Testing MVC Elements and Interactions with Mock Container

Thu, 25 Jun 2009 11:08:36 GMT

Lokad Shared Libraries project includes implementation of the MockContainer that significantly simplifies testing of Model-View-Controller elements in separation. It does this by automatically generating and injecting mock objects, should the tested class ask for them in its constructor. These mock objects are persisted in the local container instance as singleton, so that additional expectations could be recorded against them. Expectations are verified when the container is disposed...

Almost every software developer dreams about starting up his own MicroISV company that would keep bringing him money even during the sleep. Let's see how cloud computing can help us out here by making it easier to succeed.

What is Version Control System (VCS)? - Wiki

Mon, 15 Jun 2009 12:46:46 GMT

Version Control System (VCS) is a software that allows to manage changes of documents, programs, images and other information that is stored in form of computer files. Changes are usually identified by an incrementing number or letter code also known as revision number or revision. The simplest usage of versioning is - you can easily go back to the previous working version of your files, should you mess something up with the latest changes. Changes could range...

Simply put, Agile Software Development is a group of software development methodologies that work...

What is Unit Testing? - Wiki

Sat, 13 Jun 2009 17:44:26 GMT

Unit Testing in software development is a way to quickly verify that smallest blocks of software (units) behave as expected even as the software changes and evolves. Here's how it works. Any program could be logically separated into distinct units (in object-oriented programming the smallest unit usually being a class). Developers, while coding these program units...

Inversion of Control - IoC - Wiki

Mon, 01 Jun 2009 19:05:37 GMT

Inversion of Control (IoC) is an approach in software development that favors removing sealed dependencies between classes in order to make code more simple and flexible. We push control of dependency creation outside of the class, while making this dependency explicit. Usage of Inversion of Control generally allows to create applications that are more flexible, unit-testable, simple and maintainable in the long run.

Case When Open Source Development Tools Are Better

Mon, 01 Jun 2009 04:33:05 GMT

We are currently using Microsoft FxCop utility as part of the continuous integration process. It statically analyzes managed .NET code assemblies and reports any potential design flaws or issues. This tool is not the most flexible one to extend, but it is a nice one to get better insight in the code without wasting a lot of time.

Component-Driven Development and IoC Containers

Sun, 31 May 2009 19:55:31 GMT

Let's try to reiterate and summarize some ideas about the Component Driven Development, IoC containers and evolving enterprise applications in general.

.NET Application Block for Validation and Business Rules

Tue, 25 Nov 2008 07:35:44 GMT

Let me introduce you to Open Source .NET Validation and Business Rules (Micro) Application Block. It is easy to get started with and allows to define reusable business and validation rules with a little of the coding overhead. Additionally it supports rule composition, validation of complex domain models, ability to modify behavior and much more.

Autofac, Lokad Shared Libraries and Silverlight 2.0

Tue, 25 Nov 2008 07:33:53 GMT

People were asking about using Autofac .NET IoC Container and Lokad Shared Libraries under the Silverlight. Well, the answer is "yes, you can do that!" See below for the latest downloads and instructions how to compile and test under Silverlight 2.0

Cloudy RetryPolicy from the Windows Azure framework

Tue, 18 Nov 2008 06:38:59 GMT

One of the little gems found in the Windows Azure SDK Sources is the RetryPolicy development pattern. It allows to define complex policies that allow you to retry on certain exceptions, retry with different limits and wait intervals. Basically, that's the things you need to build a reliable cloud computing solution. Just see the code snippet below:

RegEx and email validation in .NET

Sun, 16 Nov 2008 06:41:22 GMT

That's the email validation RegEx script I'm using. It has really high ratio for detecting bad emails and a rather good performance. string regex = @"^[a-z0-9](([_\.\-\']?[a-z0-9]+)*)@(([a-z0-9]{1,64})(([\.\-][a-z0-9]{1,64})*)\.([a-z]{2,})|(\d{1,3}(\.\d{1,3}){3}))$"; More details in the article.

How to improve .NET code by integrating hints for ReSharper

Thu, 23 Oct 2008 12:01:49 GMT

You can improve you C# .NET code by integrating hints for the ReSharper. This will give you some context actions and highlights specific for the functionality that you are writing. Precious for the API and library developers that want to be friendly for their users.

How to ensure that complex methods are covered with tests

Tue, 21 Oct 2008 20:59:52 GMT

We all do unit test coverage to monitor code areas that should be covered with the tests. However, sometimes we need more fine control, than just "Everything should be covered with tests". This could be achieved with NoCodeCoverageAttribute and unit test ensuring that it does not get applied to complex methods. Link to the open source project that has sample implementation is provided

Some performance issues and caveats of LINQ

Thu, 25 Sep 2008 04:32:15 GMT

Linq to collections generally performs worse, than the hard-coded approach. In the high-stress scenarios (i.e.: in heavy math calculations) improper Linq usage could become a problem. Let's write a couple of micro-benchmarks and compare the performance of hand-written loops with the Linq.
