# Webcast Recording | How Optimizely Tests Features and Feature Flags 300% Faster with Cypress

June 19, 2020

By The Cypress Team

Last week, our VP of Engineering, [Gleb Bahmutov](https://twitter.com/bahmutov?ref=cypress-io.ghost.io), Software QA Engineer at Optimizely, Todd Seller, and Engineer Manager in Quality at Optimizely, [Jeff Sing](https://twitter.com/joptimizely?ref=cypress-io.ghost.io), presented a live webcast on how [Optimizely](https://www.optimizely.com/optimization-glossary/feature-flags/?ref=cypress-io.ghost.io) tests features and feature flags 300% faster with Cypress.

Some of the key topics they covered include:

-   How [Optimizely](https://www.optimizely.com/optimization-glossary/feature-flags/?ref=cypress-io.ghost.io) chooses when to write automation tests for feature flags
-   How they increased new feature coverage by 40%, and decreased incoming issues by 70%.
-   How [Optimizely](https://www.optimizely.com/optimization-glossary/feature-flags/?ref=cypress-io.ghost.io)’s QA team has reduced their untested code from 28% to 0% using Cypress.

The questions we received were all fantastic - thanks to all who attended the live broadcast via Zoom, and to those who asked live questions via Slido. ********************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************You can watch the webcast recording below:********************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************
