那些遇到过的问题

MSTest因为看似没有理由而挂起

Jul*_*ian 6 teamcity mstest .net-4.0 windows-server-2008

<TLDR>
在"等待运行/代理"时,从命令行运行MSTest测试会挂起而不会出现任何错误或超时.原因可能是"队列中没有运行",但为什么会这样,我不知道,因为完全相同的测试在另一台机器上运行得很好.
</ TLDR>

我们最近从在测试机器上评估TeamCity,到在我们的生产环境中安装它.在迁移了我们所有的构建配置之后,我们突然遇到了MSTest测试的问题:没有人会运行.

在调试了我们能想到的所有内容之后,我们认为我们已经排除了与TeamCity有关的任何事情.我们仍然认为这与MSTest直接相关.作为重现我们问题的简单方法,我在Visual Studio中创建了一个测试解决方案MSTestTest(C#4.0).

它有一个项目MSTestTest与一个类Class1:

namespace MSTestTest
{
    public static class Class1
    {
        public static string Foo()
        {
            return "Bar";
        }
    }
}

它有另一个项目MSTestTestTest,它有一个MSTest测试类UnitTest1:

using MSTestTest;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace MSTestTestTest
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            Assert.AreEqual("Bar", Class1.Foo());
        }
    }
}

编译解决方案,并将其两个DLL(MSTestTest.dll和MSTestTestTest.dll)复制到我们的旧测试服务器和新的生产服务器.在两台服务器上,我编辑了MSTest.exe.config文件,将详细的日志记录信息写入C:\ Temp\MSTestTrace.log(如此处所述).

在测试服务器和生产服务器上,然后从命令行运行测试,如下所示:

mstest /testcontainer:MSTestTestTest.dll /resultsfile:results.trx

在测试服务器上,我立即获得了成功的测试结果:

我已经让服务器运行了几个小时,但没有任何反应.没有超时,没有错误,没有任何错误.在这一点上,我完全被困在哪里继续.

我也尝试从管理员运行MSTest的地方运行命令提示符,但这似乎没有任何区别.

任何关于我的下一步应该是什么的建议都将受到欢迎!

问题是由于Visual Studio 2010和Visual Studio 2012并排安装时MSTest出现错误.解决方案是为Visual Studio 2010安装Service Pack 1.

我通过在事件查看器中查看Windows日志>应用程序来实现这一点.在那里我发现源VSTTAgentProcess的一个错误(在我查看过的任何MSTest跟踪日志中都没有出现错误):
