Usually, you can decide on structure of code before implementing it. You can even have tests up and running before implementing it.

And in many cases this actually works.

You can do agile test first too.

"hey here's a feature we're pretty sure we need:

As a foo, I need to bar, So that baz

okay, write the test, make the test pass, refactor"

What about that isn't possible in agile?
