I want to integrate STB tester with Appium so that I can automate video validation test cases of my app. Could anyone give me some tips where to start?
I have setup STB tester and Appium. What steps should I do next to proceed further?
Well, if I understand correctly STB tester captures video only through HDMI- is your app and device capable of that ?
If yes than you could probably ignore the remote control part of the tester or send dummy commands, then just use the analyzed video results in parallel to appium.
Here's an example of integrating stb-tester and Selenium: Add visual verification to your Selenium tests with stb-tester. Both Selenium and Appium use Webdriver to interact with the device under test, so you may find this article useful.
