如何在仍然引用NUnit的同时使我的visual studio 2017项目不是测试项目

Question

我有一个带有unittest辅助类的库。我在这个项目中引用了NUnit，但现在Visual Studio认为这个项目是一个测试项目并且抱怨没有发现测试。这个项目并不是一个测试项目，只是一个引用NUnit的常规.net标准库。

我想“说服”视觉工作室，这不是一个测试项目。有任何想法吗？

技术细节：该项目是一个.Net Standard 2.0项目，我引用了以下NuGet包：

• 我的h.10.0
• Моя.Автотомок1.2.0.111
• NUnit 3.10.1

我使用Visual Studio 2017企业版15.8.4

此库的用途示例：

  public abstract class AutoMockerTestBase
  {
     protected AutoMocker AutoMocker { get; private set; }

     [SetUp]
     public virtual void SetUp()
     {
        AutoMocker = new AutoMocker(MockBehavior.Strict);
     }

     [TearDown]
     public virtual void TearDown()
     {
        AutoMocker.VerifyAll();
     }
  }

重现问题：

• 将.net standard2.0类库项目添加到解决方案中。
• 参考NUnit

现在请注意，visual studio将项目图标更改为测试项目。

帮我找到一种方法让视觉工作室不要认为这个项目是一个测试项目，并确保vs不会尝试在这个项目中发现测试。

编辑：通过“测试”输出我发现：

Answer 1

如果你在汇编级别应用NonTestAssemblyAttribute，那将告诉NUnit它不是一个测试程序集。但是，您必须查看在Visual Studio下运行时是否可以防止该错误。
