Compression test is pretty simple. The basics are: remove sparkplugs, insert tester into one cylinder, fully open throttle, and crank engine through at least 4 compression strokes, jot down the reading. Repeat 5 more times. You may also want to disable your fuel system so that you aren't filling other cylinders with fuel. Also due this test on a warm engine. I also like to remove the coil wire.

Hope this helps, Jeff
