问题描述
我们试图对存储在某个字典中的每个案例进行单元测试，当用户发送字符串并且测试必须用字符串回答时，它似乎工作正常。但是我们找不到任何关于如何测试其他类型对话框的文档，例如附件、按钮等。
我们希望制作一个字符串、对象的字典，其中字符串是我们向机器人询问的内容，而对象是字符串、附件、对话框。
代码示例
这是我们存储答案的方式:
public static Dictionary<string, object> data = new Dictionary<string, object>{
{"Nuevo", "Que quieres crear?"},
{"Ayuda", "Ya te ayudas!"},
{"Adios", "Nos vemos!"},
{
"Coche",
new Attachment() {
ContentUrl = "https://media.ed.edmunds-media.com/subaru/impreza/2006/oem/2006_subaru_impreza_sedan_sti_fq_oem_1_500.jpg",
ContentType = "image/png",
Name = "Subaru_Impreza.png"
}
},
{
"Moto",
new Attachment() {
ContentUrl = "http://motos.honda.com.co/sites/default/files/motos/cb-1000-r-cc-menu-honda.png",
ContentType = "image/png",
Name = "moto.png"
}
},
{
"Perro",
new Attachment() {
ContentUrl = "https://upload.wikimedia.org/wikipedia/commons/thumb/6/6b/Taka_Shiba.jpg/1200px-Taka_Shiba.jpg",
ContentType = "image/png",
Name = "ShibaInu.png"
}
}
};
这就是机器人的工作原理和返回所有内容的方式，这至少对文本和附件是按预期工作的，但我们还没有对更多类型的消息这样做。
private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
var activity = await result as Activity;
var r = context.MakeMessage();
foreach (var item in data)
{
if (item.Key == activity.Text)
{
if (item.Value is Attachment)
{
r.Attachments = new List<Attachment>() { item.Value as Attachment };
}
if (item.Value is string)
{
r.Text = item.Value.ToString();
}
break;
}
}
// return our reply to the user
await context.PostAsync(r);
context.Wait(MessageReceivedAsync);
}
但是当我们要对其进行测试时，它只有在我们发送的是字符串而不是在模拟器中工作的 IMessageActivity 时才有效。
测试代码:
[TestMethod]
public async Task Pregunta_respuesta_prueba()
{
foreach (var item in RootDialog.data)
{
var preg = item.Key;
var resp = item.Value;
if (item.Value is Attachment)
{
Attachment auxText = resp as Attachment;
resp = auxText.ContentUrl;
}
using (ShimsContext.Create())
{
// Arrange
var waitCalled = false;
object message = null;
var target = new RootDialog();
var activity = new Activity(ActivityTypes.Message)
{
Text = preg
};
var awaiter = new Microsoft.Bot.Builder.Internals.Fibers.Fakes.StubIAwaiter<IMessageActivity>()
{
IsCompletedGet = () => true,
GetResult = () => activity
};
var awaitable = new Microsoft.Bot.Builder.Dialogs.Fakes.StubIAwaitable<IMessageActivity>()
{
GetAwaiter = () => awaiter
};
var context = new Microsoft.Bot.Builder.Dialogs.Fakes.StubIDialogContext();
Microsoft.Bot.Builder.Dialogs.Fakes.ShimExtensions.PostAsyncIBotToUserStringStringCancellationToken = (user, s1, s2, token) =>
{
message = s1;
Console.WriteLine(message);
return Task.CompletedTask;
};
Microsoft.Bot.Builder.Dialogs.Fakes.ShimExtensions.WaitIDialogStackResumeAfterOfIMessageActivity = (stack, callback) =>
{
if (waitCalled) return;
waitCalled = true;
// The callback is what is being tested.
callback(context, awaitable);
};
// Act
await target.StartAsync(context);
// Assert
Assert.AreEqual(resp, message);
}
}
}
如果你检查这部分代码
Microsoft.Bot.Builder.Dialogs.Fakes.ShimExtensions.PostAsyncIBotToUserStringStringCancellationToken = (user, s1, s2, token) =>
{
message = s1;
Console.WriteLine(message);
return Task.CompletedTask;
};
```
它仅在机器人返回字符串时有效，我们甚至无法检查它是否是一个事件，发生这种情况是因为我们为测试创建的假上下文没有按预期工作。
我们伪造的 IDialogContext 在它是一个对象时似乎根本不起作用，但在它是一个字符串时它确实起作用。
private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
var activity = await result as Activity;
/// Here when the test is running, this context.MakeMessage is null, but when the bot
/// is working, it wors perfectly.
var r = context.MakeMessage();
foreach (var item in data)
{
if (item.Key == activity.Text)
{
if (item.Value is Attachment)
{
r.Attachments = new List<Attachment>() { item.Value as Attachment };
}
if (item.Value is string)
{
r.Text = item.Value.ToString();
}
break;
}
}
// return our reply to the user
await context.PostAsync(r);
context.Wait(MessageReceivedAsync);
}
复制步骤
要尝试这一点，您可以尝试使用附件进行测试，代码在 this 中。存储库。
最佳答案
除了使用 PostAsyncIBotToUserStringStringCancellationToken，您还可以使用 context.PostAsyncIMessageActivityCancellationToken 并且，在 RootDialog 的 MessageReceivedWithTextAsync 中使用事件回复而不只是字符串进行响应。
public async Task MessageReceivedWithTextAsync(IDialogContext context, IAwaitable<object> result)
{
var activity = await result as Activity;
string r = "";
foreach (var item in dataText)
{
if (item.Key == activity.Text)
{
r = item.Value;
break;
}
}
var reply = activity.CreateReply(r);
foreach (var item in dataAtt)
{
if (item.Key == activity.Text)
{
reply.Attachments.Add(item.Value);
reply.Text = "attachment";
break;
}
}
if ((string.IsNullOrWhiteSpace(r) || r == null) && reply.Attachments.Count == 0)
{
reply.Text = "No tengo respuesta para eso.";
}
// return our reply to the user
await context.PostAsync(reply);
}
以下是对测试方法的更改:
[TestMethod]
public async Task Bot_Test_Attachments()
{
foreach (var item in RootDialog.dataAtt)
{
var preg = item.Key;
var att = item.Value;
using (ShimsContext.Create())
{
var waitCalled = false;
IMessageActivity message = null;
var target = new RootDialog();
var activity = new Activity(ActivityTypes.Message)
{
Text = preg,
From = new ChannelAccount("id","name"),
Recipient = new ChannelAccount("recipid","recipname"),
Conversation = new ConversationAccount(false,"id","name")
};
var awaiter = new Microsoft.Bot.Builder.Internals.Fibers.Fakes.StubIAwaiter<IMessageActivity>()
{
IsCompletedGet = () => true,
GetResult = () => activity
};
var awaitable = new Microsoft.Bot.Builder.Dialogs.Fakes.StubIAwaitable<IMessageActivity>()
{
GetAwaiter = () => awaiter
};
var context = new Microsoft.Bot.Builder.Dialogs.Fakes.StubIDialogContext();
context.PostAsyncIMessageActivityCancellationToken = (messageActivity, token) => {
message = messageActivity;
return Task.CompletedTask;
};
Microsoft.Bot.Builder.Dialogs.Fakes.ShimExtensions.WaitIDialogStackResumeAfterOfIMessageActivity = (stack, callback) =>
{
if (waitCalled) return;
waitCalled = true;
callback(context, awaitable);
};
await target.MessageReceivedWithTextAsync(context, awaitable);
Assert.AreEqual(att, message.Attachments[0]);
}
}
}
