The document discusses the Model-View-ViewModel (MVVM) design pattern. It describes MVVM as a pattern created in 2005 for building user interfaces that separates an application's business logic and data (the model) from its user interface (the view). The view model acts as an intermediary between the view and model, handling view logic and making data from the model available to the view. The document also discusses advantages like separation of concerns and easier testing, as well as disadvantages like complexity with larger applications. It then introduces Android Data Binding as a way to minimize glue code between views and view models through declarative bindings.
Taligent is developing a new programming model called Model-View-Presenter (MVP) based on the Model-View-Controller (MVC) model of Smalltalk. MVP provides a design methodology for application and component development. It separates programs into data management and user interface aspects. Taligent will provide frameworks to help developers implement MVP concepts like models, views, selections and commands in IBM's VisualAge programming environments.
Unit testing involves developers writing short tests of individual units or modules of code as they develop software. These tests automatically validate that each piece of the software performs as intended. Benefits of unit testing include finding bugs earlier, simplifying integration, facilitating change, and encouraging good design. Developers should write tests early and often, refactor code frequently to keep it simple, and fix bugs as soon as they are discovered. Checklists can help ensure unit tests cover important functionality.
The document discusses a presentation by Stephen Walther on ASP.NET MVC. It provides an overview of ASP.NET MVC, describing it as Microsoft's newest framework for building web applications. It discusses the core components of MVC - the model, view and controller. It also outlines several walkthroughs for building a contact manager application in ASP.NET MVC, including implementing CRUD operations, validation, refactoring using design patterns, and adding unit tests and Ajax. Resources for further learning about ASP.NET MVC are also provided.
Android-centric-architecture vs. unit testable appsPaul Wein

17 Ways to Save Time on Manual Cross Browser TestingSarah Elson
One of the major hurdles that web-developers, as well as app developers, face is ‘Testing their website/app’ across different browsers. The testing mechanism is also called as ‘Cross-Browser Testing’. There are so many browsers and browser versions (Google Chrome, Mozilla Firefox, Internet Explorer, Microsoft Edge, Opera, Yandex, etc.), numerous ways in which your website/app can be accessed (via desktop, smartphones, tablets, etc.) and numerous operating systems (Windows, MacOS, Linux, Android, iOS, etc.) which might be used to access your website.
Types of software documentation include packaging, marketing materials, warranties, end user license agreements, labels, installation instructions, user manuals, online help, tutorials, samples, examples, and error messages. Software documentation is an important part of the overall software product that users interact with. Good documentation improves usability, reliability, and lowers support costs by helping users understand and correctly use the software. As a software tester, documentation should be treated with the same level of attention and testing as the code itself to ensure a high quality overall product.
Design patterns are reusable solutions to common software design problems. There are three main types of design patterns: creational patterns, which create objects for you rather than having you instantiate them directly; structural patterns, which help compose groups of objects into larger structures; and behavioral patterns, which help define communication between objects. Some common design patterns used in Android development include Model-View-Controller (MVC), Model-View-Presenter (MVP), and Observer. MVC separates an application into three components - the model, the view, and the controller. MVP builds on MVC by introducing a presenter component to separate the application logic and flow from the view components. The Observer pattern allows an object to publish changes to its state
Software prototyping is the process of implementing presumed software requirements to learn more about actual requirements or alternative designs. It has several phases: requirements gathering, quick design, building a prototype, user evaluation, refining the prototype, and engineering the final product. Prototyping allows for early assessment of requirements, increased user confidence, and insight for better implementation. However, it can be time consuming and expensive if many iterations are needed to satisfy the user. It also risks losing development focus or creating false expectations.
This document discusses how to develop a software prototype. It defines a prototype as a preliminary version of a software application that demonstrates the main functionality of the product under development. Prototypes come in different levels of fidelity from low to high. Low-fidelity prototypes quickly demonstrate screen mockups while high-fidelity prototypes fully simulate functionality. Prototypes can be either throwaway, meant to help discover requirements and then be discarded, or evolutionary, where an initial prototype is refined through stages. The steps to design a software prototype include gathering initial requirements, developing the prototype, reviewing it with customers, and revising/enhancing it based on feedback.
The document discusses software prototyping. It defines prototyping as building initial versions of a software application that demonstrate functionality but may not contain the full logic of the final product. This allows getting early feedback from customers to better understand requirements. Different types of prototyping are covered, including throwaway, evolutionary, incremental, and extreme prototyping. The document also reviews best practices like reviewing prototypes with stakeholders and revising based on feedback. Potential applications and pros and cons of prototyping are presented.
The prototype model involves building a working prototype of the system before full development based on user requirements. It allows users to evaluate early versions of the system and provide feedback to refine requirements. Key steps are gathering requirements, quick design of the prototype, building and refining the prototype based on user evaluations, then developing the full system based on the final prototype. Advantages include early user assessment, improved communication, and reduced risks. Disadvantages include potential delays if multiple prototypes are needed and loss of focus on full system quality.

