The Sauce Labs podcast Test Case Scenario shares three horror stories from history about the devastating consequences of poor software development practices. Robert Tappan Morris's 1988 computer worm infected an estimated 2,000 computers, causing $10 million in damages, while a company's deployment of a 404 page update to production led to a slow-down of their chat application and internet crash, costing them millions of dollars. Another story revolves around the Oklahoma State Sex Offender Registry, where hackers could extract personal information for three years due to a SQL query string vulnerability. These examples highlight the importance of proper testing, including front-end testing, to prevent bugs from escaping into production and the need for disaster recovery drills to mitigate potential risks.
