What are features in delta testing?
In delta testing, products or releases are broken down into a collection of features and experiences. Each one represents an area of your product you want users to test and provide feedback on.
Each delta testing feature includes a brief, directive Activity that tells your testers how to complete a given task. Activities can be exploratory (i.e., “Go use this feature”) or explicit (i.e., “Complete these 5 steps”), but the goal is gaining meaningful insight into the testers' experience with that part of your product.
