基于任务场景的测试需求建模方法

摘要

The existing methods for modeling test requirements can not be used to describe requirements for function,perfor-mance and reliability testing simultaneously.To solve this problem,a test requirement modeling method based on task scenario named as TreBts was proposed.Considering a complex test task containing three types of testing,a TreBts conceptual model was derived and three types of views were designed.Based on these,a modeling procedure was provided;besides a test process based on TreBts was given to guide testers to conduct testing.Finally,a case study was carried out and the results show that all three types of test requirements can be accurately described in the TreBts model,and the test suites generated automatically can fulfill the three types of requirements.%针对现有的测试需求建模方法不能同时描述功能、性能和可靠性测试需求的问题，提出一种基于任务场景的测试需求（TreBts）建模方法。从测试系统执行复杂测试任务的角度出发，建立 TreBts 的概念模型并设计3类视图；在此基础上，给出3类视图的建立指南及基于 TreBts 模型的测试流程，指导测试人员开展测试。实验结果表明，TreBts 可准确描述3种类型的测试，自动生成的测试套可完全满足每类测试需求。
