I haven't tried this yet, but it looks like it might be worth trying. How to test solder joints (http://www.jameco.com/Jameco/workshop/techtip/good-solder-connection.html?CID=NEWS&trk_msg=K6J5071FV80KD2C4EGIFV53O0C&trk_contact=QLK6UPBNOB06JATRJUO3ESK8O0&trk_sid=NMT6P29PIRI0DU3GSECANFO704&espm=1C50A6A1FA2F460189847424FF947803&espc=656F68D5C27769C0ABBB9FB0377288C0&utm_source=Listrak&utm_medium=Email&utm_term=Solder+Good&utm_campaign=NEWS&utm_content=NEWS).
results may vary on double sided or multi-layer pcbs
Not to brag... but I'm *very* careful and particular when it comes to making solder joints.
I go slow and careful.
Cannot think of a single instance when I had a bad solder joint of my own doing.
(maybe when I was much younger and first starting this thing called electronics)
If I make one and it doesn't look or feel right, I re-do it right away.
Been repairing/modifying/fixing/building electronics stuff for many years now.

This, definitely. Not sure the tin foil thing will test anything but a joint with too much solder. A good one has a nice, slightly concave fillet and the lead is clipped slightly above. Which makes this test a little misguided imho.
