C# ASP NET MVC 5测试方法实体异常

我在VisualStudio2015有一个MVC5项目。 我首先使用ADO实体数据模型创建了我的域模型数据库，并且我有一个自定义标识（我不知道它是否重要），在这里之前，一切都正常工作。问题是当我开始创建UnitTest类时。首先我用鼠标右键点击并选择CreateUnitTests，所以我做了类似的事情

    [TestMethod()]
    public void PermissionsTest()
    {
        GroupController controller = new GroupController();
        var result = controller.Permissions("1") as ViewResult;
        Assert.AreEqual("Details", result.ViewName);
    }

我也将我的MVC项目引用放入了我的测试项目中，并更新了app.config，添加了我在MVC项目中使用的连接字符串。 但我收到一个例外：

  Result Message:   
  Test method Controllers.Tests.GroupControllerTests.PermissionsTest threw exception: 
  System.Data.Entity.Core.MetadataException: Schema specified is not valid. Errors: 
  Models.Domain.Models.ssdl(2,2) : error 0152: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

有人能帮我吗

根据Wikitor的建议，我的app.config如下所示：

u忘记了entityFramework的配置部分：）

感谢Wiktor，我尝试在我的项目中添加相同的标记“entityFramework”，现在我有了System.TypeInitializationException:“System.Data.Entity.Internal.AppConfig”的类型初始值设定项引发了异常。-->System.Configuration.ConfigurationErrorsException:配置系统未能初始化-->System.Configuration.ConfigurationErrorsException:无法识别的配置节entityFramework。你知道问题出在哪里吗？发布我的app.config会有帮助吗？我会在上面更新我的问题，也许你把它放错地方了。我很想帮忙，但现在我不在家。祝你好运，希望你能解决这个问题。我过去也有过类似的问题：（叶会更新）help@diegocolliMVC项目中有两个WebConfig.cs文件。请确保此文件位于\Views文件夹之外的文件中。我想您忘记了这一点。我想这会有所帮助。我更新了anwser。
