Genetic Algorithm (GA) has been successfully used by researchers in software testing to automatically generate test data. In this paper, a GA is applied using branch coverage criterion to generate the least possible set of test data to test JSC applications. Results show that applying GA achieves better performance in terms of average number of test data?generations, execution time, and percentage of branch coverage.展开更多

Java card programs (applets) run in Java Card Runtime Environment (JCRE) including the Java Card Virtual Machine (JCVM), the framework, the associated native methods and the API (Ap plication Programming Interface). JCVM is implemented as two separate pieces: off-card VM (Virtual Machine) and on-card VM. The stack model and heap memory structure used by on-card VM and exception handling are introduced. Because there airs limited resources within smart card environment, and garbage collection is not supported in JCVM, the preferred way to exception handling does not directly involve the use of throw, although the throw keyword is supported. Security is the most important feature of smart card. The Java card applet security feature is also discussed.展开更多
