Automatic Migration command not working

Question

So I'm doing an application using the MVC5 framework, and I have the default tables from the individual user accounts. Now i am trying to add my own tables,but it doesn't seem to be working.

A test class:

 public class teste
    {

        public int Id { get; set; }
        public int Nome { get; set; }

    }

    public class Entities : DbContext
    {
        public DbSet<teste> testes { get; set; }

    }

then i use the add-migration command followed by the update-database. it says it updates just fine, but no table is created. am I doing something wrong ?

EDIT:

migration (i dunno why its empty)

 public partial class teste2 : DbMigration
    {
        public override void Up()
        {
        }

        public override void Down()
        {
        }
    }

EDIT2:

I have 2 connection strings, one for the Authentication database (created by MVC) and the other one for my context. and the name matches the class of the DbContext.

  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-ESW_Proj-20141217061426.mdf;Initial Catalog=aspnet-ESW_Proj-20141217061426;Integrated Security=True" providerName="System.Data.SqlClient" />
    <add name="Entities"  connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Entities.mdf;Integrated Security=True"  providerName="System.Data.SqlClient"/>
  </connectionStrings>

You should dedicate the target connection string name for derived DbContext class in constructor like this:

public class Entities : DbContext
{
    public Entities() : base("Entities") { }

    public DbSet<teste> testes { get; set; }
}
