System.Xml.XmlException与dotnet测试一起发生

Question

Using .NET Core's unit testing functionality and the MSTest Framework and Adapter, I am trying to run this simple unit test:

using Microsoft.VisualStudio.TestTools.UnitTesting;

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

However even with the scaffolded dependencies:

<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>

I get this following error when using the dotnet test command:

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...

Note that this error occurs with an empty TestMethod1() and also when using the built in xUnit project template. I am using .NET Core 1.1.

Answer 1

I couldn't reproduce this issue either using MSTest Or XUnit . The possible area to look at would be the Versions of PackageReference especially MSTest and XUnit . Look up your version in Nuget and verify the version of .net standard it support.

Answer 2

The problem is your file path. At present, dotnet test cannot handle a file path that has an ampersand (ie, the & character) in it.
