摘　　要：DO-178B要求验证机载软件在目标机环境中正确运行,所以必须在受控的真实测试环境中运行插桩代码,提出基于LDRA Testbed的主机/目标机测试方法。介绍该方法的提出背景、原理、通信方式、面临的问题和测试环境的构建,构建方法减小因插桩引起的源代码膨胀和干扰时序的影响,并在测试环境中创建延时取回的算法以获取累积的历史记录文件,最终得到有效的动态覆盖率测试报告。从软件的健壮性和可靠性层面上有效提高机载软件的质量。DO-178 B requires to verify the correct execution of airborne software in the target environment, so the instrumented code must be run in the controlled real test environment. A host/target testing method based on LDRA Testbed is proposed. The background, principle, communication mode, problems and construction of test environment were Introduced. The construction method reduces the impact of source code expansion and interference timing caused by instrumentation, and creates a delay retrieval algorithm in the test environment to obtain the accumulated execution history files. An effective dynamic coverage test report was obtained. Host/target testing method can improve the quality of airborne software from the robustness and reliability effectively.
