Yamal worked on enhancing automated UI testing capabilities for the Telefonica/mistica-android repository by introducing stable test identifiers to key Compose UI components. Using Kotlin and Jetpack Compose, Yamal implemented test tags for input fields, character counters, and checkboxes, enabling more reliable and maintainable UI tests. The approach centralized test tagging, reducing test flakiness and streamlining continuous integration processes. By focusing on testability and maintainability, Yamal’s contributions improved the reliability of automated QA cycles and accelerated validation of UI changes. The work demonstrated a solid understanding of Android development, UI testing strategies, and the practical application of Compose’s testing APIs.
