Since I started writing my NUnit asserts using Assert.That* instead of Assert.Are*, I’ve been hooked on the new syntax. The constraint API makes asserts readable and helps you specifying the expected and actual values at their proper places. One thing that always displeased my eye for perfection,…
I’ve been praising the “new” Assert.That syntax, since introduced in NUnit 2.4. Expressing your tests using a constraint based API, rather than the old Are* and Is* API, makes reading your tests piece of pie. Take a look at the following test sample: var result = "Hello…
A former college of mine told me, that he had founded “The association opposed the abandonment of PerformanceDude.com”. In order to make him happy, I thought that I would leave the wonderful world of unit testing for a moment, in the benefit of writing a performance related post 🙂 We’…
I’m usually writing about unit testing but hey, you want to test your lower layers as well. If you design your application with low coupling and test in mind, all of your layers but the data layer, can be tested with unit testing. You need to write some integration…
This is my first blog post about unit testing. And so, without further ado here’s a small utility I wrote the other day. Problem Attributes in .NET as well as annotations in Java are great. I simply love the strengths of action filters in ASP.NET MVC, which are…

When searching, Chrome will start background-loading the first URL in the search result. If you choose to click the URL, the…
Most of us (me included) don’t think much about the way DNS works. Browsers, on the other hand, use DNS pretty much every day. For the uninformed, I will start by explaining how DNS works. If you already know this, feel free to skip the following paragraph. As you…
We’ve briefly touched this subject a number of times already. Making your JavaScript and CSS external simply means moving it from your HTML header to their own files, referenced as an external file in the header. So why does Yahoo think that this is a good idea? We’ve…
A lot of new stuff is released by Google these days. The Google I/O conference typically means a bunch of new products and API’s and this year are no different. In regards to performance optimization, I was very happy to discover a new Page API earlier today. That’…
