Test research of coal quality management system based on model driven architecture

In view of problems of changing business logic, high software development cost and difficult maintenance, a model test method based on model driven architecture was proposed. Through establishing test model，executing the test case after joining action specification language and feeding back the test result, the defects of the model are found and the model is reconstructed in time to improve quality of the system. Modeling and test were conducted combined with drawing of working face and heading face in coal quality management system, and it verifies feasibility of the method.
