Testing a method using nunit that requires configuration from ConfigurationManager

Question

I am trying to run a NUnit test for a method that gets a connection string from a web.config file. When I test it, it clearly crashes when trying to pull this connection string. So I poked and came to this URL:

Test module for app.config using NUnit

Here is the user code:

void BasicSetup()
{
     ConnectionStringSettings connectionStringSettings = new ConnectionStringSettings();
     connectionStringSettings.Name = "testmasterconnection";
     connectionStringSettings.ConnectionString = "server=localhost;user=some;database=some;port=3306;";
     ConfigurationManager.ConnectionStrings.Clear();
     ConfigurationManager.ConnectionStrings.Add(connectionStringSettings);
}

It almost seemed like the answer I was looking for. When I actually paste the code, I get the following error: Failure: System.Configuration.ConfigurationErrorsException: read-only configuration.

Is there anything else I should do first? Thank!

Configuration config = ConfigurationManager.OpenExeConfiguration("test.exe");
