Running NUnit through Resharper 8 tests fail when crossing between projects due to AppDomain

Question

I recently updated to Resharper 8, and when I tried to run a suite of projects. These tests contain two suites of integration tests that both use IISExpress to run a website

Answer 1

This has now been fixed in Resharper 8.0.2: http://youtrack.jetbrains.com/issue/RSRP-374143#comment=27-572929

Do not forget to tick new option ReSharper | Options | Tools | Unit Testing | "Use separate AppDomain for each assembly with test" to get it works.

i.e. There is now a new option in the Unit Testing settings.

Answer 2

The Workaround:

Have you tried in Visual Studio going to ReSharper -> Options -> Tools -> Unit Testing

Change the setting "Run up to 1 assemblies in parallel" to a higher number. I tried one for each test project. Max is number of cores, I think.

Counterintuitive I know, but it worked for me and I am using AppDomain.CurrentDomain.BaseDirectory in the failing tests

The Cause A caching optimization bug in ReSharper 8. Working Directory is not set properly. Perhaps running in parallel creates a separate process for each test, so they don't trip over each other's settings.

The Fix JetBrains claim that this will be fixed in version 8.0.1

Update: There is a new unit testing option added in Resharper 8.1 to accomodate this scenario. Find it at ReSharper -> Options -> Tools -> Unit Testing -> "Use Separate AppDomain for each assembly with tests.

We see the same issue. I think it's a bug. See: http://youtrack.jetbrains.com/issue/RSRP-380761
