SK broadband is the first company in the world to introduce high speed internet and is also the first company to introduce IPTV in Korea. It is one of the largest network service providers in Korea, securing approximately 8 million subscribers. Now, it focuses on producing diverse media contents and providing excellent customer experience, to maintain its role as the industry leader.

SK Broadband used to do manual scenario-based tests and did not have a sufficient tool to manage the QA process. They wanted to move away from manual testing and establish a system-based, automated process and increase their efficiency in finding defects. They needed a partner that could help them achieve this goal, and NEXTLab was the perfect company for this task.

NEXTLab has been providing SK Broadband with solutions that apply automated test technology that can manipulate and recognize UI based on black box to STB verification since 2017. Since then, through continuous cooperation, we have expanded the possible targets for automated testing from STBs to Remote Control Units(RCUs) and STBs equipped with Voice UI. Furthermore, control technology that can reproduce various failure situations has been added, leading to developing a platform that integrates and analyzes STB output images as well as logs and network packets.

Thanks to NEXTLab’s solution, SK Broadband’s Media QA Center has drastically reduced QA time. Before implementing the solution, QA engineers spent 2~3 days to manually test about 30 test cases. Now, it only takes an hour to test roughly 100 test cases at once. In addition to QA time reduction, since QA environment and methods have been established quantitatively, the test results’ credibility has increased and become a good standard for customer service quality. Overall, tests from 50% of entire QA category have been successfully automatized and efficiency in detecting and improving various defects has increased by 30%.
