Script View

* Notes:

  • Use the import statement in a test script to allow referencing to classes.
  • All of Katalon’s default imported classes is displayed in the expanded section
  • In each import statement, the name after “as” is an alias for the class. The alias for each class can be changed, and classes are essential for composing a test script.

Katalon Studio supports keyword-driven testing for your test cases. All keywords are categorized into WebUI, Mobile, and WebService packages accordingly. Select Ctrl + Space to view these packages and functions from the imported classes.

 Step 3: In this scenario, create a Web application test script to utilize the Web UI built-in keywords. Enter the syntax (= WebUI) into the editor to use a built-in WebUI keyword.
