How do you test if camera lenses match?

Hi,      

This might be a question for John B., but here goes.

I searched the archives to try and get a definitive answer as to how
to test if lenses are matched.  I read about taking pictures of grid
patterns and making sure the diagonal measurements of the grid patterns,
were within 1% (?) of each other, but then I'd have to use film and I 
don't want to have to do that.
Would it be sufficient to take them out into the sun and compare their 
infinity focus (see how far from the off white paper each one is when 
it starts to burn the paper).  Then if their infinity focus distance 
is within 1 % (0.1 %?) can I use them to make a stereo camera?
