Declarative GUI Programming in Microsoft Windows

"Software technology" will provide concise, hands-on information on hot software technologies early in their life cycle. Its objective is to promote sharing of technology experiences from a user perspective. We'll look at promising software components, technologies, and development tools and ask questions about their maturity, applications, readiness, and business cases. Early adopter experience will be highlighted, including how to deal with conflicting product development standards. Our vision is to interpret the software technology hype cycle and provide down-to-earth, useful information for practitioners. The inaugural column is on GUI programming for Microsoft Windows. Although this topic isn't new-we've struggled with it for decades-both Windows and its supporting GUI technologies are changing.     

GUI testing assisted by human knowledge: Random vs. functional

Software testing is a labor-intensive task in software development life-cycle. Human knowledge is useful in the practices of software testing, especially GUI testing. There are many strategies for GUI testing assisted by human knowledge, in which manual random testing and manual functional testing are two of widely used ones. In this paper, an empirical study is conducted to compare random testing and functional testing in order to provide guidelines for GUI testing. 234 participants were recruited to create thousands of random and functional test cases for open source GUI applications. Some of these test cases were selected with certain coverage criteria and then run on GUI applications to evaluate random testing and functional testing. We study three aspects on the two testing strategies: effectiveness, complementarity and impact of test case length. Some useful observations in the empirical study are: (1) Random testing is more effective in the early stage of testing on small applications and functional testing has more extensive applicability for testing large sized applications. (2) Random testing and functional testing exhibit some complementarity in our experiment. (3) Short test cases can reveal some faults more quickly and long test cases can reveal more faults lastingly.

Employing user profiles to test a new version of a GUI component in its context of use

Advancement in reusable component technology has had a significant impact on the development of complex graphical user interfaces (GUIs), which are front-ends to most of today’s software. Software developers can, with very little effort, integrate components into their software’s GUI. Problems, however, arise when new versions of GUI components replace their predecessors in an implementation. Often, the inclusion of a new version of a component breaks some part of the software, i.e., tasks that end-users were able to perform before modifications were made can no longer be performed. Software developers (who also happen to be component users) are unable to perform adequate regression testing in this context because of several factors, including lack of source code, environmental side-effects on GUI rendering, event-driven nature of GUIs, and large number of possible permutations of events. This paper presents a new technique that end-users’ quality assurance (QA) teams can employ to test the new version of a component in its application context by using the existing version as a baseline. The technique combines lightweight event-level dynamic profiling to collect user profiles in a transparent manner, GUI reverse engineering to extract the structure of the component’s GUI, test case execution to replay the collected profiles on the new version, and GUI oracles that collect properties from the existing version. Empirical studies demonstrate the practicality, usefulness, and limitations of the technique. Atif M. Memon is an Assistant Professor at the Department of Computer Science, University of Maryland.

Pattern‐based GUI testing: Bridging the gap between design and quality assurance

Software systems with a graphical user interface (GUI) front end are typically designed using user interface (UI) Patterns, which describe generic solutions (with multiple possible implementations) for recurrent GUI design problems. However, existing testing techniques do not take advantage of this fact to test GUIs more efficiently. In this paper, we present a new pattern‐based GUI testing (PBGT) approach that formalizes the notion of UI Test Patterns, which are generic test strategies to test UI patterns over their different implementations. The PBGT approach is evaluated via 2 case studies. The first study involves 2 fielded Web application subjects; findings show that PBGT is both practical and useful, as testing teams were able to find real bugs in a reasonable time interval. The second study allows deeper analysis by studying software subjects seeded with artificial faults; the findings show that PBGT is more effective than a manual model‐based test case generation approach.     

影响GUI测试性能的两个因素:测试用例及测试预测

GUI测试在软件开发和测试中具有重要的地位.GUI自动化测试的实际应用强调了测试的成本和效率.在GUI测试中,测试用例和测试预测是两个与图形用户界面测试性能相关的主要因素.根据GUI的事件流图,事件关联图等特性,通过分析GUI事件的代码复杂度,将事件分配到各个长度不同的测试用例中,并定义测试预测的级别.通过实例,研究测试用例和测试预测对于图形用户界面测试性能的影响,从而为进一步完善GUI测试框架提供了依据.
