If you have a multimeter you can test it yourself (or you can get one for $40 at Home Depot). Test the battery (car off) should be above 12 volts. Then test with car on (now you are testing the alternator) should be 13.5 or more. This is not as good as an actual load tester, but it is a good way to start if you have the tool.
