Hello Rajesh,
Thank you for your answer.
We've run our behat tests on Firefox 45 and 46, and Chrome. I believe it's a configuration issue.
We're still working on it, will tell you if we find something.
Hello Rajesh,
The problem comes from Feedback Poodll; see https://github.com/justinhunt/moodle-assignfeedback_poodll/issues/1
Thx again.
