  • How do I fix my Unit Test to have global access to everything?

    - by SLC
    Usually when you add one (in Visual Basic), it pops up a message asking if you want to enable an option that lets the test access things like private methods etc. However, I am editing a solution that does not have this enabled. I'd like to enable it so my unit tests will work, but I can't find the setting. Can anyone tell me how to enable it after the project has been created?

    When I attempt to connect to SQL server using enterprise manager I get the strange message: "SQL Server is not known to be running. Are you sure you want to connect?" What is it trying to tell me? Is there some special caution required in trying to connect to a server that is not known to be running?
