Terminology

Profile

A collection of test scenarios. A Profile also defines the Viewports used during testing. Each Profile can include multiple Viewports and Scenarios.

Scenario Defaults

A set of configuration options at the Profile level that apply to all its associated Scenarios. These settings, however, can be overridden at the Scenario level.

Scenario

Represents a single page on your site that you want to test. Every Scenario is associated with one Profile.

Viewport

Defines the browser window size used during testing. Most commonly set to mobile, tablet, and desktop breakpoints. When the module is installed, a set of Viewports will be automatically generated from the default theme's defined breakpoints.
