Well easiest way requires voltmeter across battery which should show about 12.5 volts with engine off, and about 13.5-14 with engine running and alternator working properly.
Alternators are sometimes replaced for noisey bearings even tho' they are OK electrically.
What reason did mechanic give when he suggested replacement?
98 Mystique LS v6 atx 110,000km
97 Contour LX v6 atx 125,000km
stock CD on LS, cass on LX
spoiler, tinted windows on LS only
4 wheel discs on LX only
All other available options on both
