I assure the single handed composition of this master thesis only supported by declared resources. Munchen,¨ den 15. April 2013 Stefan Bleibinhaus Acknowledgments I would like to express my very great appreciation to Prof. Florian Matthes for offering me to write my thesis on such a delightful topic and showing so much interest in my work. I am particularly grateful for the assistance given by Matheus Hauder and his will to support me in my research. vii Abstract This thesis discusses the architectural design and implementation of an Enterprise 2.0 collaboration web application. The designed web application uses the concept of hybrid wikis for enabling business users to capture easily content in structured form. A Hybrid wiki is a wiki, which empowers business users to incrementally structure and classify content objects without the struggle of being enforced to use strict information structures. The emergent information structure in a hybrid wiki evolves in daily use by the interaction with its users. Whenever a user wants to extend the content, the system guides them to automatically structure it by using user interface friendly methods like auto-completion and unobtrusive suggestions based on previous similar content. -
Dynamic Data Access Object Design Pattern (CECIIS 2008)
Dynamic Data Access Object Design Pattern (CECIIS 2008) Zdravko Roško, Mario Konecki Faculty of Organization and Informatics University of Zagreb Pavlinska 2, 42000 Varaždin, Croatia [email protected], [email protected] Abstract . Business logic application layer accessing 1 Introduction data from any data source (databases, web services, legacy systems, flat files, ERPs, EJBs, CORBA This paper presents a pattern that help to desing the services, and so forth) uses the Dynamic Data Access data access layer for any data source (not just Object which implements the Strategy[1] design relational) such as CICS, JMS/MQ, iSeries, SAP, pattern and hides most of the complexity away from Web Services, and so forth. Dynamic Data Access an application programmer by encapsulating its Object (DDAO) is an implementation of the Strategy dynamic behavior in the base data access class. By design pattern [1] which defines a family of using the data source meta data, it automates most of algorithms, encapsulate each one, and make them the functionality it handles within the application. interchangeable through an interface. Application programmer needs only to implement Having many options available (EJB, Object specific „finder“ functions, while other functions such Relational Mapping, POJO, J2EE DAO, etc.) to use as „create, store, remove, find, removeAll, storeAll, while accessing a data source, including persistent createAll, findAll“ are implemented by the Dynamic storage, legacy data and any other data source, the Data Access Object base class for a specific data main question for development is: what to use to source type.. bridge the business logic layer and the data from a Currently there are many Object Relational data source ? Assuming that the data access code is Mapping products such as Hibernate, iBatis, EJB not coded directly into the business logic layer (Entity CMP containers, TopLink, which are used to bridge Bean, Session Bean, Servlet, JSP Helper class, POJO) objects and relational database. -
Ioc Containers in Spring
301AA - Advanced Programming Lecturer: Andrea Corradini [email protected] http://pages.di.unipi.it/corradini/ AP-2018-11: Frameworks and Inversion of Control Frameworks and Inversion of Control • Recap: JavaBeans as Components • Frameworks, Component Frameworks and their features • Frameworks vs IDEs • Inversion of Control and Containers • Frameworks vs Libraries • Decoupling Components • Dependency Injection • IoC Containers in Spring 2 Components: a recap A software component is a unit of composition with contractually specified interfaces and explicit context dependencies only. A software component can be deployed independently and is subject to composition by third party. Clemens Szyperski, ECOOP 1996 • Examples: Java Beans, CLR Assemblies • Contractually specified interfaces: events, methods and properties • Explicit context dependencies: serializable, constructor with no argument • Subject to composition: connection to other beans – Using connection oriented programming (event source and listeners/delegates) 3 Towards Component Frameworks • Software Framework: A collection of common code providing generic functionality that can be selectively overridden or specialized by user code providing specific functionality • Application Framework: A software framework used to implement the standard structure of an application for a specific development environment. • Examples: – GUI Frameworks – Web Frameworks – Concurrency Frameworks 4 Examples of Frameworks Web Application Frameworks GUI Toolkits 5 Examples: General Software Frameworks – .NET – Windows platform. Provides language interoperability – Android SDK – Supports development of apps in Java (but does not use a JVM!) – Cocoa – Apple’s native OO API for macOS. Includes C standard library and the Objective-C runtime. – Eclipse – Cross-platform, easily extensible IDE with plugins 6 Examples: GUI Frameworks • Frameworks for Application with GUI – MFC - Microsoft Foundation Class Library. -
Design Pattern Interview Questions
