Hey everyone, this is David Nidemannsen. I am here with Martin Fowler and Kent Beck to talk for the fourth round of is TDD dead.

Today we're going to talk about the drawbacks, the cons, the pressures, the nudgings of TDD, basically the utter half of the trade-off.

We keep talking about how TDD and other testing techniques are all about trade-offs.

So to talk about trade-offs, you really have to understand the drawbacks.

Because if there are no drawbacks, there are no trade-offs.

And I think that that's perhaps one of the things that I've been most

interested in with this whole debate

is to basically illuminate

the fact that things are not free.

Nothing is free. No technique

is free, no approach is free,

and TD surely

is not free either.

And we have a number of these pressures and nudgings to talk about.

That's, I think, the paradigm to think about it with that there's nothing.

TDD doesn't force you to do anything.

Nobody forced you to do anything.

I feel like TDD nudges you in a certain direction, or it exerts

a certain pressure to follow it. It doesn't mean that it dictates that path. It doesn't mean

you have to follow that path. That's just what I've observed watching people do TDD and

watching myself do TDD at times.

And I think the first thing that I spot that I noticed relates to over-testing.
