摘要

实时嵌入式系统(RTES)在控制我们日常使用的IT方面发挥着越来越重要的作用。RTES的行为不仅取决于它与周围环境的相互作用,还取决于它所引起的时序要求。因此,确保RTES行为正确是非常重要的,特别是在将时间作为测试过程复杂性的新维度添加之后。在之前的研究中,我们引入了一种“基于优先级”的方法,该方法测试了正式建模为UPPAAL时间自动机(UTA)的RTES的逻辑和定时行为。“基于优先级”的方法基于根据三组优先级,即边界、边界外和边界内,实现时间约束覆盖,从而产生计时测试跟踪集。在本文中,我们介绍了一个新的测试工具“GeTeX”,它部署了“基于优先级”的测试方法。GeTeX是一个完整的测试工具,它从UTA模型生成定时测试用例,并在被测系统(System Under Test, SUT)上执行它们以识别故障。在其当前版本中,GeTeX支持控制局域网(CAN)应用程序。

GeTeX: A Tool for Testing Real-Time Embedded Systems Using CAN Applications
Real-Time Embedded Systems (RTES) have an increasing role in controlling the IT that we use on a day-to-day basis. The behaviour of an RTES is not based solely on the interactions it might have with its surrounding environment, but also on the timing requirements it induces. As a result, ensuring that an RTES behaves correctly is non-trivial, especially after adding time as a new dimension to the complexity of the testing process. In previous research, we introduced a 'priority-based' approach which tested the logical and timing behaviour of an RTES modeled formally as UPPAAL Timed Automata (UTA). The 'priority-based' approach was based on producing sets of timed test traces by achieving timing constraints coverage according to three sets of priorities, namely boundary, out-boundary and in-boundary. In this paper, we introduce a new testing tool 'GeTeX' that deploys the "priority-based" testing approach. GeTeX is a complete testing tool which generates timed test-cases from UTA models and executes them on the System Under Test (SUT) to identify faults. In its current version, GeTeX supports Control Area Network (CAN) applications.
