Microsoft Bot Framework - Unit Test Fail

Question

I'm currently attempting to write unit tests for my bot, however, the test always fail when attempting to get a response. I've created a mock test which inherits DialogTestBase.

[TestClass]
public class Tests : DialogTestBase
{
    [TestMethod]
    public async Task TestDialogTest()
    {
        await TestDialogFlow(new TestDialog());
    }

    private async Task TestDialogFlow(IDialog<object> echoDialog)
    {
        // arrange
        var toBot = DialogTestBase.MakeTestMessage();
        toBot.From.Id = Guid.NewGuid().ToString();
        toBot.Text = "Hi";

        Func<IDialog<object>> MakeRoot = () => echoDialog;

        using (new FiberTestBase.ResolveMoqAssembly(echoDialog))
        using (var container = Build(Options.MockConnectorFactory | Options.ScopedQueue, echoDialog))
        {
            IMessageActivity toUser = await GetResponse(container, MakeRoot, toBot);

            Assert.IsTrue(toUser.Text.StartsWith("Hello"));
        }
    }

    private async Task<IMessageActivity> GetResponse(IContainer container, Func<IDialog<object>> makeRoot, IMessageActivity toBot)
    {
        using (var scope = DialogModule.BeginLifetimeScope(container, toBot))
        {
            DialogModule_MakeRoot.Register(scope, makeRoot);

            // act: sending the message
            await Conversation.SendAsync(toBot, makeRoot);
            return scope.Resolve<Queue<IMessageActivity>>().Dequeue();
        }
    }
}

The dialog i'm testing is:

[Serializable]
public class TestDialog : IDialog
{
    public async Task StartAsync(IDialogContext context)
    {
        context.Wait(ProcessMessage);
    }

    public async Task ProcessMessage(IDialogContext context, IAwaitable<IMessageActivity> argument)
    {
        await context.PostAsync("Hello. I'm a bot");
        await context.PostAsync("How can I help?");

        context.Wait(ProcessRequest);
    }

    public async Task ProcessRequest(IDialogContext context, IAwaitable<IMessageActivity> argument)
    {
        var request = await argument;

        await context.PostAsync($"You asked the following question: {request}");

        context.Done(true);
    }
}

When I run the test I get the following error:

Autofac.Core.DependencyResolutionException: An exception was thrown while executing a resolve operation. See the InnerException for details. ---> Invalid URI: The format of the URI could not be determined. (See inner exception for details.) --->System.UriFormatException: Invalid URI: The format of the URI could not be determined.

The problem happens in the GetResponse method when we send the request. Any help would be greatly appreciated.

The GetResponse method should actually call SendAsync using scope and toBot as parameters:

await Conversation.SendAsync(toBot, makeRoot);

I tried the code you've shared and after making this change, the test passes.
