How does one go about checking if the ballast in these fixtures are bad or how to check the (bulb?) holders to see if they are bad? I have a 2 light fixture that after replacing both lights one is not working.
Thank You, Stan

Check for voltage at the wire nuts prior to the ballast. If voltage there, just replace with a LED fixture. They are cheep enough to not really worry about more proper diagnostics.

Cheap and cheerful diagnostics would be replacing the non-working tubes with tubes that are working. If the light then works, it's not the ballast. If it doesn't, it's the ballast.
And if the ballast is bad, I would replace the tubes with line-voltage LED bulbs, which requires removing the ballast and doing some very minor rewiring. Or toss the whole thing and buy an LED fixture. Either one. But don't get LED bulb replacements that require the ballast to be there, as a bad ballast it what started the whole thing.
