• Are Singletons Evil ?
  
  In fact one member of the audience was experiencing such pain in his attempt to take legacy code base heavily utilising singletons and start to write unit tests. So whilst the majority of the time was spent examining the consequences of using the singleton pattern we also took time to highlight that one or two singletons correctly positioned in your application could in fact enable unit testing, and coding to interface without having to refactor large areas of a legacy code base. But like most things in life its not as simple as yes or no.

• NET Generics and C++ STL
  
  guess I could write a generic unit test that inspects a method and fails if it finds a boxing op codeA fellow instructor was commenting, well moaning to be exact about the fact that.NET generics were not as flexible as C++ templates. In this particular case he wanted to produce a generic Complex number type, such that he could write a single version and instantiate it for ints, doubles etc. This is trivial in C++ templates, but not so in.NET. Whilst undertaking this task there is a feature I would really like from the C# compiler and that is a pragma to turn auto boxing off.

• Custom ToString() for Flag based Enums, and a splatter of Unit Testing
  
  To extend the technique to Flag'd based enums you need to effectively test the enum value against each possible flag value. A project that I'm currently working on has a enum type, where the enum is defined like so [Flags] public enum EventDayMask { NONE = 0, SUNDAY = 1, MONDAY = 2, TUESDAY = 4, WEDNESDAY = 8, THURSDAY = 16, FRIDAY = 32, SATURDAY = 64 }   Calling ToString on a value of type EventDayMask would result in a comma separated list of the various set bits. You can't override ToString for Enum's which means you can't write your custom string generate as part of the enum class.

• Significant Advances in Unit Testing Windows Workflow
  
  This post describes a unit testing library for testing Windows Workflow Foundations. Rather it's a library that can be used in conjunction with any of these testing frameworks. Download the library with sample test project here: Kennedy.WorkflowTesting.zip (216 KB). First a Little History: Last September I posted this teaser entitled Unit Testing Coming to a Workflow Near You. In that previous post, I highlighted what I could determine to be the current state-of-the-art with regard to unit testing workflows, circa September 2008.

• Article: Avoiding 5 Common Pitfalls in Unit Testing
  
  Llewellyn Falco and I recently wrote an article for DevelopMentor's Developments newsletter entitled Avoiding 5 Common Pitfalls in Unit Testing. Avoiding 5 Common Pitfalls in Unit Testing. When I started out with unit tests, I was enthralled with the promise of ease and security that they would bring to my projects. In practice, however, the theory of sustainable software through unit tests started to break down. Unit Tests have become more trouble than they are worth.". When tests would stop working, we just ignored them.

• Unit Testing Coming to a Workflow Near You
  
  [Update: See the follow up post "Significant Advances in Unit Testing Windows Workflow" ]. However you won't find very much support for Test Driven Development (TDD) or unit testing in general. In fact the architecture that makes Windows Workflow powerful (strict separation of workflow, activities, and the host for example) really gets in the way of unit tests. There has been some work done on unit testing Windows Workflows. Here's some links: Unit Testing Activities with Windows Workflow Foundation by Ron Jacobs.

• TDD Invades Space Invaders
  
  As a follow-up to our " Avoiding 5 Common Pitfalls in Unit Testing " article we did a webcast where we took a problem from the audience and solved it live and unrehearsed on stage. The thing to remember is that all of this was done for the sole purpose of creating a recipe for a scenario we could test. Create a new test project. We made it to step 4 during our presentation (download code below) and estimate another 15 minutes would have had the whole scenario done, tested, and well-factored.

• Test-Driven Cameras
  
  wish people had this same reaction to the idea of writing code without first writing tests (TDD). Tests give you the chance: To see what you are going to write, BEFORE you write it. If you haven’t already, here’s a great place to start learning to Test-Driven Development ? If you are already writing tests, here’s a free library to make test even easier to write? Unit Testing TDDI am getting old. The other day I was hanging around with my friend, Ike Ellis. He told me a story about his kids. The first question they asked was “Where is the picture?”
