How to Test Feature Flags Without Breaking Production

from Software Testing with Fexingo: QA, Automation, and Reliable Software Engineering Hosted by Fexingo

Feature flags are everywhere in modern software, but they can quietly break your test suite and your production environment if you don't approach them carefully. In this episode, Lucas and Luna talk through the hidden dangers of feature flag testing—from stale flags that linger for years to the perils of testing both branches of a conditional. They walk through a real example of a company that shipped a broken feature because their tests only covered one configuration, and they share practical strategies: how to test flag permutations, how to keep your test matrix from exploding, and how to build a kill-switch that actually works. If you've ever wondered why a feature worked in staging but fell apart in production, this episode gives you a concrete way to think about it. No abstract theory—just the kind of pragmatic QA thinking you can apply today. #FeatureFlags #SoftwareTesting #QA #TestAutomation #ReliableSoftware #ContinuousDelivery #DevOps #TestStrategy #ConfigurationManagement #ProductionTesting #KillSwitch #TestCoverage #CI #Technology #FexingoBusiness #BusinessPodcast #SoftwareEngineering #TestingInProduction Keep every episode free: buymeacoffee.com/fexingo
