Exception Handling Statements

  • Once a test step is added as any of the control statements, it is not allowed to change into another keyword.

In Manual view

  2. Click on the drop-down icon of the Add button, then choose Exception Handling Statements.

    Refer to the following table for the usage of each statement:
    TryThis statement indicates that all steps within is monitored by exception handlers.
    ThrowSome code must throw an exception before you can Catch an exception. Regardless of what code throws the exception, it always involves the Throw statement.
    CatchWhen there is any issue occurred during the execution of the Try block, Katalon Studio executes all steps within.
    FinallyThis is the last part of the Try-Catch-Finally

In Script view

The Script view of test cases allows you to programmatically define and handle exceptions using Groovy or Java language. For more details about exception handling in Groovy, refer to this Groovy documentation: Try - Catch - Finally.

For example:

   try {


if (WebUI.getText(findTestObject('Object Repository/txt_singin')).length() < 0) {
throw new com.kms.katalon.core.exception.StepFailedException('Value required')
catch (StepErrorException e) {
catch (Exception e) {
this.println("General issue occurs.")
finally {
this.println("Navigate to a page.")
