Unit testing with singletons

manpreet Best Answer 2 years ago

I have prepared some automatic tests with the Visual Studio Team Edition testing framework. I want one of the tests to connect to the database following the normal way it is done in the program:

string r_providerName = ConfigurationManager.ConnectionStrings["main_db"].ProviderName;

But I am receiving an exception in this line. I suppose this is happening because the ConfigurationManager is a singleton. How can you work around the singleton problem with unit tests?

Thanks for the replies. All of them have been very instructive.
