问题描述
当我为我的插件运行单元测试时，我得到以下异常被抛出:
这是从 CRM Online 中检索到的日志文件！

解决方案
单元测试不是我的强项.但我会尽力指导你.
首先，我对单元测试的看法.我在 Dynamics 中不太重视它，因为它是一个难以控制的环境.您可以测试您的业务逻辑是否在插件中得到了很好的实现，但是 javascript、业务规则、工作流或操作可能会破坏您的逻辑.您的插件可以显示为蓝色，但异步工作流程会立即将其更改为红色.
相反，我更喜欢 UI 测试.它将测试从 A 到 Z 的过程并强制执行上述所有组件.这是我推荐的一个不错的框架:https://github.com/Microsoft/EasyRepro
话虽如此.要解决您的问题，您还需要模拟组织服务并返回假数据.我的意思是这一行:
EntityCollection unitsum_am_result = service.RetrieveMultiple(new FetchExpression(unitsum_am));遗憾的是，即使您模拟，您也无法真正解析 fetchXml 并对其进行验证.
然后，在返回假数据后，您应该断言这一行，创建一个具有正确总和的实体:

Here is the code for Eachday:

namespace DCWIMS.Plugins
{
public class Eachday

public List<string> WeekDay(DateTime from, DateTime thru)
{
List<string> days_list = new List<string>();
for (var day = from.Date; day.Date <= thru.Date; day = day.AddDays(1))
{
days_list.Add(day.ToLongDateString());
if (day.DayOfWeek == DayOfWeek.Sunday || day.DayOfWeek == DayOfWeek.Saturday)
days_list.Remove(day.ToLongDateString());
}
return days_list;
}
}
}
My unit test looks like this:
using DCWIMS.Plugins;
using Microsoft.Crm.Sdk.Fakes;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Microsoft.Xrm.Sdk;
namespace Plugins.Tests
{
[TestClass]
public class UnitTest1
{
[TestMethod]
[TestCategory("Unit Test")]
public void TestUnitPlugin()
{
using (var pipline = new PluginPipeline(FakeMessageNames.Update, FakeStages.PreOperation, new Entity("contract")))
{
var plugin = new UnitPlugin();
pipline.Execute(plugin);
}
}
}
}
Even when I registered the plugin on the actual CRM instance I got this error message:
Here is the log file retrieved from CRM Online!

解决方案
Unit testing ain't my forte. But I will try to guide you.
First, my opinion on unit testing. I don't value it much in Dynamics because it's an environment that is hard to control. You can test that your business logic is well implemented in the plugin but a javascript, a business rule, a workflow or an action can derail your logic. Your plugin can say blue but an async workflow change it to red right after.
Instead, I prefer UI testing. It will test the process from A to Z and force the execution of all the components mentioned above. Here's a nice framework I recommend: https://github.com/Microsoft/EasyRepro
That being said. To solve your problem you also need to mock the Organization Service and return fake data. By that, I mean this line:
EntityCollection unitsum_am_result = service.RetrieveMultiple(new FetchExpression(unitsum_am));
Sadly, even if you mock, you can't really parse the fetchXml and validate it.
Then, after returning the fake data you should assert that this line, create an entity with the right sums:
service.Create(alterunit);
