The power of testing in production

Testing in production is crucial for ensuring the reliability and performance of software. Despite thorough testing in staging environments, issues can still arise when code is deployed to production due to factors such as production-specific configurations and unexpected interactions with other systems. Testing directly in production allows developers to catch and fix these issues before they affect all users. This approach involves deploying changes to a limited number of handpicked users or using feature flagging tools to display different versions of the app to different users. By carefully planning and implementing testing strategies, developers can improve software reliability and achieve more efficient and reliable releases.