DDEESSIIGGNN PPAATTTTEERRNN -- IINNTTEERRVVIIEEWW QQUUEESSTTIIOONNSS http://www.tutorialspoint.com/design_pattern/design_pattern_interview_questions.htm Copyright © tutorialspoint.com Dear readers, these Design Pattern Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of Design Pattern. As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer: What are Design Patterns? Design patterns represent the best practices used by experienced object-oriented software developers. Design patterns are solutions to general problems that software developers faced during software development. These solutions were obtained by trial and error by numerous software developers over quite a substantial period of time. What is Gang of Four GOF? In 1994, four authors Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides published a book titled Design Patterns - Elements of Reusable Object-Oriented Software which initiated the concept of Design Pattern in Software development. These authors are collectively known as Gang of Four GOF. Name types of Design Patterns? Design patterns can be classified in three categories: Creational, Structural and Behavioral patterns. Creational Patterns - These design patterns provide a way to create objects while hiding the creation logic, rather than instantiating objects directly using new opreator. This gives program more flexibility in deciding which objects need to be created for a given use case. Structural Patterns - These design patterns concern class and object composition. Concept of inheritance is used to compose interfaces and define ways to compose objects to obtain new functionalities. -

CITS5501 Software Testing and Quality Assurance Test Automation
Test automation Test cases CITS5501 Software Testing and Quality Assurance Test Automation Unit coordinator: Arran Stewart 1 / 111 Test automation Test cases Re-cap We looked at testing concepts – failures, faults/defects, and erroneous states We looked at specifications and APIs – these help us answer the question, “How do we know what to test against?” i.e., What is the correct behaviour for some piece of software? We have discussed what unit tests are, and what they look like 2 / 111 Test automation Test cases Questions What’s the structure of a test? How do different types of test relate? How do we come up with tests? How do we know when we have enough tests? What are typical patterns and techniques when writing tests? How do we deal with difficult-to-test software? (e.g. software components with many dependencies) What sorts of things can be tested? 3 / 111 Test automation Test cases Questions What’s the structure of a test? Any test can be seen, roughly, as asking: “When set up appropriately – if the system (or some part of it) is asked to do X, does its actual behaviour match the expected behaviour?” 4 / 111 Test automation Test cases Test structure That is, we can see any test as consisting of two things: Test values: anything required to set up the system (or some part of it), and “ask it do” something, and observe the result. Expected values: what the system is expected to do. “Values” is being used in a very broad sense. Suppose we are designing system tests for a phone – then the “test values” might include, in some cases, physical actions to be done by a tester to put the phone in a particular state (e.g. -
Inversion of Control in Spring – Using Annotation
Inversion of Control in Spring – Using Annotation In this chapter, we will configure Spring beans and the Dependency Injection using annotations. Spring provides support for annotation-based container configuration. We will go through bean management using stereotypical annotations and bean scope using annotations. We will then take a look at an annotation called @Required, which allows us to specify which dependencies are actually required. We will also see annotation-based dependency injections and life cycle annotations. We will use the autowired annotation to wire up dependencies in the same way as we did using XML in the previous chapter. You will then learn how to add dependencies by type and by name. We will also use qualifier to narrow down Dependency Injections. We will also understand how to perform Java-based configuration in Spring. We will then try to listen to and publish events in Spring. We will also see how to reference beans using Spring Expression Language (SpEL), invoke methods using SpEL, and use operators with SpEL. We will then discuss regular expressions using SpEL. Spring provides text message and internationalization, which we will learn to implement in our application. Here's a list of the topics covered in this chapter: • Container configuration using annotations • Java-based configuration in Spring • Event handling in Spring • Text message and internationalization [ 1 ] Inversion of Control in Spring – Using Annotation Container configuration using annotation Container configuration using Spring XML sometimes raises the possibility of delays in application development and maintenance due to size and complexity. To solve this issue, the Spring Framework supports container configuration using annotations without the need of a separate XML definition. -

Proof of Concept (Poc) Selenium Web Driver Based Automation Framework
e-ISSN (O): 2348-4470 Scientific Journal of Impact Factor (SJIF): 4.72 p-ISSN (P): 2348-6406 International Journal of Advance Engineering and Research Development Volume 4, Issue 7, July -2017 Proof of concept (Poc) selenium web driver based Automation framework B AJITH KUMAR Master of science ( Information Technology ) Department of Mathematics COLLEGE OF ENGINNERING GUINDY (CEG) Anna university ABSTRACT: To control test execution time. Software testing is a process of executing a program or application with the intent of finding the software bugs. It can also be stated as the process of validating and verifyingthat a software program or application or product: Meets the business and technical requirements that guided it’s design and development. Works as expected. KEY WORDS: SOFTWARE TESTING .AUTOMATION TESTING ,SELENIUM, SELENIUM WEBDRIVER ,AGILE TESTING , TESTNG Test automation : In software testing, test automation is the use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or add additional testing that would be difficult to perform manually. AGILE TESTING : A software testing practice that follows the principles of agile software development is called Agile Testing. Agile is an iterative development methodology, where requirements evolve through collaboration between the customer and self- organizing teams and agile aligns development with customer needs. Selenium automation tool Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. -
