I don't. If you (generic you) have separate "write the code" and "test
the code" phases, your project is in trouble. You can probably get away
with it if it's a tiny throw-away script, but for anything more
substantial, you should be testing *as you are writing*. The two need to
go in parallel.
I don't follow full-blown test driven development where you write the
test before you write the code, but still, the time to find out your
infrastructure is fundamentally broken is *before* you have finished it,
not three months later when you have built the entire app on top of it.
