How do I test my software with Visual Studio AND Large Datasets (Time Series)?

Question

I'm looking for a good reference (to a webpage or book) on testing in Visual Studio with large datasets (with the native unit testing tools in Visual Studio). (I've got Visual Studio 2008 Professional.)

There are some articles on the internet on using a database as input for testing. Only the database in that case is used for input of (single) parameter values. My project though involves methods that do calculations on long time series (of mutual fund returns) that need at least 36 months of returns for multiple mutual funds. What I'm looking for is a tutorial on how to test this project (using one or a couple of fixed data sets).

Any references?
