C# 如何使visual studio 2017项目在仍然引用NUnit的情况下不成为测试项目

我有一个带有unittest助手类的库。我在这个项目中引用了NUnit，但现在VisualStudio认为这个项目是一个测试项目，并抱怨没有发现任何测试。此项目不是一个测试项目，只是一个引用NUnit的常规.net标准库

我想“说服”VisualStudio，这不是一个测试项目。 有什么想法吗

技术细节：该项目是一个.Net标准2.0项目，我参考了以下NuGet软件包：

• 最小起订量4.10.0
• Moq.AutoMock 1.2.0.111
• NUnit 3.10.1

我使用Visual Studio 2017企业版15.8.4

此库的用途示例如下：

  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();
     }
  }

要重现问题，请执行以下操作：

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

现在请注意，VisualStudio将项目图标更改为测试项目

请帮助我找到一种方法，使visual studio不认为此项目是测试项目，并确保vs不会尝试发现此项目中的测试

编辑：通过查看“测试”输出，我发现：

如果在程序集级别应用

NonTestAssemblyAttribute

，这将告诉NUnit它不是测试程序集。但是，在Visual Studio下运行时，您必须查看这是否可以防止出现错误。

在.csproj文件中，您应该能够添加以下内容：

<PropertyGroup>
  <IsTestProject>false<IsTestProject>
</PropertyGroup>

假的

对于引用XUnit的库来说，这对我来说是有效的，而XUnit不是测试库，它也应该对NUnit有效。

是否检查了项目文件中是否有以下条目：

<ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>

{3AC096D0-A1C2-E12C-1390-A8335801FDB}；{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}

它将项目定义为测试项目（旧式）

您的解决方案中有两个项目？该解决方案还有几个其他项目，其中一些确实是测试项目。您需要提供更多信息。你想创建一个测试项目还是其他什么？不，我不想创建一个测试项目。这应该是引用NUnit的常规.net标准2.0库。它不包含任何测试，但被测试项目引用（该项目称为“UnittestHelpers”）。我编辑了带有附加说明的帖子。这没有更改项目图标，也没有阻止测试输出中出现异常。csproj文件中没有entru这没有更改项目图标，它也没有阻止测试输出中的异常。
