Question

I’m testing two objects (and a collection of them) but it fails even though they have the same type:

I have done some research and its maybe because of the references, which they could be different. However, its still the same type and I don’t know what Assert method to use. (The CollectionAssert.AreEquivalent also fails).

Edited

I’m also trying to check if the values of each field are the same, in that case, should I do an Assert.AreEqual for each field?

— thanks, all of the answers were helpful

If you want to compare values for your dto objects then you have to override Equals and GetHashCode methods.

For example given the class:

public class DTOPersona
{
    public string Name { get; set; }
    public string Address { get; set; }
}

If you consider that two objects of DTOPersona class with the same Name (but not Address) are the equivalent objects (i.e. the same person), your code could look something like this:

public class DTOPersona
{
    public string Name { get; set; }
    public string Address { get; set; }

    protected bool Equals(DTOPersona other)
    {
        return string.Equals(Name, other.Name);
    }

    public override bool Equals(object obj)
    {
        if (ReferenceEquals(null, obj))
        {
            return false;
        }
        if (ReferenceEquals(this, obj))
        {
            return true;
        }
        if (obj.GetType() != this.GetType())
        {
            return false;
        }
        return Equals((DTOPersona) obj);
    }

    public override int GetHashCode()
    {
        return (Name != null ? Name.GetHashCode() : 0);
    }
}
