>>i have diff. J2EE layers in project like ejb , Bussiness object and database layers . now in Juit test i have to write test cases for all the classes present but i'm facing the problem in taking out the data from database ,as in test cases i do not want to start server , and the properties file is loaded only when server starts . >> is there any method available that without starting server i can test my classes for example create method .. it passes through EJB ..Bussineess Logic .. and persist data in Database . Any solution or suggestion is most welcome !!!
