Unit tests using NUnit & Devart's LINQ to SQL ?

Hiya, I'm currently having some fun with one of the trials for MySQL's dotConnect versions.

[C#]
I've created an assembly which is supposed to perform IO operations on an MySQL database using devart's linq to sql model, and a separate assembly to host unit tests using NUnit.

I've referenced assembly #1 in NUnit's assembly, created some basic tests for IO operations - and got a lot of failures. apparently there's an exception being thrown saying :

"Connection string \"DataContextConnectionString\" could not be found in the configuration file."

I'd apreciate some advice how to solve this, as this is getting increasingly frustrating.

.NET use the configurations file for the "main" assembly, in this case your test project. That config doesn't contain your connectionstring.

Hello, misztalm. Please let us know if the suggestion by JonasJ was helpful.

Heya, yes it was - to some extent.

Here's a complete solution :

Create a new dll library project containing the NUnit tests.
Add the app.config file from the assembly containing Devart's dlls (the connection string needs to be present in the NUnit assembly)
In the NUnit application, edit the project's settings and have the project explicitely use the app.config file as the project's configuration.
