Abstract: In order to accelerate the data manager system testing rate of progress, the general test platform for data manager system of spacecraft was designed and structured. The standardization of the testing method and system framework was realized by the platform to study the testing objects. General availability of software and hardware of the system was fully considered, and a development environment that based on the LUA with good portability was introduced, so the reconfigurable test platform which fits in many types of the dms can be build quickly. A number of model tests show that general test platform for data manager system of spacecraft can significantly reduce the test cycle and the development costs, the operation is stable and reliable, and has achieved the desired purpose.
