Efficient JavaScript Mutation Testing

TL;DR: The results indicate that JavaScript programmers and testers need tools that can help them reason about the Document Object Model, and developers can use the error patterns found to design more powerful static analysis tools for JavaScript.

Abstract: Context: Mutation operators play a crucial role during the mutation testing process due to their capability to model common faults to be injected into an application under test. In the context of the Android OS, the academic literature shows that different studies propose mutation operators, especially focusing on the GUI and configuration. On the other hand, few devise mutation operators for specific Android device resource components such as connectivity, location, and sensors. Objective: Therefore, this paper aims to investigate the design and proposition of mutation operators for Bluetooth, Location, and the third-party library AltBeacon. The rationale is that this paper is carried out in an academia-industry partnership, in which the company develops applications that rely on these Android components. Method: The design process used a systematic approach named HAZOP to minimize any possible bias. Results: This systematic process helped in deriving a set of 16 mutation operators. Next, the paper provides an empirical cost evaluation that assesses the number of generated mutants for two applications and the number of generated mutants per operator, showing the feasibility of the mutation operators and their capabilities in modeling real faults. Conclusion: Finally, the paper discusses the future perspectives of extending the operators to other device resource components such as Wi-Fi, NFC, and sensors, as well as automation perspectives by envisioning the implementation and validation of the mutation operators.

TL;DR: JSPreventer provides executable evidences of the not-easily-executable faults for developers, if it reveals actual errors by testing the mutated applications, and can help developers validate reliable real-world Ajax applications.

TL;DR: A set of new Java Script mutation operators are proposed to address features like variable scope, variable type etc., that are not covered by existing operators, and implemented in a tool called Mutant Tracer.

TL;DR: Google as discussed by the authors is a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext and is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems.

TL;DR: Several properties of the graph-theoretic complexity are proved which show, for example, that complexity is independent of physical size and complexity depends only on the decision structure of a program.

TL;DR: In this paper, a graph-theoretic complexity measure for managing and controlling program complexity is presented. But the complexity is independent of physical size, and complexity depends only on the decision structure of a program.

TL;DR: Several of Chidamber and Kemerer's OO metrics appear to be useful to predict class fault-proneness during the early phases of the life-cycle and are better predictors than "traditional" code metrics, which can only be collected at a later phase of the software development processes.
