Discover how to implement upstream cross-project testing to prevent breaking API consumers in this DevConf.CZ 2024 conference talk. Learn about the challenges of software regressions and their impact on consumers. Explore the benefits of running consumer tests within upstream project pull requests, known as reverse dependency testing. Understand how this approach tightens feedback cycles, simplifies debugging, prevents broken releases, and increases confidence in making changes. Gain insights into implementing this strategy using tmt, packit, and COPR services without maintaining custom infrastructure. Hear about Cockpit's successful implementation of this approach with projects like SELinux and podman. Equip yourself with knowledge to improve your software development process and maintain better relationships with API consumers.
