Abstract: Traditional program instrumentation can increase the executing time greatly and bring a great code bloat. In order to eliminate the impact of program instrumentation, a strategy based on control flow path coverage for executable code to eliminate redundant is presented. And a unit test tools for Java executable code is designed to achieve program execution path tracking and coverage analysis. Results show that both the number of instrumentation probes and runtime overhead of instrumentation are reduced effectively.

Key words: dynamic analysis, unit test, program instrumentation, executable code, coverage rate analysis, path tracking

摘要： 为解决传统程序插桩技术存在代码膨胀和运行时间较长的问题，提出对可执行代码进行控制流路径覆盖消除冗余的插桩策略。依据该策略设计一种针对Java可执行代码的单元测试工具，完成程序执行路径跟踪和覆盖率分析。对测试工具进行功能验证和性能分析，结果表明，该策略能够有效减少插桩点数量，降低插桩对被测程序时间特性的影响。
