Dead Pixel Test Documentation
This tool allows you to check your camera for dead pixels. It also reports hot pixels which depending on the length of the exposure and the threshold used in the test can be attributed to normal noise.

How it works
Make a lens cap shot. Close the lens with your lens cap, also make sure to close the viewfinder so no light can get into the camera. Now make exposures with different shutter speeds ranging from 1/30, 1 second, 2 second and more.
Best results will be with TIFF files or other non-compressed or loss less compressed files as JPEG artifacts will introduce more dead/hot pixels than you really have.
