单元测试适配器引发异常：无法加载一个或多个请求的类型。带有测试管理器的CodedUI

Question

当我尝试从Microsoft Test Manager 2015运行CodedUI测试时，我得到错误：

“单元测试适配器引发异常：无法加载一个或多个请求的类型”

从VS2013切换到VS2015后，我开始遇到此问题。 试图通过改变测试适配器来解决这个问题，但它没有用。

升级到VS2015时，对CodedUI库的引用已更新为最新版本。您可能正在运行2013年无法加载新程序集的测试代理程序。

您必须在app.config中在运行时重新绑定它们。但是，当您执行此操作时，VS2015将无法加载旧库，您必须注释掉该部分配置或其他方式。我们使用powershell脚本在构建服务器上自动取消注释该部分，因此部署到代理的是正确的配置。

您需要将以下内容添加到app.config：
