Problem with SQLite related nUnit-tests after upgrade to VS2010 and Re#5

Question

After converting to Visual Studio 2010 with ReSharper5 some of my unit tests started failing. More specifically this applies to all unit tests that use NHibernate with SQLit

Answer 1

I got the same error, I was sure that it was due to .NET 4.0 and VS 2010, but when I upgraded to Resharper 5 at work (on VS 2008), I got the same error.

I think this is caused by Resharper 5 test runner. When I used TestDriven.NET they all ran successfully.

I hope JetBrains will release a fix soon. According to what I saw on the forums, they are aware of the problem, so it should not take too long to have a fix.

While this is fixed, I will use TestDriven.NET to run my tests. But I will miss the great Resharper UI ;)

Answer 2

Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4

Solution:

testsettings: choose hosts choose run tests in 64 bit process on 64 bit machine

hoping I could help.

merry coding

Answer 3

There seems to be a mixup between 64bit and 32bit dlls somehow. Switching to use the x64 variant of SQLite.dll fixes the problem. I'm not sure why VS2008 doesn't give this problem though.

Answer 4

Did you look at your compile settings in Visual Studio 2010?

For hiding their inability to get their newest debugger running in 64bit Microsoft decided to switch the default compilation for .Net applications from ANY_CPU to 32bit x86.

That could create your problems.
