Moq object for testing

public class WebSDb4 : DbContext { public DbSet<User> Users { get; set; } public DbSet<UserData> UserDatas { get; set; } public DbSet<Note> Notes { get; set; } public DbSet<Session> Sessions { get; set; } } 

How to correctly write moq for such a context?
PS I do not know whether it is necessary to throw descriptions of all models, it will turn out quite volume.
