How to unit test a single conversational statement - unit-testing

Question

i am working with bots and the Microsoft Bot Framework.
I used the DispatchBot template to generate my bot. (https://learn.microsoft.com/de-de/azure/bot-service/bot-builder-tutorial-dispatch?view=azure-bot-service-4.0&tabs=cs)
For conversational testing, i want to create unit tests. Therefore i used this documentation to gather some informations (https://learn.microsoft.com/de-de/azure/bot-service/unit-test-bots?view=azure-bot-service-4.0&tabs=csharp)
The thing is that i dont want to test dialogs, but a single statement (a question and the right answer)
How can i implement this?
Here you can see the Start of my Dispatchbot.cs file where the magic happens (search of the correct Knowledge Base etc.)

Here's a link to how we create tests for CoreBot. The part you're most likely interested in is testing things under the /Bots directory. Based off of the test code you can find there, you likely want something like:
using System;
using System.Threading;
using System.Threading.Tasks;
using CoreBot.Tests.Common;
using Microsoft.Bot.Builder;
using Microsoft.Bot.Builder.Adapters;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.BotBuilderSamples.Bots;
using Microsoft.Extensions.Logging;
using Moq;
using Xunit;
namespace KJCBOT_Tests
{
public class BotTests
{
[Fact]
public async Task TestResponseToQuesion()
{
// Note: this test requires that SaveChangesAsync is made virtual in order to be able to create a mock.
var memoryStorage = new MemoryStorage();
var mockConversationState = new Mock<ConversationState>(memoryStorage)
{
CallBase = true,
};
var mockUserState = new Mock<UserState>(memoryStorage)
{
CallBase = true,
};
// You need to mock a dialog because most bots require a Dialog to instantiate it.
// If yours doesn't you can likely skip this
var mockRootDialog = SimpleMockFactory.CreateMockDialog<Dialog>(null, "mockRootDialog");
var mockLogger = new Mock<ILogger<DispatchBot<Dialog>>>();
// Act
var sut = new DispatchBot<Dialog>(mockConversationState.Object, mockUserState.Object, mockRootDialog.Object, mockLogger.Object);
var testAdapter = new TestAdapter();
var testFlow = new TestFlow(testAdapter, sut);
await testFlow
.Send("<Whatever you want to send>")
.AssertReply("<Whatever you expect the reply to be")
.StartTestAsync();
}
}
}
