Adding unit testing to an existing asp.net web forms application

Question

I have an existing asp.net webforms application that I would like to add some unit testing to but am unsure of exactly how to go about it.

The application is databas

Answer 1

For database related unit testing we use a seperate and stable test database to execute unit tests against.

We also wrap data modification tests in a TransactionScope that is not commited, therefor rolling back the data changes for subsequent test runs. We've found this works really well.
