我在Visual Studio 2013中有一个CodedUI测试项目。按照说明将SpecFlow与CodedUI API集成后，我在FeatureSetup中收到以下错误（已打开程序集绑定日志记录）

此解决方案的packages.config个文件：
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="AutoMapper" version="3.3.0" targetFramework="net40" />
<package id="CompareNETObjects" version="3.01.0.0" targetFramework="net40" />
<package id="ImpromptuInterface" version="6.2.2" targetFramework="net40" />
<package id="SpecFlow" version="1.9.0" targetFramework="net40" />
<package id="SpecFlow.Assist.Dynamic" version="1.0.2" targetFramework="net40" />
</packages>
在SpecFlow.Assist.Dynamic DLL的“属性”中，CopyLocal设置设置为true。构建解决方案后，bin\Debug文件夹中包含SpecFlow.Assist.Dynamic.dll，但TestResults文件夹中当前测试运行的文件夹不包含此DLL。它确实包含这些DLL：
我打开并关闭了Visual Studio，卸载并重新安装了NuGet包，在本地删除了包源，清理，重建，重新启动，手动删除bin\Debug文件夹并重建......列表继续。我仍然得到同样的例外。
答案 0 :(得分：1)
我不知道它是否符合设计要求，但MSTest不会将程序集部署到测试文件夹，除非在测试或测试代码中至少使用该程序集中的一种类型。因此，如果您通过反射实例化类型和汇编，那么您将遇到问题。
简单的解决方案是做两件事之一：
var dummy = new TheType()
