Configure Katalon Runtime Engine version for TestCloud execution on TestOps

Last updated: July 2026

TestCloud uses Katalon Runtime Engine to execute test scripts created in Katalon Studio. When scheduling a test run on TestOps, you can specify which Katalon Runtime Engine version to use to ensure compatibility with your scripts and browser requirements.

In the Create Automated Test Run page, expand the Advanced Settings panel and to configure the Katalon Runtime Engine version. When you set the Katalon Runtime Engine version to Latest, the scheduler will select the most recent Katalon Runtime Engine version that is compatible with TestCloud to execute.

Select latest KRE version

For TestCloud environments:

  • Latest: newest version compatible with TestCloud (for example, Katalon Studio v11 or v12 in the future).
  • Latest 9.x: newest version within the 9.x series (9.7.5).
  • Latest 10.x: newest version within the 10.x series (10.4.3).
  • New Default: Latest 10.x is now the default for all new schedules.
  • Existing scheduled test runs previously set to the generic Latest tag will be automatically migrated to Latest 9.x (9.7.5).

Each Katalon Runtime Engine version supports a different set of browser versions. Use the table below to compare the latest Katalon Runtime Engine options and see the corresponding supported browsers for each version.
