The A/B Testing feature lets you experiment with different variants of your remote configuration variables to find the best performing variant based on your goals. You can then roll-out the winning variant to all your users.
Take advantage of all your default or custom user properties and user actions (such as sessions, views, events, etc.) while building the target audience for your experiment.
Use Behavioral Cohorts to set your A/B Testing goals and measure the effects of each different version of a remote configuration variable on as many users as are in a cohort.
A/B Testing doesn't require an SDK update if you already use Remote Configuration inside your application.
