Automated Web Applications Testing

Unit tests are a vital part of several software development practices and processes such as Test-First Programming, Extreme Programming and Test-Driven Development. This article shortly presents the software quality and testing concepts as well as an introduction to an automated unit testing framework for PHP web based applicationssoftware quality, continuous integration, unit testing

Moving Usability Testing onto the Web

Abstract: In order to remotely obtain detailed usability data by tracking user behaviors within a given web site, a server-based usability testing environment has been created. Web pages are annotated in such a way that arbitrary user actions (such as "mouse over link" or "click back button") can be selected for logging. In addition, the system allows the experiment designer to interleave interactive questions into the usability evaluation, which for instance could be triggered by a particular sequence of actions. The system works in conjunction with clustering and visualization algorithms that can be applied to the resulting log file data. A first version of the system has been used successfully to carry out a web usability evaluation

How the web continues to fail people with disabilities

The digital divide is most often understood as that between the IT haves and have-nots. However, if there is one minority group that can be, and often is excluded from the world wide web, even if they have a computer, it is disabled people. The Special Educational Needs and Disabilities Act 2001 (SENDA) extended the provisions within the Disability Discrimination Act 1995 regarding the provision of services to the education sector. Yet accessible web design, dependent on professional coding standards, adherence to guidelines, and user testing, remains rare on the web. This paper examines the background to professional coding standards, and adherence to guidelines, in an attempt to find out why the web continues to fail people with disabilities. It begins by examining the progress of the transition in the 1990s from old style HTML to strict XHTML. It applauds the vision behind that transition, charts its progress identifying the principle constituencies that it involves – and how well each has played its part. It then focuses on the further problem of the requirement for user testing to iron out anomalies not covered by standards and guidelines. It concludes that validating XHTML code is desirable, but that user testing also needs to be undertaken. It identifies the complex and heterogeneous network of interrelated concerns through which the needs of disabled web users remain unheeded. To support its argument, the paper details the results of two studies – 1) of the homepages of 778 public bodies and blue chip companies, which found only 8% of homepages validated against any declared Document Type Declarations (DTD), and 2) a wider research project on employment websites which also included disabled user testing and a number of focus groups and interviews with disabled users and web development companies

Web Service Testing and Usability for Mobile Learning

Based on the summary of recent renowned publications, Mobile Learning (ML) has become an emerging technology, as well as a new technique that can enhance the quality of learning. Due to the increasing importance of ML, the investigation of such impacts on the e-Science community is amongst the hot topics, which also relate to part of these research areas: Grid Infrastructure, Wireless Communication, Virtual Research Organization and Semantic Web. The above examples contribute to the demonstrations of how Mobile Learning can be applied into e-Science applications, including usability. However, there are few papers addressing testing and quality engineering issues – the core component for software engineering. Therefore, the major purpose of this paper is to present how Web Service Testing for Mobile Learning can be carried out, in addition to re-investigating the influences of the usability issue with both quantitative and qualitative research methods. Out of many mobile technologies available, the Pocket PC and Tablet PC have been chosen as the equipment; and the OMII Web Service, the 64-bit .NET e-portal and the GPS-PDA are the software tools to be used for Web Service testing

Semantics-based Automated Web Testing

We present TAO, a software testing tool performing automated test and oracle generation based on a semantic approach. TAO entangles grammar-based test generation with automated semantics evaluation using a denotational semantics framework. We show how TAO can be incorporated with the Selenium automation tool for automated web testing, and how TAO can be further extended to support automated delta debugging, where a failing web test script can be systematically reduced based on grammar-directed strategies. A real-life parking website is adopted throughout the paper to demonstrate the effectivity of our semantics-based web testing approach.Comment: In Proceedings WWV 2015, arXiv:1508.0338

The SPIRIT collection: an overview of a large web collection

A large scale collection of web pages has been essential for research in information retrieval and related areas. This paper provides an overview of a large web collection used in the SPIRIT project for the design and testing of spatially-aware retrieval systems. Several statistics are derived and presented to show the characteristics of the collection

Automating property-based testing of evolving web services

Web services are the most widely used service technology that drives the Service-Oriented Computing~(SOC) paradigm. As a result, effective testing of web services is getting increasingly important. In this paper, we present a framework and toolset for testing web services and for evolving test code in sync with the evolution of web services. Our approach to testing web services is based on the Erlang programming language and QuviQ QuickCheck, a property-based testing tool written in Erlang, and our support for test code evolution is added to Wrangler, the Erlang refactoring tool. The key components of our system include the automatic generation of initial test code, the inference of web service interface changes between versions, the provision of a number of domain specific refactorings and the automatic generation of refactoring scripts for evolving the test code. Our framework provides users with a powerful and expressive web service testing framework, while minimising users' effort in creating, maintaining and evolving the test model. The framework presented in this paper can be used by both web service providers and consumers, and can be used to test web services written in whatever language; the approach advocated here could also be adopted in other property-based testing frameworks and refactoring tools
