Media #

One of the main features of Loadero is supplying fake media feeds during tests. This feature mainly concerns services that require a webcam or microphone to fully cover app logic. By default, this functionality is not provided by Selenium or Nightwatch, but in Loadero this does not require any custom actions to accomplish.

Loadero offers fake media feed out of the box for all tests running through Loadero. During participant configuration, media type can be selected. This media feed will be used to simulate a webcam and a microphone that a physical machine could have. Different types of fake media allow simulating users with higher or lower resolution cameras.

Media types that supply only audio or only video are not provided - these scenarios should be solved on the web app itself!
Media selection is applied to Google Chrome browser only. In order to use the media feed built into Google Chrome, you can set up the media type for the participant to Default. For Mozilla Firefox browser built-in fake media feed will always be used.
Marked video files with -50dB audio feed differ from other media files as they provide more static media feed which has closer resemblence to a webcam feed.
