Abstract The verification of model transformations is important for realizing robust model-driven engineering technologies and quality-assured automation. Many approaches for checking properties of model transformations have been proposed. Most of them have focused on the effective and efficient detection of property violations by contract checking. However, there remains the fault localization step between identifying a failing contract for a transformation based on verification feedback and precisely identifying the faulty rules. While there exist fault localization approaches in the model transformation verification literature, these require the creation and maintenance of test cases , which imposes an additional burden on the developer. In this paper, we combine transformation verification based on symbolic execution with spectrum-based fault localization techniques for identifying the faulty rules in DSLTrans model transformations. This fault localization approach operates on the path condition output of symbolic transformation checkers instead of requiring a set of test input models. In particular, we introduce a workflow for running the symbolic execution of a model transformation, evaluating the defined contracts for satisfaction, and computing different measures for tracking the faulty rules. We evaluate the effectiveness of spectrum-based analysis techniques for tracking faulty rules and compare our approach to previous works. We evaluate our technique by introducing known mutations into five model transformations. Our results show that the best spectrum-based analysis techniques allow for effective fault localization, showing an average EXAM score below 0.30 (less than 30% of the transformation needs to be inspected). These techniques are also able to locate the faulty rule in the top-three ranked rules in 70% of all cases. The impact of the model transformation, the type of mutation and the type of contract on the results is discussed. Finally, we also investigate the cases where the technique does not work properly, including discussion of a potential pre-check to estimate the prospects of the technique for a certain transformation.
模型转换的验证是实现鲁棒模型驱动工程技术和质量保证自动化的重要手段。人们提出了许多检查模型转换属性的方法。其中大多数侧重于通过合同检查有效和高效地发现财产侵权行为。然而,在基于验证反馈识别转换的失败契约和精确识别错误规则之间仍然存在错误定位步骤。虽然在模型转换验证文献中存在故障定位方法,但这些方法需要创建和维护测试用例,这给开发人员带来了额外的负担。本文将基于符号执行的转换验证与基于谱的故障定位技术相结合,用于识别DSLTrans模型转换中的故障规则。这种故障定位方法使用符号变换检查器的路径条件输出,而不需要一组测试输入模型。特别地,我们引入了一个工作流,用于运行模型转换的符号执行,评估定义的契约的满意度,以及计算跟踪错误规则的不同度量。我们评估了基于频谱的分析技术用于跟踪错误规则的有效性,并将我们的方法与以前的工作进行了比较。我们通过在五个模型转换中引入已知的突变来评估我们的技术。我们的结果表明,最好的基于频谱的分析技术允许有效的故障定位,显示平均考试分数低于0.30(少于30%的转换需要检查)。这些技术还能够在70%的情况下将错误规则定位在排名前三的规则中。讨论了模型变换、突变类型和契约类型对结果的影响。最后,我们还研究了该技术不能正常工作的情况,包括讨论潜在的预检查,以估计该技术对某个转换的前景。

Counterexample classification 反例的分类

In model checking, when a model fails to satisfy the desired specification, a typical model checker provides a counterexample that illustrates how the violation occurs. In general, there exist many diverse counterexamples that exhibit distinct violating behaviors, which the user may wish to examine before deciding how to repair the model. Unfortunately, (1) the number of counterexamples may be too large to enumerate one by one, and (2) many of these counterexamples are redundant, in that they describe the same type of violating behavior. In this paper, we propose a technique called counterexample classification. The goal of classification is to cover the space of all counterexamples into a finite set of counterexample classes, each of which describes a distinct type of violating behavior for the given specification. These classes are then presented as a summary of possible violating behaviors in the system, freeing the user from manually having to inspect or analyze numerous counterexamples to extract the same information. We have implemented a prototype of our technique on top of an existing formal modeling and verification tool, the Alloy Analyzer, and evaluated the effectiveness of the technique on case studies involving the well-known Needham–Schroeder and TCP protocols with promising results.

在模型检查中,当一个模型不能满足期望的规范时,一个典型的模型检查器会提供一个反例来说明违反是如何发生的。一般来说,存在许多不同的反例,它们表现出不同的违反行为,用户可能希望在决定如何修复模型之前检查它们。不幸的是,(1)反例的数量可能太大,无法一一列举,(2)许多反例是多余的,因为它们描述了相同类型的违规行为。在本文中,我们提出了一种称为反例分类的技术。分类的目标是将所有反例的空间覆盖到有限的反例类集合中,每个反例类描述给定规范的不同类型的违反行为。然后将这些类作为系统中可能违反行为的摘要呈现,从而将用户从手动检查或分析大量反例以提取相同信息的过程中解放出来。我们已经在现有的正式建模和验证工具Alloy Analyzer上实现了我们技术的原型,并在涉及著名的Needham-Schroeder和TCP协议的案例研究中评估了该技术的有效性,并取得了令人满意的结果。
