What's Involved With a Leak Test?

I was talking to my mechanic a few days ago about how we would investigate the power loss my dyno sheets have been showing.I've already checked the compression and the timing (both fine).He said we would start with a leak test and take it from there. I didn't have much time to ask him what was involved but I think it revolves around the I/H/E.
Anybody had this done? Whats involved?

I once had "leak" test when I started my last job!!!
First they give you a cup and then you go into a private Restroom and do your thing. Also...you can't flush the toilet, thats very important!!!

If your talking about a leak down test then you need a special leak down tester. You screw it into where the spark plugs go and use an air compressor to pressurize the cylinder. The tester tells you the % leaking out. You can also listen for air comming out of the exuast, intake, crankcase, or radiator to tell you your problem. What where your compression test numbers?
