[软件设计/软件工程] Softare-testing-method

本文提出的基于统计方法的软件测试方法,是能生成具备一定充分性的测试 用例的方法,是更适合软件工程实践的测试方法。该方法根据用户对软件的使用 方式展开,对使用频繁的操作会进行更多的测试,因此可以有效地发现那些对软 件可靠性影响较大的错误。统计测试首先构造出软件的马尔科夫链使用模型,根 据该使用模型生成测试用例,实施测试后按照统计学模型对测试结果进行分析, 从而评价软件可靠性和质量。鉴于关软件可靠性测试用例充分性准则的研究较少, 本文提出了如何判断测试用例充分性的新方法。 在研究基于统计方法的软件测试基础上,本文设计实现了一个基于马尔科夫 链模型的统计测试工具“MBCGA’’,它实现了构建软件马尔科夫链使用模型,参 数分析,生成测试用例,分析测试用例等功能,帮助测试人员生成具备充分性的 测试用例,为测试人员提供了一个实用、易操作的基于统计方法进行软件测试的 辅助工具。 利用统计测试工具“MBCGA”对车辆动力舱计算机辅助布局设计系统进行测 试。更好地验证了基于统计方法的软件测试是一种有效加高效的测试方法,是成 功的基于模型的软件测试,可以很好的用于软件可靠性评估与预测。
This paper proposes a SOfhare testing method based on statistical.It is a method that Can generate sufficient testcases,and it is also a method more fit for software practice.This method bases on the users’using mode,and pays more attention to frequent operation,SO it’S effective to find the mistakes that own much more influence. Statistical testing constructs software’S Markov chain usage model firstly,generates testcases according to usage model,analyses the test result according to statistical model after test the software,then uate the software’S reliability and quality.Rule of judging adequate testcase about software’S reliability is deficient,SO this paper proposes a new method that Can generate sufficient testcases. With the basis of statistical testing theory,this dissertation designs and develops a statistical testing tool“MBCGA”based on Markov chain,it supports Markov chain usage model building,parameters analysis,test cases generation and analysis and SO on.

大学的每个专业都要制订教学计划。假设任何专业都有固定的学习年限,每学年含两学期,每学期的时间长度和学分上限均相等。每个专业开设的课程都是确定的,而且课程在开设时间的安排必须满足先修关系。每门课程有哪些先修课程是确定的,可以有任意多门,也可以没有。每门课恰好占一个学期。试在这样的前提下设计一个教学计划编制程序。
University of each professional should develop teaching programs. Assuming that any profession has fixed the length of each school year with two semesters, the length of time each semester are equal to the credit limit. Each professional courses are determined, and the courses offered at the opening time arrangements must meet pre relations. Each course what Advanced Placement is determined, there can be any number of doors, you do not. Accounted for just one semester each course. In this context try to design a teaching program procedures. (2013-07-14, Visual C++, 218KB, 下载1次)
