Fighting Flaky Tests at Scale

Flaky UI and unit tests have long been a bane for many mega repositories at Block. In this talk, we will share our journey of tackling flaky tests head-on through both offensive and defensive strategies. Learn how we implemented key changes to our engineering culture and processes to gain control over these elusive issues. Join us to discover practical insights and actionable steps to improve the reliability of your test suites at scale.
