tfs - Visual Studio 测试运行 : Run Coded UI automated tests from test plans in the Test hub

Question

构建定义
我使用与构建和发布配置相同的机器。我已经成功创建了构建。使用 build 我可以在 中执行编码的 UI 脚本Visual Studio 测试任务 在构建中，它们工作正常我的配置用于构建定义如下所述

发布目的地
在成功构建定义和执行测试脚本后，我的下一个计划是从测试中心的测试计划运行自动化测试。我也将我的测试脚本与测试用例相关联。请查看我的发布定义的图像，其中我使用测试运行选择了测试运行

通知 从测试中心的测试计划执行自动化测试失败后我收到的是

Deployment of release Release-11 Rejected in Deploy Test Scripts.

我添加了调试变量，似乎在创 build 置文件时，它类似于 system.io 异常。

如果有人能确定我遗漏了什么或我需要解决什么问题，以便我可以从测试中心中的测试计划执行自动化测试，我将不胜感激。

Answer 1

基于错误消息“Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.”和您的说明。它应该与 win server 2008 R2 上的已知问题有关。详情请引用以下文章:

Team Foundation Server: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

However the bug has been fixed by the Windows team and they have released a QFE for it. You can find the QFE here. You will need to install it on all of your ATs.

因此，只需尝试安装此修补程序并在应用此修补程序后重新启动计算机，然后再试一次。

您还可以尝试使用博客中列出的初始解决方法:

1. Open the IIS Manager
2. In the Connections pane, make sure the name of your AT is selected.
3. In the middle pane (titled “ Home”), make sure you are in the “Features View” (bottom) and scroll down to the Management section.
4. Double-click the “Configuration Editor” icon.
5. The middle pane should now have the title “Configuration Editor”. In the Section pull down near the top, expand the system.applicationHost and select “webLimits”.
6. You should now see a bunch of property value pairs, one of which is named “minBytesPerSecond”. Its value is most like 240. You will want to lower this value for the workaround.

另外，还有一种可能是代理服务器引起的，尝试绕过代理服务器，然后再检查。
