Test Data Generator Keywords

The Test Data Generator Plugin provides two primary keywords to help you efficiently manage your test data.

Generating a Random Value

To generate a random value, use the following keyword:

    CustomKeywords.'com.katalon.data.Generator.getRandomValue'(String sampleTestData)
    Exp:
    CustomKeywords.'com.katalon.data.Generator.getRandomValue'('Password@{123456}')

Saving a Random Value to an InternalData File

To save the generated random value into an InternalData File(User need to prepare Internal Data File with Columns), use the following keyword:

    CustomKeywords.'com.katalon.data.Generator.updateDataFile'(String dataFilePath, columsValues)
    Exp:
    CustomKeywords.'com.katalon.data.Generator.updateDataFile'('Data Files/LoginTestData', username + " " + password)

Below are some examples that demonstrate how to generate different types of random values:

Full Name:

fullName = CustomKeywords.'com.katalon.data.Generator.getRandomValue'('Mohit{123}')
Output: Mohit432
Note: Anything within {} is generated randomly.

Phone Number:

phone = CustomKeywords.'com.katalon.data.Generator.getRandomValue'('94{56823512}')
Output: 9470294386 (94 followed by an eight-digit random number)

Start Date:

startDate = CustomKeywords.'com.katalon.data.Generator.getRandomValue'('2025/{1::6}/{1::15}')
Output: 2025/5/5
Note: {1::6} generates a random number between 1-6.

End Date:

endDate = CustomKeywords.'com.katalon.data.Generator.getRandomValue'('2025-{6::12}-{16::31}')
Output: 2025-11-25

Date and Time:

dateTime = CustomKeywords.'com.katalon.data.Generator.getRandomValue'('202405{1::30}:{1::12}{1::30}33')

Custom String:

custom = CustomKeywords.'com.katalon.data.Generator.getRandomValue'('{Mohit}{123}IRE{20345}STR-{1230}{MT}01STR{2025}')
Output: Toiio315IRE69027STR-7185MM01STR8107

These examples demonstrate how to use the Test Data Generator Plugin to create a variety of random values for your test data. The syntax within the curly braces {} allows you to define patterns for generating random characters, numbers, or sequences.
