Using Feature Flags to Enable Testing in Production

How do you know your feature is working perfectly in production? If something breaks in production, how will you know? Will you wait for a user to report it to you? What do you do when your staging test results do not reflect current production behavior? In order to test proactively as opposed to reactively, try testing in production! You will have an increased accuracy of test results, your tests will run faster due to the elimination of bad data, and you will have higher confidence before releases. This can be accomplished through feature flagging, canary releases, setting up a proper CI/CD pipeline, and data cleanup. You will leave this talk with strategies to mitigate risk, to better your understanding of the steps to get there, and to shift your company’s testing culture, so you can provide the best possible experience to your users. At the end of the day, we don't care if your features work in staging, we care if they work in production. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Testing in Production

React Summit Remote Edition

React Summit Remote Edition 2021

As developers, we release features daily – but how do you ensure those features are working properly in production before you release them to all your users? If you ask me, the answer is feature flags! Feature flags are beneficial because they allow you to test your code in production, perform canary releases, and even conduct A/B testing. The power of React makes it easy to implement these flags. We will walk through how to easily create a feature flag in the UI, install dependencies with npm, and implement your feature flag in your react app. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
