Feature Rollout |
Feature Test |
|
It allows you to gradually launch a new feature. |
It allows you to test multiple variations of a feature. |
|
Deals with controlled release of a feature. No data is captured. |
Data from different variations are captured to identify which one is the best. |
|
A feature is turned on/off in different environments with a simple toggle option. No code change is needed. |
A product feature is tested by creating variations with a different set of variables. |
How Does it Work?
Consider a scenario where you have deployed a feature to your application and have created a feature rollout and feature test for it.
Here, there are two possible use cases:
- Feature Rollout is running with the specified set of audience and the allocated traffic
- Feature Test is running with the specified set of audience and the allocated traffic
NOTE: If you qualify for both Feature Rollout and Feature Test, then
the Feature Test is evaluated first. In other words, it’s the Feature
Test that takes precedence over the Feature Rollout.
