Comparing Costs of Browser Automation Test Tools with Manual Testing

Grape, Victor January 2016 (has links)
Testing is a necessary component of software development, but it is also an expensive one, especially if performed manually. One way to mitigate the cost of testing is to implement test automation, where the test cases are run automatically. For any organisation looking to implement test automation, the most interesting cost is time. Automation takes time to implement and one of the most obvious benefits of automation is that the automated test execution time is lower than that of manual execution. This thesis contains a literature study covering testing methodology, especially in regards to the domain of web application testing. The literature covered also included three economic models that may be used to calculate the costs of automation compared to manual testing. The models can be used to calculate the time it would take, or the number of necessary executions, for the total cost of test automation to be lower than of that of manual testing. The thesis is based on a case study of test automation for the StoredSafe platform, a web application. Three sets of test automation frameworks were used to implement three different test suits and the test implementation times were collected. The data collected were then used to calculate the time it would take, using the three economic models, for the cost of automated test cases to become equal to that of with manual testing. The data showed that the estimated time to reach breakeven for the three frameworks varied between 2½ and at worst 10 years, with an average of 3½ years. The models and data presented in this thesis may be used in order to estimate the cost of test automation in comparison to manual testing over longer periods of time, but care must be taken in order to ensure that the data used is correct in regards to one’s own organisation or else the estimate may be faulty.

However, the security assurance of these resources has become an elementary task. The structure of dynamic websites composed by a set of objects such as HTML tags, script functions, hyperlinks and advanced features in web browsers may provide numerous resources and interactive services, for instance e-commerce, Internet banking, social networking, blogs, forums, among others. On the other hand, these features helped to increase the potential security risks and attacks, which are the results of malicious codes injection. In this context, Cross-Site Scripting (XSS) is highlighted at the top of the lists of the greatest threats to web applications in recent years. This work presents a method based on supervised machine learning techniques to detect XSS in web pages. A set of features extracted from URL contents and web document are employed in order to discriminate XSS patterns and to successfully classify both malicious and non-malicious pages / As aplicações web atualmente representam um importante ambiente de acesso aos serviços oferecidos na Internet.

Interoperabilitet: En väg till samordnade transporter? / Interoperability: An approach to coordinated transports?

Larsson, Niklas, Carlsson, Alexander, Levin Brunell, Alexander January 2017 (has links)
Digitaliseringens utveckling genomsyrar stora delar av samhället där informationsteknologi bidragit till tidigare otänkbara möjligheter och fördelar. I dagsläget har organisationer rationaliserat flertalet affärsprocesser där teknologin anses utgöra en fundamental utgångspunkt. Informationsteknologins framfart medför förändringar kring kommunikation där begreppet interoperabilitet introduceras som: samverkan mellan två eller fler system med motivet att utbyta information. Vidare har cirkulär ekonomi erhållit mer uppmärksamhet under senare år där motivet är att förbättra problematiken kring resurshantering och återvinning. Den här studien syftar till att skapa grunden för utformningen av ett informationssystem med stöd av ett interoperabilitetsramverk där motivet är att understödja verksamheter vid sambokningstransporter. Det här har genomförts med hjälp av en kvalitativ forskningsansats där intervjuer har nyttjats som datainsamlingsmetod där studien har avgränsats till mikro-, små- och medelstora organisationer. Dessa är belägna inom en glest befolkad kommun i Sverige där företagsrepresentanter från Orust kommun bidragit med empirisk data. / The evolution of digitization permeates large parts of society where information technology has contributed to previously unthinkable possibilities and benefits. At present, organizations have rationalized most business processes where technology is considered to be a fundamental starting point. The advancement of information technology brings about changes in communication where the concept of interoperability is introduced as: collaboration between two or more systems with the purpose of exchanging information. In addition, circular economics have gained more attention in recent years, the purpose of which is to improve the problem of resource management and recycling. This study aims to provide the basis for the design of an information system, supported by an interoperability framework, with the purpose of supporting co-transport activities. This has been done using a qualitative research effort where interviews have been used as a data collection method in which the study has been delimited to micro, small and medium-sized organizations. These are located within a sparsely populated municipality in Sweden, where business representatives from Orust Municipality contributed empirical data.

