Videos & Tutorials

Introductory / marketing videos:

  • Introduction to the stb-tester ONE. Physical setup of the HDMI & infrared connections; using the web interface for manual control and running automated testcases; demonstration of an example testcase against a Roku set-top box; using the interactive results interface.
  • Example test scripts. In this short video we demonstrate three test scripts that know how to navigate a menu, a grid of players, and an on-screen keyboard. This demonstrates how you can use stb-tester’s Python API to build complex behaviours into your test scripts, in a clear and maintainable way.

Tutorials for test developers:

  • Looking for inexact matches. In this tutorial we learn how to match the background of a menu’s selection indicator, regardless of the text inside the selection. We show you how to tweak stb-tester match parameters, how to test this offline (on your own PC) using stbt-docker, and how to debug image-matching problems.
  • Using Frame Objects to extract information from the screen. In this tutorial we use stbt.FrameObject to extract information from the screen, and we use stbt lint and stbt auto-selftest to test our Frame Objects very cheaply.
  • Navigating a menu. In this tutorial we use the Frame Object we created in the previous tutorial, to create a function that knows how to navigate the main menu. This demonstrates how you can use stb-tester’s Python API to build complex behaviours into your test scripts, in a maintainable way.
  • Performance testing: Channel change time. Measuring channel change time on a set-top box, then using Jupyter notebook and stb-tester’s REST API to explore the results interactively and generate a histogram of the measurements.
