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，我能够在构建中执行 Visual Studio 测试任务 中的编码 UI 脚本，并且它们工作正常我的配置是用于构建定义的，如下所述

发布目的地

在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

通知我在测试中心的测试计划执行自动化测试失败后收到

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。

如果有人能确定我在哪里遗漏了什么或者我需要解决这个问题以便我可以在测试中心的测试计划中执行自动化测试，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。详情请参考以下文章：

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

但是，Windows 团队已经修复了这个错误，并且他们已经 为它发布了一个 QFE。您可以找到 QFE here。你会 需要在你所有的 AT 上安装它。

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。

您也可以尝试使用博客中列出的初始解决方法：

1. 打开 IIS 管理器
2. 在“连接”窗格中，确保选择了您的 AT 名称。
3. 在中间窗格（标题为“主页”）中，确保您是 在“功能视图”（底部）并向下滚动到管理 部分。
4. 双击“配置编辑器”图标。
5. 中间窗格现在应该有标题“配置编辑器”。 在靠近顶部的下拉部分中，展开 system.applicationHost 并选择“webLimits”。
6. 您现在应该看到一堆属性值对，其中一个是 命名为“minBytesPerSecond”。它的值最像 240。你会 想要降低此值以解决问题。

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，再检查一遍。
