You will need a library like PDFBox for this

  1. Add it and all its dependencies to JMeter Classpath

  2. Restart JMeter to pick the .jars up

  3. The simplest code to write a JMeter Variable into a PDF file would be something like:

    def document = new org.apache.pdfbox.pdmodel.PDDocument()
def page = new org.apache.pdfbox.pdmodel.PDPage()
document.addPage(page)

def font = org.apache.pdfbox.pdmodel.font.PDType1Font.HELVETICA_BOLD

// Start a new content stream which will "hold" the to be created content
def contentStream = new org.apache.pdfbox.pdmodel.PDPageContentStream(document, page)

// Define a text content stream using the selected font, moving the cursor and drawing the text "Hello World"
contentStream.beginText()
contentStream.setFont(font, 12)
contentStream.moveTextPositionByAmount(100, 700)
contentStream.drawString(vars.get('data'))
contentStream.endText()

// Make sure that the content stream is closed:
contentStream.close()

// Save the results and ensure that the document is properly closed:
document.save('path-to-your-file.pdf')
document.close()

  • Your `${data}` variable has some characters (i.e. line breaks) which are not allowed in PDF strings, you either need to remove the line breaks or split the `${data}` variable into an array of strings and call `drawSting()` function for each line: https://stackoverflow.com/questions/46644570/pdfbox-u000a-controllf-is-not-available-in-this-font-helvetica-encoding – Dmitri T Jul 13 '22 at 10:23
