Question

Hi I am having a problem with NUnit and ConfigurationManager

I have several unti tests to test manipulation of a configuration file. in most of my tests I create a file and delete it at the end of the test.

However I have 2 tests where I create the file using new ConfigurationManager(path);
I then attempt to re-open the same file with the same path again using new ConfigurationManager(path);

I create an NUnit project and run it along with a few other nunit tests.

Recently we were forced to fix our platform to x86 (due to 3rd party components)

Prior to this change everything worked fine but now I constantly get an exception during the above mentioned tests and specifically on the line new ConfigurationManager(path);
The exception is IO.FileNotFoundException and refering to one of my application libraries.

Also to confuse me even more, the exception only occurs when I run the test via the project. It does not occur when I run the test using visual studios or when I add the dll directly to the nunit client (drag and drop)

Thanks in advance for any help

-EDIT:
I have added the exceptions and the config file xml for reference

Hornbill.UnitTests.Configuration.ConfigurationManagerBasics.TestAppendGetDelete:

So I solved the problem by changing the NUnit setting: Test Loader – Default Process Model to “Run tests in a separate process per Assembly”
