Testing Lens for sharpness and focus???

[gryffinwings]

Is there a sheet or chart of some sort that I can download to test lens for sharpness and focus, I'm sure all lens are not created equal and would like to test my own lens, considering one of them is used and would like to see the variation between my lens and where they perform best.

Thanks.
