[TDD] Examples of Pojo Free Code?

Mark,

Typically I've used the data object as a parameter to the domain object consctructor, and provided a getter for when (if) I needed to recover the primitive for some reason. Often the user (ORM in this case) doesn't actually need a data-only object, anyway. It just needs some bean-pattern getters and setters for the fields it's to understand. - George -- ---------------------------------------------------------------------- * George Dinwiddie * Software Development Consultant and Coach ---------------------------------------------------------------------- |

George - thanks (BTW with Ron you seem to be the person I know of the most mailing lists - we need to get you some more work :-) I think I touched on your wrapper approach in my previous email. Like you I have used it in the past as an approach but it requires additional discipline from the dev team. Scrum already tries their discipline and I wish to conserve its use :-)

LikeAll successful programming requires discipline. I've found that TDD makes the discipline easy, combining it with ease of work and peace of mind. - George -- ---------------------------------------------------------------------- * George Dinwiddie * Software Development Consultant and Coach ---------------------------------------------------------------------- |

George - we agree. Here's how I think of discipline. Most people have only 80-100 units at one time, asking them not to use Setter's or Classes that Eclipse helpful pops up might cost 10 units. I would rather use those 10 units on practicing TDD without outside help in the months after taking a course from me :-)
If it helps George many people don't realize how unique you're - you might have 250 units of discipline at one time. However your world is not the world of others.
Cheers Mark

Units of discipline is an interesting way to look at it. I suppose that is analogous to velocity or capacity. The way I look at it is more from a learning perspective. You give people a whole bunch of new situations to look for and new ways that they are supposed to respond and they'll either freeze up or go back to the way they are used to doing it. You give them one or two techniques or ideas and let them practice and rather quickly they'll be hungry for more.? What I tend to do when I first get access to a client's code is go over it to try to understand it and look for smells along the way. Once I have identified a handful or so I will prioritize them by what seems either most egregious or most prevalent/widespread. I will point out one or two (I used to start with three, now I tend to start with two.) I will also ask questions about anything that seems unusually confusing or out of place.? The first time around I usually just provide the information and see what they do with it. Sometimes they fire back a lot of follow up questions, sometimes they get defensive, and sometimes they just proactively start looking for the smells themselves or even removing them. Each of those reactions is a situation that can be coached, but each requires a slightly different strategy to get through.?
