How to generate random Test Data with Katalon Studio?

Integrating the Test Data Builder with Katalon Studio is simple. Just follow these steps:

Install the Katalon Test Data Builder Plugin

Download the plugin from the Katalon Store.

Alternatively, get it offline from the ChangeLog.

Open the Data Builder UI

Click the DataBuilder icon to access the Data Builder interface.

Enter Values in the Form

Complete fields like File Name, Variable Name, and Count.

Create the Table

Click Create Table and fill in Headers and Sample Values (refer to Sample Data Format instructions for details).

Generate Data

Click Generate Data to populate your Katalon Data file with the generated values.

Use the Generated Data

The generated values are ready for use as variables for data binding in your tests.

Examples for Generating Different Random Values:

Full Name: 'Mohit{123}'

Output: Mohit432

Note: Values within {} are generated randomly.

Phone Number: '+94{56823512}'

Output: +9470294386 (with random 8-digit number after +94)

Start Date: '2025/{1::6}/{1::15}'

Output: 2025/5/5

Note: {1::6} generates a number between 1 and 6.

End Date: '2025-{6::12}-{16::31}'

Output: 2025-11-25

Date and Time: '202405{1::30}:{1::12}{1::30}33'

Output: 20240528:62820

Email Address: '{Mohit}{123}@gmail.com'

Output: Omoho718@gmail.com

Custom String: '{Mohit}{123}IRE{20345}STR-{1230}{MT}01STR{2025}'

Output: Toiio315IRE69027STR-7185MM01STR8107

These examples demonstrate how to leverage the plugin to generate custom, random data patterns for testing. The {} syntax allows you to specify custom patterns and ranges for random numbers, characters, or sequences.
