As part of my regression testing I want to create multiple users/logins however the software I’m testing doesn’t allow duplicates, so as soon I have recorded the action of creating an user when trying to play back the test I’m getting a validation message due to the username already been used

Hi,

You will need some little tricks in using the unique username in your case. Just need to add a generation step for the username’s variable and it will be unique in every step.

Example:

> import static com.kms.katalon.core.checkpoint.CheckpointFactory.findCheckpoint  
> import static com.kms.katalon.core.testcase.TestCaseFactory.findTestCase  
> import static com.kms.katalon.core.testdata.TestDataFactory.findTestData  
> import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject  
> import com.kms.katalon.core.checkpoint.Checkpoint as Checkpoint  
> import com.kms.katalon.core.checkpoint.CheckpointFactory as CheckpointFactory  
> import com.kms.katalon.core.mobile.keyword.MobileBuiltInKeywords as MobileBuiltInKeywords  
> import com.kms.katalon.core.mobile.keyword.MobileBuiltInKeywords as Mobile  
> import com.kms.katalon.core.model.FailureHandling as FailureHandling  
> import com.kms.katalon.core.testcase.TestCase as TestCase  
> import com.kms.katalon.core.testcase.TestCaseFactory as TestCaseFactory  
> import com.kms.katalon.core.testdata.TestData as TestData  
> import com.kms.katalon.core.testdata.TestDataFactory as TestDataFactory  
> import com.kms.katalon.core.testobject.ObjectRepository as ObjectRepository  
> import com.kms.katalon.core.testobject.TestObject as TestObject  
> import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WSBuiltInKeywords  
> import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS  
> import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUiBuiltInKeywords  
> import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI  
> import internal.GlobalVariable as GlobalVariable  
> import org.apache.commons.lang.RandomStringUtils
> 
> ‘Max length of generated string’  
> randomStringLength = 5
> 
> String charset = ((‘a’…‘z’) + (‘A’…‘Z’) + (‘0’…‘9’)).join()  
> String randomString = RandomStringUtils.random(randomStringLength, charset.toCharArray())  
> userName = userName + randomString
> 
> WebUI.openBrowser(GlobalVariable.G\_SiteURL)  
> WebUI.setText(findTestObject(‘Page\_Login/txt\_UserName’), Username)  
> WebUI.closeBrowser()

P/s: In the further case that you need to execute test suite on multiple dataset, it’s best to use data-driven feature of the test suite:
