How Smoke Tests Catch Deployment Killers in Five Minutes
from Software Testing with Fexingo: QA, Automation, and Reliable Software Engineering Hosted by Fexingo
Lucas and Luna explore why smoke testing — a lightweight automated check that runs before full regression — is the most underrated safety net in modern CI/CD. Lucas breaks down how one fintech startup cut its rollback rate by 40 percent simply by running a five-minute smoke suite on every deploy candidate. They discuss the difference between smoke tests and sanity tests, the ideal smoke-test ratio (roughly one test per ten API endpoints), and why teams that skip smoke tests often discover broken deploys via user support tickets. Luna pushes back on the notion that smoke tests add pipeline friction, and Lucas shares examples of smoke tests that caught production-breaking Kubernetes config errors within seconds. The episode closes with a look at how smoke tests fit into a broader testing pyramid strategy — and why they should never be treated as a replacement for deep functional coverage. A donation segment draws the parallel between testing safety nets and the listener support that keeps the show ad-free. #SmokeTesting #CICD #ContinuousDelivery #DevOps #TestAutomation #SoftwareTesting #QualityAssurance #TestingStrategy #DeploymentSafety #BuildPipeline #Kubernetes #FintechCaseStudy #SanityTesting #RegressionTesting #CIBuild #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
