During the week of September 30, 2019, we used usertesting.com to conduct six tests of the mobile newcomer tasks prototype. The full results can be found in this Phabricator task. The goals of this testing were the same as with desktop, but with the added goal of understanding how the mobile experience should differ from the desktop experience. Mobile user testers were prompted with the scenario of intending to add an image to Wikipedia (whereas desktop respondents were prompted with the scenario of intending to create a new article).
