Allow me... (warning, non iText/PDF related rambling) ;)
It's not about adding unit tests to your code. It's about adding code to
your unit tests.
Well written unit tests tell you (the developer) what exactly you need
to implement to make the test run (i.e. acts as a low-level spec). When
the bar goes green you can go home happy that the code does exactly what
it needs to do... not more, not less.
Afterwards it also tells other developers how to interface with your
code, so it acts as documentation. (i.e. acts as com/lowagie/examples/)
Of course, all this relies on your ability to write good tests. I too
have seen tests that didn't test anything (but appeared to do so) - and
that's worst than no testing, because it leads to wrong assumptions and
wastes time.
For quality of code you have other tools, like checkstyle and pmd.

PS: I can't claim to be an expert in test-driven development. I've only
really got into it a few months ago because it's used here at work, but
I'm bought by it already.

I second that, yet people keep on asking for PDF Unit tests.
It's as if you are a bad Java programmer if you don't provide
Unit tests. Based on my experience, I'd rather say that writing
Unit test doesn't make you a good programmer. I have seen
lots of useless Unit test code that tells you absolutely nothing
about the quality of the code.
