带有 ASP.NET 网站的 NUnit

Question

我目前正在尝试升级我们工作中的构建服务器，从没有构建服务器到拥有一个！

我正在使用 JetBrains 的 TeamCity （已使用 ReSharper 几年了，我信任他们的东西），并打算使用 NUnit 和 MSBuild。

但是，我遇到了一个问题：似乎无法使用 NUnit 测试 ASP.NET 网站。我原以为可以将其配置为在构建后测试 App_Code，但似乎很好地进行测试的唯一方法是将网站转换为 Web 应用程序（我的老板不喜欢这个想法）。

我该怎么办呢？

请记住，测试需要能够从 TeamCity 自动触发。

Answer 1

• 如果您想对您的网站进行冒烟测试，或对某些端点进行攻击 - 请参阅下面的代码。

  如果

• 另一方面，如果您想测试不可测试（可憎）的 ASP.NET 网站程序集（而不是 Web 应用程序），正如法国人所说，SOL

程序集是一个随机命名的动态编译程序集框架临时 ASP.NET 文件的数量，使得测试几乎不可能。

您确实需要考虑几个选项：

1. 将需要测试的逻辑放在单独的程序集中。
2. 更改为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想要的东西，但我可能是错的。让我们来看看。

祝你好运

下载带有站点和应用程序的 Visual Studio 2008 示例。

我为 WebHost.WebServer.dll 编写了一个包装器，它是开发服务器的核心，在 CI。我一直用它。

这是一个缩小版本，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"));
        }
    }
