Visual Studio 测试运行：从测试中心的测试计划运行编码的 UI 自动化测试

Question

构建定义

我正在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。使用构建我能够在构建中的Visual Studio 测试任务中执行编码的 UI 脚本，并且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

从测试中心的测试计划执行自动化测试失败后收到的通知是

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

我添加了调试变量，似乎在创建设置文件时，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

根据错误消息“ Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.”和您的说明。应该与win server 2008 R2上的已知问题有关。详细请参考以下文章：

\n\n

Team Foundation Server：无法从传输连接读取数据：现有连接被远程主机强制关闭。

\n\n

\n

不过，Windows 团队已修复该错误，并为其发布了 QFE。您可以在此处找到 QFE 。您需要将其安装在所有 AT 上。

\n

\n\n

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，然后重试。

\n\n

您还可以尝试使用博客中列出的初始解决方法：

\n\n

\n

\n
1. 打开 IIS 管理器
\n
2. 在“连接”窗格中，确保选择了您的 AT 名称。
\n
3. 在中间窗格（标题为 \xe2\x80\x9c Home\xe2\x80\x9d）中，确保您位于\n\n \xe2\x80\x9cFeatures View\xe2\x80\x9d（底部）并向下滚动到管理部分。
\n
4. 双击 \xe2\x80\x9cConfiguration Editor\xe2\x80\x9d 图标。
\n
5. 中间窗格现在的标题应为 \xe2\x80\x9cConfiguration Editor\xe2\x80\x9d。\n 在顶部附近的“部分”下拉菜单中，展开 \n system.applicationHost 并选择 \xe2\x80\x9cwebLimits\xe2\x80\x9d。
\n
6. 您现在应该看到一堆属性值对，其中一个名为\xe2\x80\x9cminBytesPerSecond\xe2\x80\x9d。它的值最接近 240。\n 您需要降低该值来解决此问题。
\n

另外，还有一种可能是代理服务器造成的，尝试绕过代理服务器，然后再检查一下。
