File upload with invalid path doesnt fail test - karate

Question

Below is the sample code which is suppoe to fail as the file path is invalid.
Scenario: test input
* driver "https://fineuploader.com/demos.html"
* print "performing file upload"
* input("[name='qqfile']","in valid path")
* print "done file upload"
I see the error on the console

I was expecting test to fail but surprisingly it's passing. I looked into documentation but did not find anything specific to this scenarios.
Is this is expected behaviour, or I am doing some mistake in understanding?

Answer 1

Karate's file upload (input()) works similar to Selenium WebDrivers sendkeys(). It just does setting the text without validating is it file type and a path, Which I think is ok and as per design. May be as suggested Peter assertion can help at some extent to confirm file upload works.
