如果您想对您的网站进行烟雾测试，或者测试一些端点 - 请参考下面的代码。
另一方面，如果您想测试ASP.NET网站集成程序集（而不是Web应用程序）的难以测试的部分，正如法国人所说，您是无能为力的。
这个程序集是一个随机命名的动态编译程序集，位于框架临时ASP.NET文件的深处，使得测试接近不可能。
您确实需要考虑几个选项：
- 将需要测试的逻辑放置在单独的程序集中。
- 切换到提供可测试程序集的Web应用程序项目。
抱歉，我认为您不会找到您要寻找的内容，但我可能是错的。 我们来看看吧。
祝好运
下载带有网站和应用程序的Visual Studio 2008示例。
我为WebHost.WebServer.dll编写了一个包装器，这是开发服务器的核心，在CI中运行良好。我经常使用它。
这里有一个缩小版，包括使用示例。
Test.cs
using System.Net;
using NUnit.Framework;
namespace Salient.Excerpts
{
[TestFixture]
public class WebHostServerFixture : WebHostServer
{
[TestFixtureSetUp]
public void TestFixtureSetUp()
{
// debug/bin/testproject/solution/siteundertest - make sense?
StartServer(@"..\..\..\..\TestSite");
// is the equivalent of
// StartServer(@"..\..\..\..\TestSite",
// GetAvailablePort(8000, 10000, IPAddress.Loopback, true), "/", "localhost");
}
[TestFixtureTearDown]
public void TestFixtureTearDown()
{
StopServer();
}
[Test]
public void Test()
{
// while a reference to the web app under test is not necessary,
// if you do add a reference to this test project you may F5 debug your tests.
// if you debug this test you will break in Default.aspx.cs
string html = new WebClient().DownloadString(NormalizeUri("Default.aspx"));
}
}
}

注意：Microsoft.VisualStudio.WebHost命名空间包含在WebDev.WebHost.dll文件中。该文件位于GAC中，但无法从Visual Studio中添加对此程序集的引用。
要添加引用，您需要在文本编辑器中打开.csproj文件并手动添加引用。
查找包含项目引用的ItemGroup并添加以下元素：
<Reference Include="WebDev.WebHost, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=x86">
<Private>False</Private>
</Reference>

这是一个“网站”，而不是应用程序，因此没有.csproj文件！我不太确定你使用Web服务器包装器的目的是什么：我的主要问题是NUnit根本无法从站点内运行测试，它根本不能识别它们！ - Ed James
你想要测试什么？你不能只是在VS中打开网站，然后新建项目>类库，然后将你的测试项目简单地添加到包含你的网站的解决方案中吗？ - autonomatt
@mattRo55 我试过了，但它不允许你在另一个项目中引用网站上的代码。 - Ed James
很棒。我实际上已经成功让它工作了（ReSharper让你可以做到，不知道是否有办法通过NUnit GUI或命令行来实现）。 - Ed James
@Ed- Resharper深入VS，因此它知道从哪里获取程序集并将其复制到其影子缓存中。其他工具则不然，特别是CI工具如TeamCity。 - Sky Sanders
