The Research And Realization On Java Card Code Coverage Measurement Technology

Java smart card is drawing more and more the attention of the industry and can be widely applied with its unique capacity,high stability, good security and a series of characteristics such as the development of convenient.Development and testing of the Java Card program plays a vital role for the success or failure of the Java Card products. In the Java Card program testing, code coverage is often used as an important indicator to measure the program is good or bad. Measure of the degree of code coverage are many kinds of statement coverage, branch coverage, path coverage, select a different measure of code coverage testing on Java cards have different results.This thesis is the research of the Java Card code coverage measurement techniques and tools to achieve. a code for the Java Card Virtual Machine (JCVM) coverage testing tool JCCover was Participated in the development based on code coverage metrics. The tool as the first tool for Java card test code coverage,which is in practical application of great significance.The main contents of this article are the following aspects:1, code coverage in software testing theory of measurement techniques in-depth research, analysis and compare the advantages and disadvantages of various measurement techniques.2, the working principle of the Java Card, and works based on the Java Card Virtual Machine (JCVM), design for JCVM the code coverage statistics.3, the JCCover as an Eclipse plug-in the form of the contents of the study, and the tools were tested.
