嵌入式软件的覆盖测试

覆盖测试是检验嵌入式软件功能结构正确性以及查找问题的重要方法和手段。纯粹的人工测试工作量大、操作不方便、周期长,需要借助一定的工具才能取得较好的效果。使用测试工具LDRA Testbed进行了覆盖率测试,达到了一定的语句、分支以及LCSAJ覆盖率。测试过程说明了该工具能够有效获取被测软件的动态覆盖率信息,评价测试用例的完整性,并有针对性地补充测试用例,进而提高软件测试的覆盖率,帮助决定何时终止软件测试。

Coverage Test of Embedded Software

The coverage test is an important way and measure for detecting the correction of functional structure of embedded software and searching problems.The purely manual test features many disadvantages,e.g.,heavy workload,inconvenience,long cycle,and good effect relied on using specific tools.The test tool LDRA Testbed is applied to do the coverage rate test,and the coverage rate of certain sentences,branches and LCSAJ are reached.The test process shows this tool can effectively acquire the dynamic coverage rate information of the software under test,and evaluate the completeness of test case,and the test case is targeted supplied to improve the coverage rate of software test,and help to decide when to end the software test.
