Try jump starting again. If it starts, then I would suspect a bad battery. AZ and other parts store testers aren't always accurate. Even the one we have at work can err on the side of pass on a bad battery sometimes, not often, but sometimes.
^^ Although it's never happened to me, I've seen this same thing reported a number of times on various auto forums.
And just an aside that I can never understand why so many people just hang on parts instead of trying to do a bit of research and diagnose problems. I guess maybe it seems like the easiest thing to do, but so often it works out just the opposite.
