Is it possible to restore a database at the end of every NUnit test?

Question

I'm writing a few UI automation test scripts using C#, NUnit and Selenium WebDriver. I would like to know if it's possible to restore the database at the end of each test (like via the TearDown method) and if so how I could achieve this.

I tried following this and this but they didn't seem to work. I'm guessing this is because I'm not executing any database related operation from the test script itself?

Answer 1

You can use TransactionScope

using (TransactionScope scope = new TransactionScope())
{
      //your code goes here
}

Keep in mind, that auto_increment counter values will not roll back.

Answer 2

I would recommend creating Fakes at your DAL layer so that you are always using the same data for each run and you won't have to worry about having a live connection to a database. I wrote a bit about the general idea here http://blog.dmbcllc.com/automated-web-application-functional-testing/ if you need more detail.
