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")

Cheers, DS.

In my case, the tests were failing with this error message in NCrunch.

That's probably because NCrunch was running the tests from the following location:

C:\Users\[username]\AppData\Local\NCrunch\...

The solution was to go to:

NCrunch -> Configuration

Select the project affected and set the flag 'Copy referenced assemblies to workspace' to True.
