The Spacecraft Automatic Testing Engine Based on Workflow

Spacecraft automatic testing plays an essential role in spacecraft testing field for over a decade. However, less attention has been paid on the spacecraft automatic testing technology based on workflow methodology. In this paper we introduce workflow technology into testing for improving the automation of spacecraft testing. Firstly we present a spacecraft testing process definition language STPDL based on XPDL. Then the architecture of spacecraft testing workflow engine is proposed for parsing STPDL. In addition, we give core scheduling algorithm and the implementation detail of the spacecraft testing workflow engine. At the end of the paper we give the future of our workflow engine.
