virtual modifier for the Id in the 'Entity' class

[ElMehdiSmiri]

@CesarD Why do we need the virtual modifier for the Id in the Entity class?

public abstract class Entity : IEntity
{
	protected Entity()
	{
	}

	protected Entity(Guid id) : this()
	{
		Id = id;
	}

	/// <summary>
	/// The identifier of the entity
	/// </summary>
	public virtual Guid Id { get; }
.....

Wouldn't you need it to perform the tests? 🤔

[CesarD]

Yup, pretty much for that. Mainly to let anyone override the property behavior in a derived class, but mostly useful for overriding its value during mocking for testing.
