Co-testability Transformation

Authors: Philip McMinn


Abstract
This paper introduces the notion of ‘co-testability transformation’. As opposed to traditional testability transformations, which replace the original program in testing, co-testability transformations are designed to be used in conjunction with the original program (and any additional co-transformations as well). Until now, testability transformations have only been used to improve test data generation. However, co-testability transformations can function as partial oracles. This paper demonstrates practical usage of a co-testability transformation for automatically detecting floating-point errors in program code.

Fuzzy Logic Based Objective Function Construction for Evolutionary Test Generation

Authors: Andrea G. B. Tettamanzi


Abstract
The test case generation problem can be stated as an optimization problem whereby the closeness of test cases to violating the postcondition of a formal specification is maximized, subject to satisfying its precondition. This is usually implemented by constructing an objective function which provides a real-valued estimate of how distant all of the constraints are from being violated, and then trying to minimize it. A problem with this approach is that such objective functions may contain plateaux, which make their minimization hard. We propose a similar approach, grounded on fuzzy logic, which uses, instead of a "distance from violation" objective function, a fuzzy degree of proximity to postcondition violation and produces plateaux-free objective functions by construction. The approach is illustrated with the help of a case study on the functional (black-box) testing of computer programs.

Ideas on Signal Generation for Evolutionary Testing of Continuous Systems

Authors: Andreas Windisch


Abstract
Test case generation constitutes a critical activity in software testing that is cost-intensive, time-consuming and error-prone when done manually. Hence, an automation of this process is required. One automation approach is search-based testing for which the task of generating test data is transformed into an optimization problem which is solved using metaheuristic search techniques. However, only little work has so far been done to apply search-based testing techniques to systems that depend on continuous input signals rather than single discrete input values. This paper proposes three novel approaches to generating input signals from within search-based testing techniques for continuous systems.

SAT-based Automatic Test Pattern Generation

Authors: Rolf Drechsler, Stephan Eggersglüß, Görschwin Fey, and Daniel Tille


Abstract
Due to the rapidly growing size of integrated circuits, there is a need for new algorithms for Automatic Test Pattern Generation (ATPG). While classical algorithms reach their limit, there have been recent advances in algorithms to solve Boolean Satisfiability (SAT). Because Boolean SAT solvers are working on Conjunctive Normal Forms (CNF), the problem has to be transformed. During transformation, relevant information about the problem might get lost and therefore is not available in the solving process. In the following we briefly motivate the problem and provide the latest developments in the field. The technique was implemented and experimental results are presented. The approach was combined with the ATPG framework of NXP Semiconductors. Significant improvements in overall performance and robustness are demonstrated.

SoftwareTesting with Active Learning in a Graph

Authors: Nicolas Baskiotis, Michèle Sebag, and Marie-Claude Gaudel


Abstract
Motivated by Structural Statistical Software Testing (SSST), this paper is interested in sampling the feasible execution paths in the control flow graph of the program being tested. For some complex programs, the fraction of feasible paths becomes tiny, ranging in $[10^{-10}, 10^{-5}]$. When relying on the uniform sampling of the program paths, SSST is thus hindered by the non-Markovian nature of the ``feasible path'' concept, due to the long-range dependencies between the program nodes. A divide and generate approach relying on an extended Parikh Map representation is proposed to address this limitation; experimental validation on real-world and artificial problems demonstrates gains of orders of magnitude compared to the state of the art.

Using evolutionary algorithms to select parameters from equivalence classes

Authors: Felix Lindlar and Abel Marrero Pérez


Abstract
This paper presents some ideas about an approach which aims at extending existing methodologies for functional testing. Experience in automotive applications has shown that when selecting parameters for functional testing, many times a tester has equivalence classes in mind. Instead of losing valuable information in the process, support should be given to make them manageable. The proposed approach suggests evolutionary testing strategies to search for critical representatives within equivalence classes.
