# Production Testing

## What is production testing?

Production testing focuses on the need to regularly check in on the health of an app as it has behaved in the real world. Users want to detect changes in either their AI app behavior or the environment that it is operated in. At Distributional, we help users to confidently answer these questions. 

## How does Distributional do production testing?

In the case of production testing, Distributional recommends testing the similarity of distributions of the data related to the AI app between the current Run and a baseline Run. Users can start with the [auto-test generation](/v0.21.x/using-distributional/testing/production-testing/auto-test-generation.md) feature to let Distributional generate the necessary production tests for a given Run.<br>
