VsTest NUnit xml.document .NET核

Question

我在NUnit Core2.0项目中创建了.NET测试。我想在VSTS发行版中使用VsTest - TestAssemblies运行它们。当我在VSTS中为我的DLL运行这个步骤时，我得到以下错误(或者更确切地说是警告)，并且没有发现任何测试。当我在本地计算机上运行VsTest.console.exe时，同样的DLL会工作。

为什么xmlDocument.dll是在我的本地机器上发现的，而不是在VSTS上发现的？

在本地文件夹中，我也没有XmlDocument.dll。

Answer 1

我遇到了同样的问题，并最终放弃了"VsTest - TestAssemblies“任务，因为我意识到有一个".NET核心”任务，可以将命令设置为测试。

在运行.NET Core2.0时，这将根据需要自动运行NuGet、恢复和构建。因此，运行用.NET核心项目编写的所有测试所需的唯一任务就是。

Answer 2

我也遇到了同样的问题，但是在将System.Xml.XPath.XDocument NuGet包添加到测试项目之后，它就运行了。

Answer 3

我也遇到了同样的问题，但是在我安装了最新和稳定版本的System.Xml.XPath.XmlDocument之后，问题就消失了。
