在 mvc4 中的实体框架工作中对 CRUD 操作进行单元测试

我正在尝试研究 mvc4 中的实体框架。我在 EF 中使用 CRUD 操作创建了一个项目。现在我想对此进行单元测试（主要是依赖注入）。我用谷歌搜索了很多网站，并尝试做模拟测试方法，

但它没有用。实际上，对 EF 进行单元测试的最佳方法是什么？创建用于测试的类或创建测试项目。这是我的 crud 操作代码，我该如何对此进行单元测试，请帮助我。

会员.cs

public class Member
{
    [Key]
    public int MemID {get;set;}
    [Required]
    [Display(Name = "Member Name")]
    [StringLength(50)]
    public string MemName { get; set; }
}

成员控制器

 public class MemberController : Controller
 {
    private SampleDataContext db = new SampleDataContext();
    //
    // GET: /Member/
    public ActionResult Index()
    {
        return View(db.Members.ToList());
    }
    //
    // GET: /Member/Details/5
    public ActionResult Details(int id = 0)
    {
        Member member = db.Members.Find(id);
        if (member == null)
        {
            return HttpNotFound();
        }
        return View(member);
    }
    //
    // GET: /Member/Create
    public ActionResult Create()
    {
        return View();
    }
    //
    // POST: /Member/Create
    [HttpPost]
    public ActionResult Create(Member member)
    {
        if (ModelState.IsValid)
        {
            db.Members.Add(member);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(member);
      }
    //
    // GET: /Member/Edit/5
    public ActionResult Edit(int id = 0)
    {
        Member member = db.Members.Find(id);
        if (member == null)
        {
            return HttpNotFound();
        }
        return View(member);
    }
    //
    // POST: /Member/Edit/5
    [HttpPost]
    public ActionResult Edit(Member member)
    {
        if (ModelState.IsValid)
        {
            db.Entry(member).State = EntityState.Modified;
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(member);
    }
    //
    // GET: /Member/Delete/5
    public ActionResult Delete(int id = 0)
    {
        Member member = db.Members.Find(id);
        if (member == null)
        {
            return HttpNotFound();
        }
        return View(member);
    }
    //
    // POST: /Member/Delete/5
    [HttpPost, ActionName("Delete")]
    public ActionResult DeleteConfirmed(int id)
    {
        Member member = db.Members.Find(id);
        db.Members.Remove(member);
        db.SaveChanges();
        return RedirectToAction("Index");
    }
    protected override void Dispose(bool disposing)
    {
        db.Dispose();
        base.Dispose(disposing);
    }
}
