I've written a web application that uses the M.P.E.D namespace to do
all of its data layer tasks (and a nifty bit of code M.P.E.D is too!).
However, unit-testing is proving a bit of a problem, as the database
factory complains it is unable to locate the expected
dataconfiguration file :

1) MyBusinessObject.Tests.RegistrationFixture.SimpleR egistration :
System.Configuration.ConfigurationException : Invalid section name.
The section 'dataConfiguration' does not exist in the requested
configuration file
'E:\Inetpub\wwwroot\MyApplication\MyBusinessObject .Tests\bin\Debug\MyBusines
sObject.Tests.dll.config'
or the file
'c:\winnt\microsoft.net\framework\v1.1.4322\Config \machine.config'.
Make sure that the 'enterpriseLibrary.configurationSections'
configuration section exists in one of the files and that the section
'dataConfiguration' is defined.

I created an app.config and a dataconfiguration.config in the root
directory of the unit test library, and added a post-build event to
VS.NET to copy the .config files to the bin/debug folder, and indeed
the files get copied there, but the tests are still failing. Any idea
how to unit tests apps written with the EnterpriseLibrary?