A web-based application for data visualisation and non-linear regression analysis including error calculation for laboratory classes in natural and life sciences

Keller, Titus, Kowerko, Danny 02 March 2018 (has links) (PDF)
In practical laboratory classes students traditionally receive data by reading from a measurement device (ruler, clock, voltmeter, etc.) or digitally as files in exchange formats such as CSV (comma separated value). In many cases these data have to be processed later using non-linear regression, here referred to as curve fitting. Therefore, analog data first have to be digitalised and imported to a data analysis and visualisation program, which is often commercial and requires installation. In this paper we present an alternative concept fusing open-source community tools into a single page web application facilitating data acquisition, visualisation, analysis via non-linear regression and further post processing usable for error calculations. We demonstrate the e-learning potential of this web application accessible at curvefit.tu-chemnitz.de in the context of acquired data as typically obtained in physical laboratory classes from undergraduate studies. A prototype workflow for the topic 'specific electric resistance determination' is presented along with a technical description of the basic web technology used behind. Restrictions, such as limited portability or cumbersome ways to share results electronically between student and supervisor as occurring in traditional software applications are overcome by enabling export via URL. The discussion is complemented by thorough comparison of curve fitting web applications with focus on their capability to be adaptable to user-specific models (equations) as faced by (undergraduate) students in the context of their education in laboratory classes in natural and life sciences, such as physics, biology and chemistry.

Usability : Through the use of guidelines and user participation / Användbarhet : Genom riktlinjer och användardeltagande

Mark, Emil January 2012 (has links)
The Department of Engineering Science at University West in Trollhättan was in need of a new system for scheduling personnel, as the existing system is based upon an Excel-file and is hard to work with and does not provide an easy way for the users to collaborate.The purpose of this study was to examine how existing principles and guidelines regarding interface design can be used to create a new web based system with a high usability. The purpose is also to examine how participatory design affects the design process and outcome.To create a system with a high grade of usability, a number of existing rules and guidelines regarding usability and a number of subjects regarding interaction design, were used by the development team as tools.Even though the study showed that usability guidelines can be a valuable tool and provide a good foundation it is important to emphasize the use of other techniques. For example the use of participatory design, which in the study was found to be of great value to the development team. / Institutionen för ingenjörsvetenskap vid Högskolan Väst i Trollhättan var i behov av ett nytt tjänsteplaneringssystem då det nuvarande system som är Excel-baserat är svårt att arbeta med och ej erbjuder något effektivt sätt för användarna att samarbeta.Syftet med studien var att studera hur de principer och riktlinjer som finns gällande interaktionsdesign kan användas för att skapa ett nytt webbaserat system. Syftet var också att undersöka hur deltagande design påverkar design processen och dess resultat.För att skapa ett system med en hög grad användarbarhet har ett antal regler och riktlinjer som berör användarbarhet och ett antal begrepp inom interaktionsdesign använts av utvecklingslaget som verktyg.Även om studien visar att användning av användarbarhetsriktlinjer kan vara ett värdefullt verktyg och erbjuda en god grund är det viktigt att använda fler tekniker. Till exempel användandet av deltagande design, som i studien har funnits vara av stort värde för utvecklingslaget.

Platt Hierarki : Metoder för omvandling av relationsdata till hierarkisk data

Grönblad, Carl, Eker, Magnus January 2011 (has links)
The relational database model was defined in the 1970‟s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities.  If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.   To investigate the conversion methods, case studies has been conducted on the basis of a specific organization‟s hierarchical structure. Web based prototypes were developed in Silverlight to evaluate the conversion of a hierarchical structure, based on the organization that was represented in a relational database. Existing tools were used in order to extract data from a database and transfer data in a client-server architecture.  The result is a framework for the conversion of relational data into hierarchical structure and describes the process step by step. A conversion process includes the design of the database source, extraction and transfer of data to a web client and the algorithm for performing the conversion into a tree structure. / Relationsdatabaser definierades på 1970-talet och är den dominerande databastypen idag. Skillnaden mellan data i en relationsdatabas och en hierarkisk datastruktur är att relationsdatabasen sparar poster i tabeller. Poster i tabellerna behöver ingen inbördes ordning, men kan omfatta  kopplingar i form av relationer till andra poster. En hierarkisk struktur organiserar data i form av trädstruktur och återfinns till exempel i organisationsstrukturer där olika nivåer innefattar olika ansvarsområden.  Om data som sparats i en relationsdatabas skall visas upp hierarkiskt krävs en omvandling av datastrukturen. Syftet med uppsatsen är att redogöra för hur en sådan omvandling kan utföras.  För att utreda omvandlingsmetoder har fallstudier bedrivits utifrån en specifik organisations hierarkiska struktur. Webbaserade prototyper utvecklades i Silverlight för att utvärdera omvandling till hierarkisk struktur utifrån organisationen som fanns representerad i en relationsdatabas.  Till hjälp existerar verktyg för att extrahera data ur databas samt överföra data i klient-server arkitektur.  Resultatet är ett ramverk för omvandling av relationsdata till hierarkisk struktur  och beskriver processen steg för steg. En omvandlingsprocess omfattar utformning av databas för källa, extrahering och överföring av data till en webbklient samt  algoritm  för utförande av omvandling till trädstruktur.

