I am trying to do Behat testing on a plugin that requires access to the webcam video and audio, but I can't get Selenium to pick up the media feed. Any suggestions?
I am using moodle-docker on Moodle 4.x.
I have done the following:
1. Mount audio and video files:services: webserver: volumes: - /home/somewhere/mixkit-office-ambience-447.wav:/var/www/behatdata/fake_video.y4m - /home/somewhere/deadline_cif.y4m:/var/www/behatdata/fake_audio.wav
2. Verify they show up in the webserver filesystem
root@b87870f03247:/var/www/html# ls -latrh /var/www/behatdata/-rw-rw-r-- 1 1000 1000 200M Oct 16 03:44 fake_audio.wav-rw-rw-r-- 1 1000 1000 7.1M Oct 16 03:56 fake_video.y4m
3. Add chromeOptions to config.php and verify they are included correctly in the resulting array:
getenv('MOODLE_DOCKER_APP') && $CFG->behat_profiles['default']['capabilities']['extra_capabilities']['chromeOptions']['args'][] = '--disable-web-security';getenv('MOODLE_DOCKER_APP') && $CFG->behat_profiles['default']['capabilities']['extra_capabilities']['chromeOptions']['args'][] = '--use-fake-ui-for-media-stream';getenv('MOODLE_DOCKER_APP') && $CFG->behat_profiles['default']['capabilities']['extra_capabilities']['chromeOptions']['args'][] = '--use-fake-device-for-media-stream';getenv('MOODLE_DOCKER_APP') && $CFG->behat_profiles['default']['capabilities']['extra_capabilities']['chromeOptions']['args'][] = '--use-file-for-fake-video-capture=/home/www/behatdata/fake_video.y4m';getenv('MOODLE_DOCKER_APP') && $CFG->behat_profiles['default']['capabilities']['extra_capabilities']['chromeOptions']['args'][] = '--use-file-for-fake-audio-capture=/home/www/behatdata/fake_audio.wav';
4. Logs from the selenium container (formatted JSON for readability):
