I am currently working on some projects that are pretty large and intermingled. We have never done unit testing, and are beginning to realize that it would be a good thing to try to start but our projects have been around for a long time, and since there have been many programmers that have been in on the projects, the organization of them isn't fantastic either.
We are using VB.NET, ASP.NET and in some cases HTML5 and Silverlight. I've been looking for references on how to do unit testing, and the resources I'm finding are related to starting unit testing on existing projects. Does anybody have any good references on this?
I know that it would be worth it to start it, it's just a matter of having no idea where to start.
