NTS: Reliable Device Testing at Scale

NTS: Reliable Device Testing at Scale

摘要

At Netflix, we test hundreds of different device types every day, ranging from streaming sticks to smart TVs, to ensure that new version releases of the Netflix SDK continue to provide the exceptional Netflix experience that our customers expect. We also collaborate with our Partners to integrate the Netflix SDK onto their upcoming new devices, such as TVs and set top boxes. This program, known as Partner Certification, is particularly important for the business because device expansion historically has been crucial for new Netflix subscription acquisitions. The Netflix Test Studio (NTS) platform was created to support Netflix SDK testing and Partner Certification by providing a consistent automation solution for both Netflix and Partner developers to deploy and execute tests on “Netflix Ready” devices.

Over the years, both Netflix SDK testing and Partner Certification have gradually transitioned upstream towards a shift-left testing strategy. This requires the automation infrastructure to support large-scale CI, which NTS was not originally designed for. NTS 2.0 addresses this very limitation of NTS, as it has been built by taking the learnings from NTS 1.0 to re-architect the system into a platform that significantly improves reliable device testing at scale while maintaining the NTS user experience.
