Errors running Integration Tests with RavenDB Embedded

[Kent Cooper]

I just updated to vs2017 and the latest version of Raven 3.5(v3.5.30) so I'm not sure which one caused this problem but now when I try to run my tests they fail with the following error

Message: Assembly Initialization method Api.Tests.TestHost.Setup threw exception. System.TypeLoadException: System.TypeLoadException: Could not load type 'Jint.Native.JsValue' from assembly 'Raven.Database, Version=3.5.3.0, Culture=neutral, PublicKeyToken=37f41c7f99471593' due to value type mismatch.. Aborting test execution.

 Stack trace of the error:

Here's the code I use to configure the database:

public class EmbeddedRavenDatabase : IRavenDatabase
   {
       private static bool _configured = false;
 
       public IDocumentStore Store
       {
           get
           {
               return _lazyDocStore.Value;
           }
       }
 
       private static readonly Lazy<IDocumentStore> _lazyDocStore = new Lazy<IDocumentStore>(() =>
                                                                       {
                                                                           var docStore = new EmbeddableDocumentStore
                                                                           {
                                                                               RunInMemory = true,
                                                                           };
                                                                           docStore.Configuration.Storage.Voron
                                                                               .AllowOn32Bits = true;
                                                                           docStore.RegisterListener(new NoStaleQueriesAllowed());
                                                                           docStore.Initialize();
 
                                                                           if (!_configured)
                                                                           {
                                                                               var complete = CreateIndexes(docStore).Result;
                                                                           }
 
                                                                           return docStore;
                                                                       });
 
       private static async Task<bool> CreateIndexes(IDocumentStore docStore)
       {
           CreateApiClients.AddTestClient = true;
           var indexTask = IndexCreation.CreateIndexesAsync(typeof(RavenDatabase).Assembly, docStore);
           var seedTask = CreateApiClients.Seed(docStore);
           var appTask = CreateApplication.Seed(docStore);
           var timezoneTask = CreateTimeZones.Seed(docStore);
 
           await Task.WhenAll(indexTask, seedTask, appTask, timezoneTask);
 
 
           LogManager.RegisterTarget<RavenDebugTarget>();
           _configured = true;
 
           return true;
       }
   }

Any help figuring out this error would be appreciated. Also not sure if it matters but the project that is being tested also has a reference to jint(vs2.10)

Thanks,

Kent

Hi Kent,

RavenDB embedds it's own version of Jint so the version that you are using conflicts the one that is used internally. If possible please reference https://github.com/ravendb/ravendb/blob/v3.5/SharedLibs/Jint.dll (this is 2.8 with one minor feature added: ability to turn on NullPropagation which is turned off by default IIRC).

With regards,

P.
