Heya Barb. Nice to see you here (although, it's unfortunate what has brought you this way).
Many different tests are used to diagnose MS. It's a complicated process.
The initial test is MRI. Be sure they're doing all the way from the top (brain) to the bottom (spine) in your MRI. You can still be diagnosed without lesions (more in a sec), and you can have no lesions on your brain, lesions on your spine, or you can have them in both places.
Evoked potentials is a non invasive way of testing that is also used. Think of the walking down a straight line, 1 foot in front of the other, touching your fingertips to your nose, little mallet hitting your knee to test reflexes...
Blood work, and lots of it usually. This is to rule out 'mimics' that can be found in blood work, including other autoimmune diseases, thyroid, diabetes, vitamin deficiencies.
Lumbar puncture (aka spinal tap). This is to check for "obands". If they're present, that's usually a positive for MS (however, obands can present with other conditions as well).
History, including family history will be looked over.
All these tests will be compiled and most neuros refer to what is called the McDonald criteria. Don't ask any of us to explain it, none of us understand it, that's what the neuro is there for

.
Best of luck with your testing, and don't sweat it. Even I found the LP procedure (it sounds scary) wasn't that bad at all.
