NYCPHP Meetup

[Justin Demaris]

One other feature that I would be interested in is friendliness to unit
tests. Is it possible to easily set up faux-objects and pass them around
without having them hit the database? Is it possible to use some of the
more complex fetching and management operations without actually hitting a
real database?

I had a debate on the values of data mapping vs active records a while ago
with a coworker and from my understanding, data mapping isn't so much
"completely different" from the active record approach as it is the next
logical evolutionary step to support the needs of large application
development. A lot of the ideas of data mapping have been filtering their
way back into simpler ORM systems like Yii that still call themselves
"Active Record".

Back to the point, how well does Doctrine 2 play with unit tests?