Model-view-controller (MVC) is a software architectural pattern that separates application logic from user interface. It is commonly used for web applications and mobile applications. MVC promotes separation of concerns, where the model manages application data and logic, the view manages presentation, and the controller manages input and interaction between model and view. MVC makes applications easier to maintain and extend through loose coupling of these components.
Choosing the Right HTML5 Framework to Build your Mobile Web Application White...RapidValue
The mobility sector was mainly dominated by native technologies (Android and iOS applications) until the
rise of HTML5. For a web developer to build mobile applications can be challenging with variety of platforms
to choose from and technologies to learn. HTML is known to be an easy to learn and fast to implement
technology, and has the maximum number of web applications to its credit. However, when HTML5 was
released by the World Wide Web consortium, it came along with an added advantage in the mobility domain
i.e. cross-platform capability with a single code base. The native technologies demand a higher cost to
market, since they consist of SDKs and IDEs, and require a higher learning curve for each device platform.
HTML is a well-known technology to most of the in-house developers and the enterprises can start entering
the mobility sector right away.
HTML5 technology though gaining momentum quickly is still not quite ready to be used for complex web
applications, particularly line-of-business applications. Many frameworks built on HTML and JavaScript are
available to enable easier development. However, the web/desktop applications differ from the mobile
applications. The device capabilities and usability are a major factor while developing a mobile application.
The common questions which most of the enterprises have in mind, before building mobile applications are
which technology framework to choose to build their first mobile app and what factors to consider in making
the right choice.
This paper provides a guide for developers and solution architects to understand the different software
architecture patterns, HTML5 frameworks available to build mobile apps, pros and cons of these application
development frameworks and elements to consider for selecting the right framework, while making a
decision to build mobile web apps.

Code Camp 06 Model View Presenter Architecturebitburner93
This is the slide show I created for the first Twin Cities Code Camp in November of \'06 - I did this when I was working for Digineer and also used it in a Digi-U session that I put on for the other consultants.
The document discusses the Model-View-ViewModel (MVVM) pattern, which is a variation of the Model-View-Controller pattern that has been popular for user interface programming. MVVM was introduced by John Gossman and takes advantage of WPF's data binding infrastructure to separate application logic and user interface. It allows testing view models independently of views and supports a smooth designer/developer workflow. View models expose command objects to handle user input and implement INotifyPropertyChanged to update bound views when properties change.

Tools mentioned are Visual Studio, Resharper, xUnit, Moq and Pomodoro. References for further reading on TDD and unit testing are also provided.
MVVM Pattern
The document discusses the MVVM pattern, which is a variation of the MVC pattern introduced by the WPF team. It describes the key components of MVVM - the View, which represents the user interface and uses binding to subscribe to the ViewModel; the ViewModel, which is an abstraction of the View that acts as a connector between the View and Model; and the Model, which can be a data, domain, or service layer class. The MVVM pattern aims to remove logic from code-behind, allow independent development of the View and ViewModel, prevent duplicate code, and enable better testability. Several supporting libraries and frameworks for implementing MVVM are also listed.
The document discusses the Model-View-ViewModel (MVVM) pattern, which separates user interface, data access, and application logic. MVVM is well-suited for Microsoft XAML platforms like Silverlight and WPF. It promotes loose coupling between components, enables testability, and supports separation of developer and designer roles. The key components in MVVM are the model, view, and viewmodel, with the viewmodel acting as an intermediary between the model and view.
This document summarizes a presentation about ASP.NET Core and DotVVM. It introduces the speaker, Daniel Gomez Jaramillo, and his background.

The document discusses Struts, a Java web framework based on the MVC pattern. It covers the software crisis that frameworks address, the differences between Model 1 and Model 2 architectures, and features of Struts including its configurable MVC components, POJO-based actions, and support for AJAX, integration, results, and tags. The core Struts components of controller, model, and view are described along with the basic request-response flow when using Struts.
The document discusses architectural design patterns MVC, MVP, and MVVM. It explains that MVC separates an application into three components - the model, the view, and the controller. MVP adds a presenter layer between the model and view to avoid direct communication. MVVM uses data binding between the view and view model layers, allowing two-way communication to automatically update the view when data changes. While any pattern can be used, the author recommends MVP with data binding to reduce code and prevent mistakes.

This presentation discusses an overview of the .NET framework, a little history of C#, and the evolution of C# from its early days up to its current form including a preview of C# 7.0
This document discusses SQL versus NoSQL databases. NoSQL databases are better suited for internet-scale applications with massive amounts of data and users due to their ability to provide high availability, high performance, and horizontal scalability. NoSQL databases sacrifice strict ACID properties for looser eventual consistency in order to better serve highly distributed systems. SQL remains preferable when strict ACID properties are required. The document provides examples of MongoDB and concludes that the right database choice depends on the specific needs and use case.
Unit testing, UI testing and Test Driven Development in Visual Studio 2012Jacinto Limjap
Unit testing, UI testing, and test-driven development (TDD) are explained. Unit testing tests individual units/blocks of code, UI testing automates user interactions, and TDD uses tests to design software. Visual Studio 2012 focuses the testing experience on developers with improvements to Microsoft Test (MS-Test) framework, support for additional frameworks like NUnit and Selenium, and features like continuous testing and code coverage analysis. Demo shows how to do UI testing with Selenium and practice TDD.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
