Design och utvärdering av anpassningsbara webbplatser: en fallstudie
Jasmin Krhan
Grundnivå (16hp)
kl 13:00, Alan Turing (På svenska)
I takt med att användningen av smarta mobiler och handhållna enheter ökar, så ställs det idag helt andra krav på design och prestanda av webbplatser än för bara 5-6 år sedan. En webbplats visas idag från flera olika enheter och skärmstorlekar. Detta medför att en webbplats primärt utvecklad för en pc-skärm, troligtvis inte är så användbar när den visas från en mobil eller handhållen enhet
Den här rapporten i form av en fallstudie försöker svara på vilka delar av den mobila användbarhetstestningen som kan automatiseras. I rapporten beskrivs även olika teknikval och deras påverkan på en webbplats prestanda.
Det visade sig baserat på denna fallstudie att vissa delar utav den mobila användbarheten går att utvärdera utan användare. Det finns delar som inte går att automatisera och måste utvärderas förhand. När det kommer till teknikval och deras implementation på en webbplats så visar det sig i rapporten att alla teknikval inte lämpar sig i alla situationer.

Link Extraction for Crawling Flash on the Web
Daniel Antelius
Avancerad (30hp)
kl 13:15, Alan Turing (In English)
The set of web pages not reachable using conventional web search engines is usually called the hidden or deep web. One client-side hurdle for crawling the hidden web is Flash files.

This thesis presents a tool for extracting links from Flash files to enable web crawling. The files are both parsed and selectively interpreted to extract links. The purpose of the interpretation is to simulate the normal execution of Flash in the Flash runtime of a web browser. The interpretation is a low level approach that allows the extraction to occur offline and without involving automation of web browsers. A virtual machine is implemented and a set of limitations is chosen to reduce development time and maximize the coverage of interpreted byte code.

Out of a test set of about 3500 randomly sampled Flash files the link extractor found links in 34% of the files. The resulting estimated web search engine coverage improvement is almost 10%.

Design and Implementation of the ModelicaML Code Generator Using Acceleo 3.X
Ibrahim Bumin Kara
Avancerad (30hp)
kl 13:30, Donald Knuth (In English)
In today’s fast paced changing technology world, it is essential to adapt the new technologies and standards in order to stay compliant with the market. Software development is one of those key areas that have been growing highly fast and thus the need for staying up to date needs to be acknowledge by everyone in the area. The technology focused in this project is called ModelicaML[1] which is an integrated system modeling environment based on standardized languages such as UML[2] and Modelica[3]. Modelica Modeling Language (ModelicaML) is a graphical modeling language used for the description of time-continuous and time-discrete/event-based system dynamics. Currently, a ModelicaML code generator – that generates Modelica code from UML models – is implemented using the old Acceleo framework[4]. Within this thesis, the ModelicaML code generator was re-factored and implemented by using the latest Acceleo version 3.X[5]. The differences between the old and new Acceleo framework was also given an evaluation in the study in order to provide a hint of its future use for further improvements of the code generator.

The number of web applications continues to grow rapidly. Many applications that were traditionally desktop-based such as word processors, email clients or even file managers have now their web alternatives that often have bigger user base.
While the software world is shifting from providing desktop-based applications to offering cloud-based services, challenges arise to provide high quality software in this radically different environment.
Web-based applications are different in many aspects to their desktop equivalents. Web-based and desktop-based applications have radically dissimilar architecture, user interface, execution environment, requirements and limitations. To mention a few specific differences: the web application is executed in the context of a web browser, not operating system; code is executed in two separate places: on the server and in the web browser; code for the server is written in a different language than code for the client.
Because of these differences, the traditional software testing techniques are only of limited use. To properly test a web application one needs to take into account numerous differences in Web-Browsers such as Internet Explorer, Mozilla Firefox, Google Chrome or Apple Safari. Simple input-output testing is useful only to limited degree, because output cannot be just compared to the predefined value but must be compared within the context of all the environments and operating systems the application supports. The fact that an application works in one browser does not guarantee that it will work at all in other browsers.
The entire complexity of the problem makes testing web applications a very time consuming and difficult task. Often it takes significantly longer time to test the application than it is to implement it. Because of these difficulties, web applications are often tested exclusively manually by humans, and only to a limited degree. New techniques and technologies are necessary to approach the problem of web application testing.
This paper includes a case study carried out during author’s work on a web-based application. It examines the current state-of-the-art of web application testing and suggests useful techniques in tackling the problem.
