C# VisualStudio NUnit3TestAdapter与第三方DLL的测试项目

我有一个测试项目

Proj_Test

，有两个nuget包

<packages>
  <package id="NUnit" version="3.6.0" targetFramework="net45" />
  <package id="NUnit3TestAdapter" version="3.6.0" targetFramework="net45" />
</packages>

设置似乎被忽略

如何管理测试的这些依赖关系

编辑： 我想我是怎么了

专用程序集部署在与应用程序相同的目录结构中。如果为PrivateBinPath指定的目录不在ApplicationBase下，则将忽略它们

创建副本真的是唯一的解决方案吗？

如果找不到更好的解决方案，请尝试自己解决

using ConsoleApplication6;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System;
using System.Reflection;

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [TestInitialize]
        public void Init()
        {
           AppDomain currentDomain = AppDomain.CurrentDomain;
           currentDomain.AssemblyResolve += MyResolveEventHandler;
        }

        [TestMethod]
        public void TestMethod1() { Assert.AreEqual(new MyClass().DoSomething(), 1); }

        [TestMethod]
        public void TestMethod2() { Assert.AreEqual(new MyClass().DoSomething(), 1); }

        private Assembly MyResolveEventHandler(object sender, ResolveEventArgs args)
        {
            return Assembly.LoadFile(@"C:\MyPath\MyAssembly.dll");
        }
    }
}

不幸的是，程序集探测只能在子目录上工作，所以您不能使用它…

多亏了George Vos的回答，这就是我最终实现的

我查看了“AssemblyResolve”，似乎您需要按方法分离调用。因此，我在“OneTimeSetUp”中尝试了它，但没有触发事件-我可能遗漏了什么？@Johannes我想不出原因。我回家后会尝试。我认为我的依赖项之一是本机dll。这可能与此有关。@Johannes我看不出TestInitialize有问题……请尝试在MyResolveEventHandler中添加断点和Try/catch，并检查未能加载的程序集（请参见args.Name）还有whyok-在我的最小示例中，我注意到a）您的代码适用于托管程序集，b）我需要为本机DLL设置路径。使用函数AddDllDirectories并不简单，因此为了兼容性，我使用SetDllDirectories。
