Getting Started with Image Based Testing

Are you a tester who’s trying to automate something that your normal test automation tool is not recognizing? Or are you a gamer looking to create a gaming bot? Maybe you’re a combination of both. If any of those apply, this episode is for you. Today I’ll be Test Talking about the open-source, image based tool Sikuli with its core developer and maintainer, Raimund Hocke.

I think this is one of the most inspiring Test Talks to date because Raimund started the Sikulix project later in life, at a time when most people stop trying new things and become learning-stagnant. Raimund is proof that it’s never too late to learn something new, and his enthusiasm for Sikuli really comes through in this interview.

About Raimund Hocke


Raimund is the Senior Support Manager for SikuliX. Sikuli is a visual technology to automate graphical user interfaces (GUI) using images (screenshots). Sikuli Script automates anything you see on the screen. You can programmatically control a web page or a desktop application running on Windows/Linux/Mac OS X or even a Mobile Phone application running in an emulator.

  1. Hey Joe,

    have you had a chance to validate/compare the visual automation tools like sikuli/applitools/phantomcss etc. Just on how reliable they are.

    I am just thinking that it will be better to add a visual test rather than 10s of object based tests.

  2. Thanks for this. Good to associate a voice with Raimund Hocke. I used SikuliX to accomplish some automation tasks at work. I greatly appreciate Raimund Hocke taking this project on. He is responsive to issues. I am looking forward to SikuliX Version 2. Rock on, PLA

  3. Hi Joe, do you have any info on the Sikuli 2.0 release? I’ve built some POC projects in the 1.0 version for automating desktop apps for Adobe Creative Cloud, and have been really looking forward to the modernized 2.0 release with better Java integration. A year ago I read that he was looking at October 2018 for alpha releases, but I haven’t seen any significant activity, and the repo is updated to say that the 2.0 alpha is moved to 2019.
