We have an API with just retrieves PDF from a Server. So when the API is hit, we get this as response.
In SOAP UI, there will be an attachment tab from which we can open the PDF file. Is there a way to do this in Karate.?
We are trying to move towards Karate
Being able to preview a PDF is for manual testing and Karate is a test-automation tool. So it is not supported and my suggestion is that you don't worry about this and move on. In my opinion this is not a mandatory requirement for you.
What is important is to be able to do a comparison. If you are doing an exact binary match, this is already possible, refer: https://stackoverflow.com/a/55147777/143475
You may be able to embed a PDF into an HTML report, refer: https://github.com/karatelabs/karate/tree/v1.2.1.RC1/karate-demo/src/test/java/demo/embed
Finally if you really insist on "opening" the PDF somehow during a test, you can use the ability of Karate to call command-line programs. For example open foo.pdf works on a Mac. Refer this: https://stackoverflow.com/a/62911366/143475
EDIT: Karate has visual testing in version 1.3.0 onwards, perhaps you can give this a try: https://github.com/karatelabs/karate#compare-image
