  • Bingo! | Samsung North America

    Designed a fully functional automated framework to test the Translations for Samsung Voice App. The app supports more than 50 languages and testing every single country/language was a nightmare for manual testers! it takes a long time to test and human eyes can easily miss translations for foreign languages. For this framework, I designed automated assertion using Java Resource Bundle and test loaders to get the right translation and ensure the app shows it. The framework saved hundreds of hours of manual testing per cycle and the translation user stories become the smallest size of all.
