I am using VS 2015 Update 2 with Resharper Ultimate 2016.1 and I have this weird issue.

I have a test project called Test which references two projects, Model and Persistence. The model project contains nhibernate entity classes and the Persistence project contains *.hbm.xml files. They were generated with llblgenpro 4.2. I am using nhibernate 4.0.4.

I initialize NHibernate with this call:

  NHibernateSession.Init(
    new SimpleSessionStorage(), 
    new string[] { "Persistence.dll", "Model.dll" });

When I run one of my test cases the nhibernate initialization fails with this exception:

System.IO.FileNotFoundException was unhandled by user code

  InnerException:

If I copy the persistence.dll to the C:\Users\costa\AppData\Local\JetBrains\Installations\ReSharperPlatformVs14 folder, the test case works fine. persistence.dll is in the C:/projects/csharp/Test/bin/Debug folder because the persistence project is referenced in the test project.

This all worked fine in VS 2013 with nhibernate 3.3.1. Also I got all the dll versions to align using the assemblybinding elements in the test project app.config file.

My projects target .Net 4.6 and I use nunit 3.2.1.

I found this:

Resharper runs UnitTest from different location

However, in my case 'Shadow-copy assemblies being tested' is turned off, Use separate AppDomain for each assembly with tests is also turned off. Run Tests from is set to Project output folder.

Any ideas what could cause this?

Thanks

An update: If I do this it works:

  string path = Assembly.GetExecutingAssembly().Location;
  string directory = Path.GetDirectoryName(path);

  NHibernateSession.Init(
    new SimpleSessionStorage(), 
    new string[] { directory + "\\Persistence.dll", directory + "\\Model.dll" });

Update 2. My project uses the Sharp Architecture library. NHibernateSession is a class that belongs to this library.

  • What is `NHibernateSession`? It does not look to me as a native part of NHibernate. If this is some custom class, it is hard to help you without having its code. Maybe that is some class generated by llblgenpro: it could be better to ask them for their support in such case. – Frédéric Apr 26 '16 at 12:21
  • And maybe you would have it easier to leave aside llblgenpro and works directly with your mappings and session factory. It would allow you to fine tune them to your business needs. (You may read more about my view [here](/a/35589532/1178314).) And you would have more option for handling your session factory initialization, such as the one in my answer [here](/a/35711701/1178314). – Frédéric Apr 26 '16 at 12:29
  • @Frédéric: I updated my post. That NHibernateSession belongs to the s#arp-architecture library. Sorry, I missed this. – boggy Apr 26 '16 at 16:13

This is likely a change in NUnit 3, which no longer changes the current directory to the location of the assembly under test. I believe this is because it can run multiple assemblies in a single test run - so which directory would be best?

As per the NUnit 3 Breaking Changes document, you can use TestContext.CurrentContext.TestDirectory to locate the directory that contains the assembly under test.
