Test in more than one browser and size
Run the critical journeys in at least two browser engines, at phone and desktop width.
How to do it
Configure projects for Chromium and WebKit, and one with a phone viewport. Firefox adds a third engine. Keep the rest of the suite on one browser to save time.
How to check
The test report lists each journey passing in two engines and two screen sizes.
