构建定义
我正在使用与“构建和发布”配置相同的计算机。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，并且它们运行良好，下面将提及我的用于构建定义的配置
发行目的地
成功构建定义并执行测试脚本后，我的下一个计划是从“测试中心”中的“测试计划”运行“自动化测试”。我也将测试脚本与测试用例相关联。请查看我的发布定义的图像，其中我已使用“测试运行”选择“测试运行”
从测试中心的测试计划执行自动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。

最佳答案
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。它应该与Win Server 2008 R2上的已知问题有关。请参阅以下文章以了解详细信息：
Team Foundation Server: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
但是，该错误已由Windows团队修复，并且他们已经
为此发布了QFE。您可以找到QFE here。你会
需要在所有AT上安装它。
因此，在应用此修补程序后，只需尝试安装此修补程序并重新启动计算机，然后重试即可。
您也可以尝试使用博客中列出的初始变通办法：
打开IIS管理器
在“连接”窗格中，确保已选择AT的名称。
在中间窗格（标题为“主页”）中，确保您
在“功能视图”（底部）中，然后向下滚动到“管理”
部分。
双击“配置编辑器”图标。
中间窗格现在应具有标题“配置编辑器”。
在“部分”下拉顶部附近，展开
system.applicationHost并选择“ webLimits”。
现在，您应该看到一堆属性值对，其中之一是
名为“ minBytesPerSecond”。它的值最像240。您将
希望降低此值以解决该问题。
此外，另一种可能是它是由代理服务器引起的，只需尝试绕过代理服务器，然后再次进行检查。
