1. A method of semiconductor testing comprising:
- while a test program is being applied to a semiconductor device, deciding that said device is testing too slowly and that based on a yield criterion said device is to be prevented from completing said test program; and
preventing said device from completing said test program;
wherein after said device has been prevented from completing said test program and if there is at least one remaining untested semiconductor device, said test program is applied to at least one of said remaining untested semiconductor devices.

18. A non-transitory computer program product comprising a non-transitory computer useable medium having computer readable program code embodied therein for semiconductor testing, the computer program product comprising:
-
computer readable program code for causing the computer, while a test program is being applied to a semiconductor device, to decide that said device is testing too slowly and that based on a yield criterion said device is to be prevented from completing said test program; and computer readable program code for causing the computer to prevent said device from completing said test program; wherein after said device has been prevented from completing said test program and if there is at least one remaining untested semiconductor device, said test program is applied to at least one of said remaining untested semiconductor devices.
