unit-testing - 如何在 vs 2012 中执行单元测试时消除错误

Question

    [TestMethod]
    public void Index1()
    {
        MovieDBContext db = new MovieDBContext();

            //Arrange
            MoviesController mv = new MoviesController();
            //Act
            ViewResult result = mv.Index() as ViewResult;
            //Assert
            Assert.AreEqual(result.ViewName, "Index");


    }

//Controller Method is and db object create in the same controller as method (Index) exists

公共行动结果索引（）{

        return View(db.Movies.ToList());
    }

//Error come as 初始化数据库时发生异常。有关详细信息，请参阅 InnerException。
