从Visual Studio运行测试代理的单元测试：登录尝试失败

Question

我试图设置一个测试控制器和测试代理，供开发人员在Visual Studio中运行其单元测试时使用。我有TA和TC建立起来并相互连接。我在一个项目中创建了testsettings文件，并将Test执行方法设置为Remote Execution，并指向了Test Controller。当我尝试运行的TA一个测试，我得到以下出把在Visual Studio：

------ Run test started ------ 
Ignoring test impact data collector settings specified in the .TestSettings file. 
Failed to queue test run 'user@MACHINE 2014-08-28 08:46:31': The server has rejected the client credentials. 
The logon attempt failed 
========== Run test finished: 4 run (0:00:17.353169) ========== 

测试控制器日志如下：

V, 2156, 23, 2014/08/28, 08:46:49.494, CONTROLLER\QTController.exe, ControllerObject: AgentHello from AGENT 

我不知道为什么我收到这个登录错误当TA和TC互相交谈时就好了。我认为它可能与LoadTestResultConnectString有关，但我一直没有找到多少关于它的内容？

当控制器/代理组合还在使用VS 2013版本的控制器和代理时，在试图在VS 2015上运行负载测试时遇到此问题。

简单修复是使用VS 2013开始负载测试。