Grafdatabas: Från data till förståelse / Graph Database: From Data to Wisdom

Thiel, Mattias, Brandt, Pontus January 2015 (has links)
Detta examensarbete är utfört för Imano AB och behandlar ämnet databaser. Enorma mängder data finns lagrad i databaser världen över, men bara en bråkdel av all data används till något. Data kan förekomma i många olika former och en mängd olika typer av databaser har vuxit fram som komplement till de traditionella relationsdatabaserna. För sociala nätverk, logistiksystem, e-handel och i många andra sammanhang är relationer mellan dataposter ofta lika intressant som själva datainnehållet. När så är fallet kan grafdatabaser vara ett intressant alternativ. I en grafdatabas sparas relationer mellan enskilda dataposter som egna objekt, och denna egenskap kan användas för att ställa frågor om hur data relaterar till andra data. För att på ett effektivt sätt kunna utnyttja grafdatabasens egenskaper finns behov för ett lättillgängligt och användbart verktyg. Syftet med examensarbetet är att skapa ett verktyg, som kombinerar grafdatabasen Neo4js förmåga att hantera relationer mellan enskilda dataposter med visuell presentation av data i en webbapplikation. Studien undersöker om detta verktyg gör att användaren lättare kan få ny förståelse ur befintlig data. Denna studie är i grunden ett utvecklingsarbete som följer principerna för metoden Design Science Research. Metoden består av en utvecklingsprocess i flera steg där empirin är den kunskap som erhålls under arbetets gång. I utvecklingsprocessen ingår även kvalitativa undersökningsmetoder för att samla in data vid demonstration och utvärdering av artefakten. I rapporten jämförs grafdatabaser med relationsdatabaser. Studien avser dock endast att peka på skillnader gällande vissa egenskaper och genomför ingen fullständig jämförelse av exempelvis prestanda. Studien visar enligt utvecklarna att grafdatabasen Neo4j har egenskaper som gör den lämplig för användning där relationer mellan enskilda dataposter är viktiga som källor till kunskap. Resultatet av forskningen är att ny förståelse kan komma ur befintlig data genom användning av grafdatabas, speciellt om den kombineras med visualisering. / This thesis written in swedsh is done for Imano AB and deals with the subject databases. Huge amounts of data are stored in databases worldwide, but only a fraction of all the data is used. Data can exist in many different forms and various types of databases have emerged as a complement to the traditional relational databases. In social networking, logistics systems, e-commerce and many other contexts, relationships between data items are often as interesting as the actual data content. When this is the case, graph databases provide solutions to problems that other databases cannot handle. In a graph database relationships between individual data records are stored as own objects. Thanks to this, it is easier to ask questions about how data relate to other data. To effectively exploit the graph database’s features there is a need for an accessible and useful tool. The purpose of the project is to create a tool that combines the graph database Neo4j’s ability to manage relationships between individual data items with visual presentation of data in a web application. The study examines whether this tool allows the user to more easily gain new insights from existing data. This study is basically a software development process which follows the principles of the method of Design Science Research. The method consists of a development process in several stages where empirical data is the knowledge obtained during work. The development process also includes qualitative research methods to collect data at the demonstration and evaluation of the artifact. The study shows, according to the developers that the graph database Neo4j has properties that make it suitable for use where relationships between individual data items are important as sources of knowledge. The result of the research is that new understanding can emerge from existing data using a graph database, especially when combined with visualization
