NServiceBus Test.Initialize() given key was not present

Question

Update just read the Google group in more detail and apparently it's a app config issue. Will update post after trying.

I was wondering if anyone knows of this issue when attempting to unit test NServiceBus.

Realise I have two initialize methods below but this is to illustrate what I am trying to do. Stack trace based on request.

(NServiceBus.LocalAddress) was not present in the dictionary. (NServiceBus.LocalAddress) was not present in the dictionary.

Other part of the stack trace I believe is a red herring complaining about InMemoryPersistence. However, there is a Google group talking about this issue too who experienced the same issue which makes me think it's more of an NServiceBus issue rather than a coding mistake.

Should mention seen these posts.

public static class CustomInit
    {
        public static void Init()
        {
            //Previous versions of NBUS, specifically 4.6.5
            //MessageConventionExtensions.IsEventTypeAction = MessageConfiguration.ForEvents();
            //MessageConventionExtensions.IsCommandTypeAction = MessageConfiguration.ForCommands();            

            //New 5.2.0 how to setup tests
            Test.Initialize(x => x.AssembliesToScan(GetAssembliesToScan()));

            Test.Initialize(
                x =>
                {
                    x.Conventions().DefiningCommandsAs([my namespace]);
                    x.Conventions().DefiningEventsAs([my namespace]);
                    x.AssembliesToScan(GetAssembliesToScan());
                });
        }

        private static IEnumerable<Assembly> GetAssembliesToScan()
        {
            return new[]
            {
                AssemblyFromType<ISomeInterface>()
            };
        }
}

After raising the issue on GitHub found that need to include NServiceBus.Testing as part of the assembly scanning. For example:

Should point out also, for further information I would visit the GitHub link. Further detail about the issue and an explanation can be found there.

    public static void Init()
    {
        Test.Initialize(
            x =>
            {
                x.Conventions().DefiningCommandsAs(x => x.Namespace.Contains("Commands"));
                x.Conventions().DefiningEventsAs(x => x.Namespace.Contains("Events"));
                x.AssembliesToScan(GetAssembliesToScan());
            });
    }

    private static IEnumerable<Assembly> GetAssembliesToScan()
    {
        return new[]
        {
            AssemblyFromType<ISomeInterface>(),
            Assembly.LoadFrom("NServiceBus.Testing.dll")
        };
    }

The key point being this Assembly.LoadFrom("NServiceBus.Testing.dll")
