A virtualized test automation framework: A DellEMC case study of test automation practice

As software development life-cycles continue to shorten, the need for reliable, maintainable and scalable test automation solutions becomes more and more important. This importance arises as software, test and automation activities occur earlier in the development life cycle with the aim of providing accelerated feedback on the code and software produced. In this environment, infrastructure and development environments are made available earlier to test teams, the demand of which can create environment bottlenecks as software and automation teams also require the same resources at the same time. To help maximize the use of the underlying resources virtualization and cloud based solutions have been proposed. However, at present there is no guidance on how to design and implement a test automation solution that leverages an underlying virtualized infrastructure. In this paper a virtualized test automation framework designed and implemented by DellEMC Software Quality team in Cork, Ireland is presented along with a macro benchmark analysis of its performance over different virtualization environments.

Impediments for software test automation: A systematic literature review

Automated software testing is a critical enabler for modern software development, where rapid feedback on the product quality is expected. To make the testing work well, it is of high importance that impediments related to test automation are prevented and removed quickly. An enabling factor for all types of improvement is to understand the nature of what is to be improved. We have performed a systematic literature review of reported impediments related to software test automation to contribute to this understanding. In this paper, we present the results from the systematic literature review: The list of identified publications, a categorization of identified impediments, and a qualitative discussion of the impediments proposing a socio‐technical system model of the use and implementation of test automation.     

Using component metadata to regression test component‐based software

Increasingly, modern‐day software systems are being built by combining externally‐developed software components with application‐specific code. For such systems, existing program‐analysis‐based software engineering techniques may not directly apply, due to lack of information about components. To address this problem, the use of component metadata has been proposed. Component metadata are metadata and metamethods provided with components, that retrieve or calculate information about those components. In particular, two component‐metadata‐based approaches for regression test selection are described: one using code‐based component metadata and the other using specification‐based component metadata. The results of empirical studies that illustrate the potential of these techniques to provide savings in re‐testing effort are provided. Copyright © 2006 John Wiley & Sons, Ltd.

An empirical study of regression test application frequency

Regression testing is an expensive process used to revalidate modified software. Regression test selection (RTS) techniques reduce the cost of regression testing by selecting a subset of a test suite. Many RTS techniques have been proposed, and studies have shown that they produce savings; other studies have shown that their cost‐effectiveness varies with characteristics of the workloads to which they are applied. It seems plausible, however, that another factor that impacts RTS techniques involves the process by which they are applied. In particular, issues such as the frequency with which regression testing is performed affect the techniques. Thus, in earlier work an experiment was conducted to assess the effects of test application frequency on the cost‐effectiveness of RTS techniques. The results exposed tradeoffs to consider when using these techniques over a series of releases. This work, however, was limited in external validity; in particular, the programs studied were relatively small. Thus, the previous experiment has been replicated on a large, multi‐version program. This second experiment confirms the findings of the first. In particular, the cost of using safe RTS techniques was strongly and negatively affected by testing interval. Conversely, the effectiveness of minimization RTS techniques was strongly and positively affected. Copyright © 2005 John Wiley & Sons, Ltd.
