As Lars Fastrup pointed out in his blog entry Visual Studio Unit Tests and 64-bit SharePoint does not play the Microsoft philosophy of not providing 32-bit servers for their new platforms are going to wreak havoc on us developers, especially those that write unit tests. (if you don’t you NEED to!).
Visual Studio, the web application host, and the unit test host process are all 32-bit even if you’re running a 64-bit Operating system.
We can get around the debugging for web applications by using our local IIS process instead of the developer web host but we can’t get around running integrated unit tests.
So when you’re developing for SharePoint in a 64-bit host what do you do?
Enter NUnit.
But that makes you leave the IDE to run your unit tests right?
Nope!
Give ReSharper a try. It integrates NUnit nicely into the IDE and allows for one-click test runs.
As if integrated NUnit testing wasn’t enough the ease of working with Live Templates and Plugins should make it clear that the price of ReSharper will save you development time.
