Beta testing is a type of user acceptance testing where the software is released to a limited number of end-users to obtain feedback and ensure that the product is working as expected in a real-world environment. The main goal of beta testing is to place the software in the hands of actual users outside of the engineering team to discover any flaws or issues from the user's perspective.

In the context of Statsig, beta testing could involve using feature gates to expose new functionality to a select group of trusted users such as teammates, company employees, and beta customers before launching publicly. This allows you to validate the new functionality and user experience in a controlled manner, and monitor production system health before launching broadly.

If issues are identified during the beta testing phase, they can be addressed before the software is released to a larger audience, thereby reducing the risk of a negative user experience.
