Chapter 16: Quality Attributes. For more details of the topics covered in this guide, see Contents of the Guide. Quality attributes are the overall factors that affect run-time behavior, system design, and user experience. They represent areas of concern that have the potential for application wide impact across layers and tiers. Some of these attributes are related to the overall system design, while others are specific to run time, design time, or user centric issues. The extent to which the application possesses a desired combination of quality attributes such as usability, performance, reliability, and security indicates the success of the design and the overall quality of the software application. When designing applications to meet any of the quality attributes requirements, it is necessary to consider the potential impact on other requirements.
You must analyze the tradeoffs between multiple quality attributes. The following table describes the quality attributes covered in this chapter. Availability Performance. Building Better Software › Using nonfunctional requirements to build better software. Understanding nonfunctional requirements — which some people call software quality attributes or nonbehavioral requirements — can make a big difference when you’re building software. But a lot of people have trouble taking a somewhat theoretical idea and applying it to a real-life project. Luckily, we’ve got an easy, practical technique to use nonfunctional requirements on a real software project.
How well does your program do… well, whatever it does? I’ve wanted to write a post about nonfunctional requirements for a while. But I’ve been trying to find a good angle for talking about them, because while they can be really practical and useful on a software project, it’s a little hard to get that practicality across in a useful way. Luckily, I’ve been spending a lot of time lately talking about architecture, since Jenny and I are going to give our Beautiful Teams talk at the ITARC New York conference next week.
And that’s got me thinking a lot about how architects work. Quality software —12 non functional requirements every app should have. If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting! Sharebar When people talk about really great quality software, they usually think in terms of it’s utility, simplicity or aesthetics. But there’s more to it than that. Great architecture comes from great constraints How I arrived at this list I started to look at this a little while back when I was putting together our playbook for how we create software for our customers by bringing together agile and user centred design together.
Performance This one shouldn’t come as a surprise. 1. How long should your app take to load? 2. Can I get a spinning beachball please? 3. This could be covered off with general reporting times, but if you’re providing an API you should probably consider acceptable query times too. Capacity and Scalability How much do you need to cope with now, and how much do you think you’ll need to cope with in the future. 4.

InRelease - Agile Release Management for TFS > Home. By using Release Management for Visual Studio 2013, your development and operations teams can enable additional capabilities in Team Foundation Server 2013 so that they can more easily and more confidently configure and automate complex deployments to a variety of target environments. You can also model release processes, track approvals and sign-offs, and display release status graphically.
Each person using the Release Management Client for Visual Studio 2013 for creating, updating, or deleting a release pipeline sequence must be licensed for either Visual Studio Ultimate with MSDN, Visual Studio Premium with MSDN, Visual Studio Test Professional with MSDN, or MSDN Platforms. To enable the release management capabilities, you must also install the Release Management Server for Team Foundation Server 2013. To model release processes and enable graphical views of release status, you must have the Release Management Client for Visual Studio 2013.

3 Predictions On The Future Of Enterprise Software. Editor’s Note: This guest post is written by Uzi Shmilovici, the founder and CEO of Future Simple, the company behind Base CRM. The first image that comes to my mind when I think about business computing is the dystopic scene from the 1984 Apple commercial: A swarm of employees wearing the same uniforms and marching in unison into their offices where they are forced to use certain devices and software. They sit down in front of their PCs, open a business application their company paid millions of dollars to implement and, in a disciplined manner, fill out forms to populate the company’s database so their managers will be happy.
The Anya Major in this dystopic scene is the consumerization of enterprise software. The term “consumerization” was first used, in the context of enterprise software, by Kevin Efrusy from Accel Partners back in 2008. Why is consumerization accelerating? There are three key paradigm shifts that accelerate the consumerization of business software: Online Payment Systems & Credit Card Payment Processing Services by Braintree.

Code University - Google Code. Testability and Entity Framework 4.0. Scott Allen Published: May 2010 Introduction This white paper describes and demonstrates how to write testable code with the ADO.NET Entity Framework 4.0 and Visual Studio 2010. This paper does not try to focus on a specific testing methodology, like test-driven design (TDD) or behavior-driven design (BDD).
Instead this paper will focus on how to write code that uses the ADO.NET Entity Framework yet remains easy to isolate and test in an automated fashion. What Is Testable Code? The ability to verify a piece of software using automated unit tests offers many desirable benefits. A good unit test suite allows a development team to save time and remain in control of the software they create. Unit testing comes with a price, however. Microsoft designed the ADO.NET Entity Framework 4.0 (EF4) with testability in mind. The Qualities of Testable Code Code that is easy to test will always exhibit at least two traits.
Public int Add(int x, int y) { return x + y; } The Repository Pattern Figure 1. Big Data. Create a Testing DSL with FitNesse and Selenium (Part 1) My team uses FitNesse extensively to create automated acceptance tests for our systems. Recently we’ve added Selenium RC running from within FitNesse to our toolbox. There’s a lot of buzz lately over the creation of Domain Specific Languages (DSL), driven in no small part to create a syntax for the application code that is readable by the business partners and testers. We accomplish the same goal (or at least try to) by using FitNesse fixtures to effectively create a DSL for our applications that our tester can use to specify and verify the expected behavior of the system. FitNesse is both the “language” parser and a reporting framework that can already be plugged into NAnt and CC.Net, so there’s no real need to create custom interpreters.
Take that you Ruby cool kids with your “missing_method” metaprogramming magic! Most of my last week and a half has been spent building the “Mother of all Automated Tests.” The DoFixture is the Lynchpin public class CreateBundleScreenFixture : DoFixture.
