This is a hands-on succinct introduction to using Katalon’s comprehensive toolset for both exploratory and scripted (automated) testing. Use it to test Web and mobile UI (Katalium). It tests both SOAP and RESTful APIs. It enables BDD Cucumber to express test scenario in natural language.

NOTE: Content here are my personal opinions, and not intended to represent any employer (past or present). “PROTIP:” here highlight information I haven’t seen elsewhere on the internet because it is hard-won, little-know but significant facts based on my personal research and experience.

Katalon leverages open-source browser control engines Selenium for web UI and Appium for mobile UI.

Their top people (with an address in Atlanta, GA) make money by charging $8,000 for training, $5,000/year for support, and licenses for enterprise features to run CI/CD at scale.


It’s marketing website is katalon.com. The product is rated well against its competitors.

Ketalon began in 2017.

  • SoapUI
  • Ranorex Studio
  • TestIO
  • Telerik Test Studio
