Partition Level Application Test for Orion (PLATO)

For Orion Exploration Flight Test One (EFT-1), the unit-under-test for flight software verification has been chosen as the entire integrated flight software load. At the time of this reporting, the unit test tool, while powerful, operates on very small units, usually classes. This leaves a sizable gap between unit testing and verification. Orion flight software is divided into ARINC 653 partitions, and partition level testing is in this large gap.
