Unit testing PDF is hard. You can, for example, use the
SimpleTextExtractor to suck out all the text from your ouput PDF, but
you don't know what font it's in, what the table borders look like, or
if the text is even visible. Off the bottom of the page? Covered by
something else? Same color as its bacground? No way to know with just
that text extractor. And finding out becomes exponentially more
difficult.
Even iText's unit tests generally involve running a program and checking
the output by opening it in a PdfReader and querying the page count.
Searching for the right text is an improvement, but it still leaves some
gaping holes.
Repeat after me: "Unit testing PDF is hard."
