How One Engineer Used Regression Testing to Prevent a Production Outage

In this episode, Lucas and Luna explore how one engineer at a mid-size SaaS company used regression testing to prevent a catastrophic production outage. The engineer, Sarah Chen, implemented a focused automated regression suite that caught a subtle bug in a payment processing module before it hit production. Lucas breaks down the specific techniques Sarah used: prioritizing high-risk test cases, integrating the suite into the CI pipeline, and setting up failure alerts. Luna discusses the trade-offs between regression testing and other quality assurance methods. The episode highlights concrete numbers: how Sarah's team reduced production incidents by 70% and cut regression test run time from six hours to 25 minutes. Listeners learn a practical approach to building regression tests that actually prevent outages without slowing down development. #RegressionTesting #SoftwareEngineering #QualityAssurance #CI #ProductionOutage #AutomatedTesting #SarahChen #SaaS #PaymentProcessing #CI #CI #CI #ContinuousIntegration #TestAutomation #TechDebt #FexingoBusiness #BusinessPodcast #Technology Keep every episode free: buymeacoffee.com/fexingo
