【问题描述】：
我的 Visual Studio 2015 有一个 MVC 5 项目。 我已经使用 ADO 实体数据模型首先创建了我的域模型数据库，并且我有一个自定义身份（我不知道它是否重要），直到这里一切正常。问题是当我开始创建我的 UnitTest 类时。首先我用鼠标右键单击并选择创建单元测试，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 项目引用放入我的测试项目中，并更新了我的 app.config，添加了我在 MVC 项目中使用的连接字符串。 但我收到异常：
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.
那么有人可以帮助我吗？
根据 Wikitor 的建议，我的 app.config 如下所示：
<?xml version="1.0" encoding="utf-8"?>
