How One Engineer Turned a Flaky Test into a Daily Reliability Report

Flaky tests are the bane of every CI pipeline — they waste developer time, erode trust in test suites, and can hide real regressions. In this episode, Lucas and Luna dive into the story of one engineer at a mid-size fintech company who got so fed up with a single notoriously flaky end-to-end test that she built a lightweight daily reliability report. They walk through the specific data she tracked: failure rate over a 30-day rolling window, root-cause categories (infra flake, timing issue, data dependency), and the automated Slack bot that posted a daily digest to the engineering channel. The report didn't just surface the flaky test — it triggered a conversation about test design that ultimately led the team to split the slow end-to-end test into smaller, more reliable integration tests. Lucas and Luna discuss the practical steps to create your own reliability report, the metrics that actually matter, and why a culture of transparency around flaky tests is better than pretending they don't exist. They also touch on how this approach shifts the incentive from 'green pipeline at all costs' to 'meaningful test coverage.' #FlakyTests #TestReliability #CI #ContinuousIntegration #DevOps #TestingStrategy #EngineeringCulture #DataDriven #SlackBot #Fintech #IntegrationTests #EndToEndTests #SoftwareEngineering #Technology #FexingoBusiness #BusinessPodcast #EngineeringPodcast #TestAutomation Keep every episode free: buymeacoffee.com/fexingo
