AI Technical Summary
Existing Java card coverage statistics methods suffer from insufficient space utilization, inaccurate coverage statistics, and low development efficiency. Especially with the continuous increase in Java card functionality, traditional instrumentation methods consume additional code and storage space, and the difference between the simulator and the actual card operating environment leads to inaccurate statistics.
An embedded Java card coverage statistics method without instrumentation is adopted. By configuring the Java card conversion tool to generate line number matching files and structure information files, and combining instruction tracing macro units to collect runtime data in real time, a coverage analysis report is generated. This avoids additional modifications to bytecode files and uses hardware emulators, software emulators or physical Java cards for data collection and analysis.
It enables a more accurate reflection of Java card operation in the actual operating environment, avoids space occupation issues, improves resource utilization efficiency and coverage statistics accuracy, and provides detailed test data to improve development efficiency.
