【问题描述】：
我创建了一个希望转发到的对话框
using Microsoft.Bot.Builder.Dialogs;
using pc.apm.bot.Services;
using System;
using System.Diagnostics;
using System.Threading.Tasks;
namespace pc.apm.bot.Dialogs
{
[Serializable]
public class NewUserDialog : IDialog<string>
{
IApmService _apmService;
LangaugeCodes _langaugeCode;
public NewUserDialog(IApmService apmService, LangaugeCodes langaugeCode)
{
_apmService = apmService;
_langaugeCode = langaugeCode;
}
public async Task StartAsync(IDialogContext context)
{
if (new TraceSwitch("apmDiagnostics", "").Level == TraceLevel.Info)
await context.PostAsync($"Current Dialog: {this.GetType().Name}");
context.Wait<string>(MessageReceivedAsync);
}
private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<string> result)
{
var userEmail = await result;
await context.PostAsync(StringResourceService.GetStringResource(StringKeys.NewUserStarted_Key, _langaugeCode));
var apmId = await _apmService.CreateUserAsync(userEmail.ToLower());
var UserProvisionedAlfabet_Text = StringResourceService.GetStringResource(StringKeys.UserProvisionedAlfabet_Key, _langaugeCode);
await context.PostAsync(String.Format(UserProvisionedAlfabet_Text, userEmail));
context.Done(apmId);
}
}
}
现在它的工作方式是在上一个对话框中，我有一些逻辑决定需要配置新用户，在这种情况下，它会将用户电子邮件转发到 NewUserDialog 以执行此操作。
await context.Forward(
child: new NewUserDialog(),
resume: (c, r) => AddProfile(context, result),
item: user.Email,
token: CancellationToken.None);
所以一切正常，花花公子，我遇到的问题是对这段代码进行单元测试；我正在尝试遵循 bot builder 测试项目中的规定
https://github.com/Microsoft/BotBuilder/tree/master/CSharp/Tests/Microsoft.Bot.Sample.Tests
现在我的测试开始了，只是当我的 NewUserDialog 尝试等待电子邮件地址时，事情失败并引发异常
pc.apm.bot.tests.Test_New_User_Dialog.Create_New_User 抛出异常： Microsoft.Bot.Builder.Internals.Fibers.InvalidTypeException：无效类型：预期 System.String，有 Activity
所以我看到这是一个类型问题；但我不知道如何通过测试代码将电子邮件地址传递给对话框。
这是我的测试代码
using Autofac;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Dialogs.Internals;
using Microsoft.Bot.Builder.Tests;
using Microsoft.Bot.Connector;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Moq;
using pc.apm.bot.Dialogs;
using pc.apm.bot.Services;
using System;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;
namespace pc.apm.bot.tests
{
[TestClass]
public class Test_New_User_Dialog : DialogTestBase
{
[TestMethod]
public async Task Test_method() => Assert.IsTrue(await Task.FromResult(true));
[TestMethod]
public async Task Create_New_User()
{
var mockApmService = new Mock<IApmService>(MockBehavior.Strict);
mockApmService
.Setup(m => m.CreateUserAsync(It.IsAny<string>()))
.Returns<string>(x => Task.FromResult("123-123"));
var NewUserDialog = new NewUserDialog(mockApmService.Object, LangaugeCodes.en_US);
var toBot = DialogTestBase.MakeTestMessage();
toBot.From.Id = Guid.NewGuid().ToString();
Func<IDialog<string>> MakeRoot = () => NewUserDialog;
using (new FiberTestBase.ResolveMoqAssembly(NewUserDialog))
using (var container = Build(Options.MockConnectorFactory | Options.ScopedQueue, NewUserDialog))
{
using (var scope = DialogModule.BeginLifetimeScope(container, toBot))
{
DialogModule_MakeRoot.Register(scope, MakeRoot);
await Conversation.SendAsync(scope, toBot);
var firstResponse = scope.Resolve<Queue<IMessageActivity>>().Dequeue();
Assert.IsTrue(firstResponse.Text.Equals("Looks as if you are a new user, let's get you started!"));
var secondResponse = scope.Resolve<Queue<IMessageActivity>>().Dequeue();
Assert.IsTrue(secondResponse.Text.Equals("A user for pawel.chooch@fake.com has been provisioned in System"));
}
}
}
}
}
所以简而言之，我的问题是如何通过将参数从父对话框转发给它来测试接收参数的对话框？
