Creating unit tests for generated PDF files using iText

Question

We use iText to read the input PDF file, then add the messaging and save the output.

PdfReader reader = new PdfReader(inputFilepath);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(outputFilename, true));
PdfContentByte over = stamper.getOverContent(1);
over.beginText();
over.showTextAligned(align, text, x, y, angle);
...
over.endText();
stamper.close();

Is there a way to read in the PDF generated in the unit test, and then check for existing text in the correct x, y coordinates?

Answer 1

Generally speaking, do not test the platform (or, in this case, the third-party libraries that you use.) Instead, the test is that you are communicating correctly with it.
