• Me, myself and design patterns

  Looks like the Silverlight related posts I’ve announced would have to wait one more blog post due to the event which happened to me today and which made me thinking about a few of the architecture related things which at the end resulted with a few of...

• Design for testability - WCF proxies

  Recently I spent some time participating in projects involving Silverlight, Prism etc and there are couple of interesting things I’ve came up with during that period which I would like to share with the community in a form of a couple of blog posts showing...

• Say no to ServiceLocator

  ( Disclaimer: As I stated here , while I find over the time ServiceLocator based code to be a bad practice, I do understand the need for its usage in certain brown-field  scenarios as a way of reducing the risk while introducing the IoC.) In my previous... Posted X 20 2009, 02:18 odp. by malovicn with | with 7 comment(s) Filed under: Architecture, Test Driven Development

• Inversion Of Control, Single Responsibility Principle and Nikola’s laws of dependency injection

  Today I stumbled upon the stack overflow question regarding using DI frameworks for classes with many dependencies where the example given and couple of answers have reminded me about a subject I want to post for a long time. So the example from question... Posted X 16 2009, 01:04 odp. by malovicn with | with 13 comment(s) Filed under: Architecture

• Dependency injection in real world

  Patrick left a comment on one of my previous blog posts asking a couple of very interesting questions that I’ve been asking myself too: Is service locator legitimate way of doing IoC? (I’ll use example code from that blog post as a base for my today blog... Posted XII 23 2008, 10:45 dop. by malovicn with | with 8 comment(s) Filed under: Architecture, Test Driven Development

• Fluent NHibernate – NHibernate without configuration files

  NHibernate is great, (no doubt about it) but every time I was supposed to work with it, the fact that I had to manually type in all those xml configuration entries was something I really didn’t like at all. The most important complains I personally have... Posted VIII 31 2008, 11:39 dop. by malovicn with | with 14 comment(s) Filed under: Architecture, Development

• Model View Presenter (MVP) – Tips from trenches (TFT) – Working with HttpContext (Part 2)

  Today’s hurdle: Using HttpContext without System.Web One of the principles I really feel strong about can be formulated like this:”Presenter is not allowed to reference System.Web assembly at all”. Main reason why I feel so strong about that, is based on the fact that once referenced System.Web enables developers in your team to use types from that assembly (HttpContext, Session, Query, Cache etc) and we all know what PITA those types can be when testing Presenters. Here’s very simple example I’ll use in today’s post: Imagine you have a presenter which based on value of some query parameter is performing some redirecting or updating UI elements. The easiest way (referencing the System.Web into presenter) will enable very easy implementation of required functionality but testing that code will require things like creating fake web context which IMHO is good sign of of important web test smell.

• Model View Presenter (MVP) – Tips from trenches (TFT) – Base types(Part 1)

  RAD tooling style Microsoft is supporting last couple of years usually leads to the code where presentation and bossiness logic are mixed and tightly coupled which makes testability, maintainability and sustainability much more harder then they should be. In case you’ve had to work in the past with web pages containing couple of thousands lines in code behind you will know exactly what problems I am referring to here. In case not, please let me know what is the name of the place where you work :) One way to tackle that is using the Model View Presenter UI design pattern which provides clean separation between UI and domain logic and as a result of that come testability of the “UI code”, SRP and SOC principles appliance, clean domain model etc… To check out rest of my MVP (Model View Presenter) blog post please visit my blog page (thanks to feedburner limit of 500K per feed) Posted VII 27 2008, 09:47 odp. by malovicn with | with 12 comment(s) Filed under: Architecture, Development
