The key difference between traditional web/desktop applications and mobile applications in regression testing lies in scope, with mobile testing being more complex due to the various mobile browser combinations, device and OS combinations of Android and iOS, as well as native, hybrid, responsive, and progressive web apps. Mobile development follows agile and DevOps principles, requiring continuous testing and continuous delivery, which necessitates a comprehensive testing platform, highly scalable infrastructure, and CI/CD optimization to keep up with the fast pace of continuous delivery. By adopting a mobile regression testing plan, organizations can reduce the risks of flaky software and ensure that new features or application updates do not introduce new bugs.
