i just found this focus test chart in a pdf file, perhaps someone can use it?

May be.
Just make proper topic title next time.
Very useful for the specific kind of test described there (at 45 degree angle). You can judge the bokeh behavior too to some degree.
A good general test chart is here: http://www.graphics.cornell.edu/~westin/misc/res-chart.html
Print it LARGE or with a very fine printer (it scales perfectly, being vector graphics).
