I was told by a few members here that splitting up my unit tests into different assemblies for different components is the best way to structure unit tests. Now, I have a few questions about that idea.

What are the advantages of this? Organization, and isolation of errors?
Let's say I have a component named "calculator", and I create an assembly for the unit tests on "calculator". Would I create a separate assembly for the integration tests I want to run on "calculator"? Or is the definition of an integration test a test across multiple components, like "calculator" and whatever else, which would require a separate assembly to test both of them together? In that case, would I have one assembly to do all of the integration testing for every component combination?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
