Entity Framework Mapping - Area Code

Question

I’m starting to work on a DDD project. I happen to be having a lot of doubts, and as much as I research, it gets more and more confused.

I created this classe:

public class Teste {
    public int Id { get; set; }
    public string Nome { get; set; }
    public string Sobrenome { get; set; }
}

And this interface

public interface ITesteRepository
{
    void Add(Teste queryResult);
    void Update(Teste queryResult);
    void Delete(Teste queryResult);
    IQueryable<Teste> GetByTesteId(int  testeId);
}

I know I need to create the mapping now, but I’m not sure how to start, I’ve already researched the Internet, if anyone has any explanation to help me, making it easier for me to understand, or some example I can follow.

Edit

It would be something like:

public class ClienteConfiguration : EntityTypeConfiguration<Cliente>
{
    public ClienteConfiguration()
    {
        HasKey(c => c.ClienteId);

        Property(c => c.Nome)
            .IsRequired()
            .HasMaxLength(150);

        Property(c => c.Sobrenome)
            .IsRequired()
            .HasMaxLength(150);

        Property(c => c.Email)
            .IsRequired();

    }
}

But I wanted to know how to do it, what the logic is.

I think this example might help you, Mariana.

 public class TestDriveRepository : GenericRepository<TestDrive>, ITestDriveRepository
{
    public TestDriveRepository(DataContext context)
        : base(context)
    {
    }

    public IEnumerable<TestDrive> GetByFilter(DateTime? initialOpeningDate = null, DateTime? finalOpeningDate = null, bool onlyEnabled = false, bool onlyExpired = false)
    {
        var query = from td in this.Table.AsNoTracking()
                    join u in base.context.Users on td.UserId equals u.Id
                    where (!onlyEnabled) || (u.Enable)
                    select td;

        if (initialOpeningDate.HasValue)
            query = query.Where(td => DbFunctions.TruncateTime(td.OpeningDate) >= DbFunctions.TruncateTime(initialOpeningDate.Value));

        if (finalOpeningDate.HasValue)
            query = query.Where(td => DbFunctions.TruncateTime(td.OpeningDate) <= DbFunctions.TruncateTime(finalOpeningDate.Value));

        if (onlyExpired)
            query = query.Where(td => DbFunctions.TruncateTime(td.ExpireDate) < DateTime.Now);

        query = query.OrderByDescending(x => x.OpeningDate);
        return query.ToList();
    }
}

Interface:

public interface ITestDriveRepository
{
    TestDrive GetById(object id);

    void Insert(TestDrive entity);

    void Update(TestDrive entityToUpdate);


    IEnumerable<TestDrive> GetByFilter(DateTime? initialOpeningDate = null, DateTime? finalOpeningDate = null, bool onlyEnabled = false, bool onlyExpired = false);

    TestDrive GetTestDriveById(long userId);

    TestDrive GetHashForValidation(string token);

    TestDrive GetTestDriveByToken(string token);

    DbContextTransaction BeginTransaction();
}
