Can you build your own MSTEST DataSource

I have been looking for a way to build my own DataSource for data driven unit tests in MSTEST. I have not 开发者_运维技巧found any documentation how to do this or any base class or interface that I need to implement. Any ideas?

I'm looking at building something similar to FITNesse but using Team Foundation Server for my backing store.

This is the response i got from Mathew Aniyan at Microsoft

Unfortunately the data source mechanism is not extensible. I will add a feature request to make this extensible. This will not make it into VS 2010.

Currently, with MsTest v2, a custom data source for a data driven test method is something that is very easy to handle.

As well, a working demo code can be tried from https://github.com/matei-tm/howto-demos/tree/main/MstestCustomDataSource
