I agree with Olaf, the way to do it is to change the pdf into text. Whether
that is possible or not depends on how the pdf was made -- sometimes things are
saved in pdf as images not as characters then the only way is by OCR.
There are many ways to get from the test to the code
How many page are you dealing with?
