Question

我遇到一个问题，即在构建Visual Studio Team Services时，我的ASP.Net Core 1.0应用程序中的xUnit测试没有被发现。

测试项目正在成功构建，但未给出测试结果。我在日志中找到有关Visual Studio Test步骤的以下消息：

******************************************************************************

Information: Additionally, you can try specifying '/UseVsixExtensions' command if the test discoverer & executor is installed on the machine as vsix extensions and your installation supports vsix extensions. Example: vstest.console.exe myTests.dll /UseVsixExtensions:true

测试编写如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using Xunit;

namespace project.tests
{
    public class ProjectTests
    {
        [Fact]
        public void PassingTest()
        {
            Assert.Equal(4, Add(2, 2));
        }

        [Fact]
        public void FailingTest()
        {
            Assert.Equal(5, Add(2, 2));
        }

        int Add(int x, int y)
        {
            return x + y;
        }
    }
}

测试在本地运行得很好，但在Visual Studio Team Services上没有。

作为参考，这是我的project.json

Answer 1

输入＆＃34; $（Build.SourcesDirectory）\ SolutionFolderName \ packages＆＃34; in＆＃34;高级执行选项\自定义测试适配器的路径＆＃34;将测试适配器设置为xUnit。有关详细信息，请参阅此链接：xUnit or NUnit with Visual Studio Online Build

<强>更新：我只是创建一个示例应用程序来测试这个并得到同样的问题。但是，如果我将xunit程序集文件复制到＆＃34; dnx451＆＃34;文件夹与test.dll一起，测试将成功完成。
