[Mono-dev] MySQL Connector - Location Issue

Tue Aug 26 08:55:17 EDT 2008

First off I have scoured the list and found similar but not identical
problems to mine without a solution. Development environemnt is Ubuntu 8.04,
Mono 1.9.1 and Monodevelop 2.0 Alpha.

I have used JUnit for years and I am new NUnit and the nuances of assemblies
and how they are located and loaded.  I have an ASP.NET application that
uses a custom membership provider (w/MySQL as the backend).  The provider
works fine,  everything is being updated and what not.  I added the
following to my web.config to get my MySQL connection working:

      <clear />
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient"
           description=".Net Framework Data Provider for MySQL"
           type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data,
               Version=, Culture=neutral,
PublicKeyToken=c5687fc88969c44d" />

This is great and the ASP.NET app works with MySQL, now the problem.  Being
a good developer, I want to create some unit tests for my membership
provider.  I created a separate test project from my memberhip library
project.  I added a project reference to the membership project in my test
project (good, the dll will get copied to the test project).

In the test project I created an app.config with the above section from my
web.config so my NUnit test will know about the MySQL provider.  I create a
simple test and my membership dll (not the NUnit dll) throws:

Failed to find or load the registered .Net Framework Data Provider
'MySql.Data.MySqlClient'. () ()

My NUnit project copies the app.config to the appropriate output directory
properly named <assembly-name>.dll.config.  Examining the build output
directory shows the NUnit dll and its corresponding config file.  I added a
bit of code to the nunit test and found it is not picking up the correct
config file for the test dll. (it was picking up another config *md*.config,
monodevelop maybe?) I thought the default behavior for NUnit was to pick up
the config if I configured the build directory with the renamed dll.

I tried to open the dll.confg in the unit test directly (I think that just
lets me query the values, it doesn't actually load the provider reference,
if I am wrong here, please advise).

Long winded, but here is the question:  What is the proper way to configure
a unit test to use an app.config so I can specify a provider factory not in
the machine.config?  Or should I just add the factory to machine.config? 
Anyway it is strange that the ASP.NET app works, but the test fails (wrong
configuration being picked up) on the same machine.

Any and all help would be appreciated, I have been googling this issue for a
whole day without a decent solution.
