Automated Testing

for Set-Top Boxes and OTT devices

The Stb-tester Platform

Stb-tester issues commands to your device-under-test in the same way a real user does (typically using an infrared remote control).

Stb-tester then checks the behaviour of the device-under-test by analysing the device’s video output, validating what a real user would see.

The Stb-tester HDMI Nodes are small boxes that sit on your premises connected to your devices-under-test. They capture video from your devices, and execute your automated test scripts.

Using our secure web-based portal you can see live video from your devices, control them manually, run automated tests, and view test results.

Case study

In November 2015 YouView launched on a range of Sony Bravia televisions across the UK. The biggest technical challenges of the project were in the integration, with frequent releases from YouView, Sony, MediaTek, and Google — often more than one release per week, and each release needed comprehensive testing. Read how supported YouView's launch on Sony Bravia TVs.

  • Stb-tester has helped ActiveVideo to accelerate the continuous integration of the CloudTV software with true set-top-box test automation. The powerful APIs combined with outstanding and timely support made it easy to integrate stb-tester into our test environment. The result is better test coverage and an increase in overall efficiency.

    We wouldn’t have been able to reliably make so many feature improvements to YouView without the use of stb-tester within our overall testing process.

    Stb-tester has made it possible for us to provide test facilities for colleagues in India, as well as in Belgium, who are stuck at home because of the coronavirus crisis. I can't stress enough how crucial this Stb-tester infrastructure is for us nowadays. Our colleagues rely on it for being able to continue their work.

    Stb-tester is an important part of Lounge Logic’s continuous integration process. A full test suite can be developed quickly and easily, which saves us time and resources and helps us to quickly find new bugs and regressions.
