基于耦合测试信息元数据模型的构件集成测试

文中提出一个方法,由构件开发方提供有关构件内接口变量定义和使用的信息,以提高构件的可测试性和可理解性.形式化地定义了构件耦合测试准则,定义-使用属性和观察点值.在此基础上,引入包含上述两项属性的定义-使用表(DU表),给出基于该表的构件框架.最后将上述方法应用于自主开发的构件中,并生成了相应的测试用例.将文中提出的方法与Orso方法和Kan方法进行了相关的比较,结果表明文中方法无论在测试用例生成,还是在变异发现上都更有效.

Component Integration Test Based on a Metadata Model of Coupling Testing Information

This paper introduces a method to increase testability and understandability of component based on definitions and uses information of interface variables about component provided by component developers.Then formal definitions of component coupling testing criterion, definition-use attributes(DU-As) and observation-point values(OP-Vs) are given.Based on these,a definition-use table(DU-Table) is introduced,which includes DU-As and OP-Vs item.Then a framework of testable component based on above DU-Table is given.Above methods are applied to the component developed by themselves before,and related test cases are generated.Moreover above method is compared with Orso method and Kan method using same example,presenting the comparison results.The results illustrate the validity of above method,effectively generating test cases and finding more mutants.
