Types of Variables

Estimated reading time: 2 minutes

There are three types of variables supported in Katalon Studio, as below:

Groovy Variable

Test Case Variable

A Test Case Variable can be used to parameterize a test case or to call that test case with different inputs.

Global Variable (Execution Profiles)

A Global Variable can be accessed anywhere inside your project.

Refer to the subsequence sections for how to define a variable of each type.

Groovy Variables

For more details, please Groovy documentation. Examples:

// x is defined as a variable of String type
String x = "Hello";
// y is defined as a variable of int type
int y = 5;

// The value of the variables are printed to the console

Test Case Variables

You can manage Test Case Variable in the Variables tab of the Test Case Editor.

To add variable using grid view, switch to Variables tab of your Test Case. Then click Add. A new row is added to the variable list. Modify the variable details and save the test case once done.

Alternatively, variables can be added using Script Mode. Switch to Variable (Script Mode) tab, Katalon Studio will display a Script Editor with XML format. For example:

<?xml version="1.0" encoding="UTF-8"?>
<Entity xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="variableEntityWrapper">
      <defaultValue>'John Doe'</defaultValue>

Test Case Variables can be referred in test case as Groovy variables, e.g.

import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject

import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

import internal.GlobalVariable as GlobalVariable


WebUI.setText(findTestObject('Page_Login/txt_UserName'), Username)

WebUI.setText(findTestObject('Page_Login/txt_Password'), Password)


landingPage = WebUI.verifyElementPresent(findTestObject('Page_CuraAppointment/div_Appointment'), GlobalVariable.G_Timeout)

Test Case Variables can be utilized as parameters for the test case in other configurations. (e.g. input data for keywords in Manual View or params when binding Data for Test Execution).

For details on how to call test case with variables, refer to this article.
