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Build和Release配置相同的机器。我已成功创建构建。使用构建我能够在构建中的Visual Studio Test Task中执行编码的UI脚本并且它们正常工作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之后，我的下一个计划是从测试中心的测试计划中运行自动测试。我还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，其中我使用Test run选择了Test Run

我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。

如果有人能够确定我遗漏了什么或者我需要解决这个问题，我将感谢你，以便我可以从测试中心的测试计划中执行自动化测试。

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.”和您的澄清。它应该与win server 2008 R2上的已知问题有关。有关详细信息，请参阅以下文章：

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，他们已经为它发布了一个QFE。你可以找到QFE here。您需要在所有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，然后再次尝试。

您还可以尝试使用博客中列出的初始变通方法：

1. 打开IIS管理器
2. 在“连接”窗格中，确保选中了AT的名称。
3. 在中间窗格（标题为“主页”）中，确保您位于“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. 中间窗格现在应该具有标题“配置编辑器”。在靠近顶部的部分下拉，展开system.applicationHost并选择“webLimits”。
6. 您现在应该看到一堆属性值对，其中一个名为“minBytesPerSecond”。它的值最像是240.您需要降低此值以获得变通方法。

此外，另一种可能性是它是由代理服务器引起的，只是试图绕过代理服务器，然后再次检查它。
