Example implementations relate to determining visual testing coverages. Some implementations may include a principal application screen identification engine to identify, based on an image processing analysis of a set of screenshots of an application under test, principal application screens that represent a set of test executions of the application under test. Some implementations may also include a user interface element identification engine to identify user interface elements in the principal application screens. Some implementations may also include a visual testing coverage engine to automatically identify, based on an analysis of gaze data and the user interface elements, a visual testing coverage of the application under test.
