For a project I'm currently working on I need to write a Csv Parser. Simple enough, right? Well... each csv file has different parsing criteria, each has a completely different structure and data, and each manages to change its ways every now and then. Not only that, each file needs to be merged into a common schema!

I'm trying to use TDD as a method to tackle this. I'm going to have a IParser interface where the concrete implementation will take a IDataSource and an IParsingStrategy injected into it. Nevermind the code model, developing the UI that will allow a user to change the parsing strategy and persisting those changes is going to be an even bigger headache.

Watching JP Boodhoo's dnrTV episodes for inspiration.
