Eli,
Start with the standard tests such as the brass rod. We want to know if the edge chips or rolls over. The blade should bend to about 30 degrees without breaking. When it does break we want to see a fine grain structure. If the edge geometry is too poor to give fair results you may have to regrind the blade a little yourself.
That is the important stuff: this is all about getting the HT correct. Sharpness and cutting ability are, of course, affected by the HT but the edge geometry is just as important for that. This isn't about edge geometry, it's about the quality of the HT - stay focused on that. You can test sharpness and geometry if you want to go through that, it would be helpful, but the HT is what this is about and we don't want to lose sight of that ....
