Hi,
Please refer to: Migrate Katalon Studio from 8.x to 9.0.0 | Katalon Docs.

if you have migrated a BDD project from KS 8.x to 9.x

For users with BDD projects

You need to add a @BeforeTestCase listener to your project. To learn more about test listeners, see Test Listeners (Test Hooks).

  • You don’t need to modify every script in your project, you just need to add this test listener ONCE.

In the Tests Explorer panel, right click Test Listeners and create a new test listener. Then, copy and paste the following code to the listener script:

import com.kms.katalon.core.cucumber.keyword.internal.CucumberGlueGenerator@BeforeTestCasedef beforeTestCase(TestCaseContext context) {  CucumberGlueGenerator.addDefaultPackages();}
