However, only those videos, which are posted to the site by individual users, celebrities or musicians, will have the auto-play function during the test but the company said that it would explore to bring this feature to marketers in the future, stuff.co.nz reports.
Facebook is speculated to charge brand marketers 1 million dollars to 2.4 million dollars to show 15-second auto-play video ads on its social network.
The report said that the auto-play videos will work on Facebook's mobile apps for smartphones running Google's Android software and Apple's iOS software.
Facebook spokeswoman Momo Zhou said that during internal tests, the auto-play ads did not seem to significantly reduce battery life and the videos stop playing once a user scrolls past them in the news feed.
The report further added that the auto-play will work only with videos that users upload directly to Facebook and those from external websites such as YouTube will not work with the auto-play feature in the test and users also have the option of switching off the feature.
