app.configs and MSTest Project - null reference for a connection string

Question

When I try to run Unit Tests (mstest) I run into this issue.
The line of code:

_mainCnStr = System.Configuration.ConfigurationManager.
               C         


        

Answer 1

I'm assuming mstests are, like nunit tests, embedded in a seperate assembly which gets loaded by the testing application? In that case, you may need to create some test set-up code which loads in the configuration file.
