks once but does not start. I had a friend test the battery and it tested bad, but it was an older battery tester. So to get a 2nd opinion i took it to autozone where a gentleman there tested it along with the starting system. He said that by his machine that the battery was fine and the starting system was having no issues either. Whenever the vehicle does not start i have to get it jumped off and it usually takes it about 15 minutes to start when getting the boost. I called the dealership but they dont have any openings for another 2 weeks. I need help!!!!!

Answer
It sounds like the starter is going bad from your description. There is no fix other than replacing it. And unless your Jeep is under warranty, there is no need to bring it there to have the work done. Any reputable repair shop can replace the starter.
