Will Katalon Studio become operational on top of Selenium 4 in future? — I am negative.
One more factor : Selenium 4 deprecated the concept of “Desired Capability”
7. Deprecation of Desired Capabilities
Desired Capabilities were primarily used in the test scripts to define the test environment (browser name, version, operating system) for execution on the Selenium Grid.
In Selenium 4, capabilities objects are replaced with Options. This means testers now need to create an Options object, set test requirements, and pass the object to the Driver constructor.
Listed below are the Options objects to be used going forward for defining browser-specific capabilities:
- Firefox – FirefoxOptions
- Chrome – ChromeOptions
- Internet Explorer (IE) – InternetExplorerOptions
- Microsoft Edge – EdgeOptions
- Safari – SafariOptions
I guess, the deprecation of Desired Capability has significant impacts to the Katalon Studio’s code base internally. Katalon Studio has implemented quote a lot of features for “Desired Capability”, for example:
I think, Katalon Stuido is so much dependent on Selenium3’s Desired Capability that they would not be able to move to Selenium4.
I doubt if the projects created by users on Selenium3 (current Katalon Studio) can be migrated to be operational on Selenium4.
