Why Test Data Quality Matters More Than Test Coverage

Episode 12 of Software Testing with Fexingo examines why the quality of test data often matters more than the volume of test cases. Lucas and Luna dive into the 70-30 rule—70 percent of test failures trace back to data issues, not code bugs—using the 2024 CrowdStrike outage as a real-world case study. They discuss how synthetic data generation, production-like datasets, and data versioning can prevent false positives and missed defects. The episode also covers practical strategies for maintaining test data hygiene, including data subsetting and masking, to ensure your test suite actually validates the right things. A must-listen for QA engineers, automation leads, and engineering managers who want to reduce flaky tests and improve release confidence. #TestDataQuality #SoftwareTesting #QA #TestAutomation #DataHygiene #CrowdStrike #SyntheticData #TestCoverage #FlakyTests #DataVersioning #TestEnvironments #SoftwareEngineering #Technology #FexingoBusiness #BusinessPodcast #EngineeringManagement #DevOps #DataMasking Keep every episode free: buymeacoffee.com/fexingo
