Java EE 8 Design Patterns and Best Practices

Defining a group of end users

In this step, we select a group of end users to receive a new version of an application. To define this group, a number of things need to be evaluated. Some of these evaluations include:

• The new features existing in a new version
• The localization of end users
• Business roles

The end users selected for A/B testing need to be defined and marked by the application in order to allow it to distinguish between end users with access to the new version and those without. This can be done using a cookie, filtering by IP address if the group is location-related, or by using another mechanism that grants an end user access to the new version.
