vstest.console.exe在UWP单元测试项目中崩溃＆＃34;根级别的数据无效。＆＃34;

Question

尝试使用vstest.console.exe运行UWP单元测试项目，我使用MSBuild生成appx包，并调用：

app.post("/follow", function(req, res){
    var follow = {follower_id:currentUser.id, followee_id:user_id};

    connection.query('INSERT INTO follows SET ?', follow , function(err, result) {
        if (err) throw err;
        res.redirect("/");
    });
});

但是得到：

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\Extensions\TestPlatform> ./vstest.console.exe C:\builds\droplocation\Uwp.UnitTesting\AppPackages\Uwp.UnitTesting_1.0.0.0_x86_Debug_Test\wp.UnitTesting_1.0.0.0_x86_Debug.appx

当我更改Microsoft (R) Test Execution Command Line Tool Version 15.5.0 Copyright (c) Microsoft Corporation. All rights reserved. Starting test execution, please wait...

vstest.console.exe

为：

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\Extensions\TestPlatform

它适用于使用VS2017 Professional的本地计算机，但在使用删除构建服务器上的构建代理程序调用时，它仍然是相同的：

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TestWindow

奇怪的是，当我尝试在构建服务器上手动运行它时，它崩溃了以下输出：
