A test ROM is a program designed specifically to test whether the platform that the program is running on is working correctly. A test ROM can be used to test the accuracy of an emulator, as well as compare the behavior of different hardware revisions.

Blargg's tests

Blargg's tests are available at: http://blargg.parodius.com/gb-tests/

All tests were executed in each emulator's DMG mode, except the CGB sound test, which was executed in both DMG and CGB modes.
