Using C# anonymous types to assert complex results in your unit tests

Does this sounds familiar to you: You come to work early(ish) in the morning - ready to apply a new technology you've just learnt about - just to find out that you can't. Your frustration grows as you understand that in order to use this "new and shiny" some adjustments must be made and what … Continue reading Using C# anonymous types to assert complex results in your unit tests

Assert.AreEqual in MSTest – done right

Every unit testing framework out there comes with a plethora of assertion methods - this is not necessarily a good thing. Instead of writing simple code a developer is forced to choose the correct assertion method from a seemingly endless list of methods, most of which look exactly the same! Having multiple overloaded methods with … Continue reading Assert.AreEqual in MSTest – done right

That’s why I was amazed to … Continue reading Faking DateTime using Microsoft Fakes seems to be broken

The real difference between NUnit and XUnit

I’ve just started yet another pet project and wanted to pick a unit testing framework (.NET). On a soon-to-regret whim I’m tried googling “NUnit vs. XUnit” and read the first 10 posts I got. They were informative and mostly correct, unfortunately all completely missed the one big difference between those two excellent unit testing frameworks… … Continue reading The real difference between NUnit and XUnit

Comparing Two objects using Assert.AreEqual()

Anyone who ever googled (binged?) about unit testing have heard about the “one assert per test rule”. The idea is that every unit test should have only one reason to fail. It’s a good rule that help me write good, robust unit test – but like all such rules-of-the-thumb it’s not always right (just most … Continue reading Comparing Two objects using Assert.AreEqual()
