How A-B Testing Finds Bugs Before Users Do

In episode 30 of Software Testing with Fexingo, Lucas and Luna explore how A/B testing can serve as a powerful bug-finding tool — catching issues in production before they impact all users. They walk through a real-world case from a major e-commerce platform that used controlled experiments to uncover a subtle regression in checkout flow, saving millions in lost revenue. The conversation covers setting up proper statistical thresholds, avoiding common pitfalls like novelty effects and sample ratio mismatch, and integrating A/B testing with traditional QA pipelines. By the end, listeners learn a practical framework for using experimentation not just for feature validation, but as a continuous safety net for software reliability. #ABTesting #ExperimentalDesign #SoftwareTesting #QA #ReliabilityEngineering #RegressionTesting #ProductionTesting #StatisticalSignificance #FeatureFlags #ControlledExperiments #CheckoutFlow #Ecommerce #Tech #TestingStrategy #FexingoBusiness #BusinessPodcast #Technology #Podcast Keep every episode free: buymeacoffee.com/fexingo
