From FirefoxDriver to Marionette, Mozilla pulls the strings

on YouTube ↗35m

" summary

Marionette is a new automation server integrated into Gecko (launch with -marionette) that can switch between setContext Chrome/content so tests manipulate Firefox UI and web pages; it adds executeScript features like importScript and persistent globals plus a tiny JS test library with assertions and wait helpers; typing/clicks inject native-like events into the event queue; some JSON Wire commands are not yet implemented so interoperability uses a selenium proxy translates JSON Wire to Marionette’s debugger socket protocol; lands on nightly and targets Firefox 24.
