Abstract
Graphical user interfaces (GUIs) have become popular as they appear in everydays' software. GUIs have become an ideal way of interacting with computer programs, making the software friendlier to its users. GUIs have grown, and so has the usage of UI Patterns featured in GUIs. UI Patterns are recurring solutions to solve common GUI design problems. We developed the notion of UI Test Patterns that, are able to test different implementations of UI Patterns. Therefore, we created a new methodology called Pattern-Based GUI Testing (PBGT) that aims at systematizing and automating the GUI testing process. PBGT samples the input space using UI Test Patterns, which provide a reusable and configurable test strategy, in order to test a GUI that was implemented using a set of UI Patterns. In this paper we present three UI Test Patterns: Login, Master/Detail and Sort. Copyright © 2014 ACM.

Abstract
A great deal of effort in model-based testing is related to the creation of the model. In addition, the model itself, while a powerful tool of abstraction, can have conceptual errors, introduced by the tester. These problems can be reduced by generating those models automatically. This paper presents a dynamic reverse engineering approach that aims to extract part of the model of an existing web application through the identification of User Interface (UI) patterns. This reverse engineering approach explores automatically any web application, records information related to the interaction, analyses the gathered information, tokenizes it, and infers the existing UI patterns via syntactical analysing. After being complemented with additional information and validated, the model extracted is the input for the Pattern-Based Graphical User Interface Testing (PBGT) approach for testing existing web application under analysis.

Abstract
Currently, software tends to assume increasingly critical roles in our society so assuring its quality becomes ever more crucial. There are several tools and processes of software testing to help increase quality in virtually any type of software. One example is the so called Model-Based Testing (MBT) tools, that generate test cases from models. However, most of these tools have a configuration phase, where test input data is provided manually by the tester, which influences the quality of the test suite generated. By adding coverage analysis to MBT tools it is possible to give feedback and help the tester to define the configuration data needed to achieve the most valuable test suite as possible. This paper presents a tool, PARADIGM-COV, that produces coverage information both over the PARADIGM model elements (to assess if input data is adequate to cover the test goals and assess if preconditions are achievable), and during test case execution (to identify the parts of the model/code that were actually exercised).

Abstract
The incorrect requirements elicitation, requirements changes and evolution during the project lifetime are the main causes pointed out for the failure of software projects. The requirements in the context of Software as a Service are in constant change and evolution which makes even more critical the attention given to Requirements Engineering (RE). The dynamic context evolution due to new stakeholders needs brings additional challenges to the RE such as the need to review the prioritization of requirements and manage their changes related to their baseline. It is important to apply methodologies and techniques for requirements change management to allow a flexible development of SaaS and to ensure their timely adaptation to change. However, the existing techniques and solutions can take a long time to be implemented so that they become ineffective. In this work, a new methodology to manage functional requirements is proposed. This new methodology is based on collecting and analysis of information about the usage of the service to extract pages visited, execution traces and functionalities more used. The analysis performed will allow review the existing requirements, propose recommendations based on quality concerns and improve service usability with the ultimate goal of increasing the software lifetime.

Abstract
This paper presents a study aiming to assess the feasibility of using the Pattern Based GUI Testing approach, PBGT, to test mobile applications. PBGT is a new model based testing approach that aims to increase systematization, reusability and diminish the effort in modelling and testing. It is based on the concept of User Interface Test Patterns (UITP) that contain generic test strategies for testing common recurrent behaviour, the so-called UI Patterns, on GUIs through its possible different implementations after a configuration step. Although PBGT was developed having web applications in mind, it is possible to develop drivers for other platforms in order to test a wide set of applications. However, web and mobile applications are different and only the development of a new driver to execute test cases over mobile applications may not be enough. This paper describes a study aiming to identify the adaptations and updates the PBGT should undergo in order to test mobile applications.
