System.Xml.XmlException 发生在 dotnet 测试中

Question

使用 .NET Core 的单元测试功能和 MSTest 框架和适配器，我正在尝试运行这个简单的单元测试：

using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace TESTFull
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            Assert.AreEqual(1, 2);
        }
    }
}

但是，即使有脚手架的依赖项：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" />
    <PackageReference Include="MSTest.TestAdapter" Version="1.1.11" />
    <PackageReference Include="MSTest.TestFramework" Version="1.1.11" />
  </ItemGroup>
</Project>

使用dotnet test 命令时出现以下错误：

Test run for F:\Onedrive\Uni\2-1\Dev Project 1 - Tools & Practices\RESTFull\TESTFull\bin\Debug\netcoreapp1.1\TESTFull.dll(.NETCoreApp,Version=v1.1)

Starting test execution, please wait...

请注意，空TestMethod1() 以及使用内置xUnit 项目模板时会发生此错误。我正在使用 .NET Core 1.1。

Answer 1

我无法使用MSTest 或XUnit 重现此问题。可能要查看的区域是PackageReference 的Versions，尤其是MSTest 和XUnit。在Nuget 中查找您的版本并验证它支持的 .net 标准版本。

Answer 2

问题是您的文件路径。目前，dotnet test 无法处理包含与号（即& 字符）的文件路径。
