Hi all, I will try to keep this as brief as possible. With as much detail as I can. **Scenario** I am running a very simple test suite that will check multiple URL’s. Some of these URL’s have a prefix of https, others have a prefix of www. They all lead to the same site but I need to test that the sites are all up and running. Currently, I have it set like this; WebUI.openBrowser(’’) WebUI.maximizeWindow() WebUI.navigateToUrl(‘[https://website.com](https://website.com)’) CheckDefaultLanguage = WebUI.waitForElementAttributeValue(findTestObject(‘Check For English/Language\_Select’), ‘Value’, ‘English’, 3) if (CheckDefaultLanguage == false) { WebUI.click(findTestObject(‘Check For English/input\_ddlLanguage’)) ``` WebUI.click(findTestObject('Check For English/td_English')) ``` } WebUI.verifyTextPresent(‘Business Management Centre’, true) WebUI.navigateToUrl(‘[http://website.com](http://website.com)’) CheckDefaultLanguage = WebUI.waitForElementAttributeValue(findTestObject(‘Check For English/Language\_Select’), ‘Value’, ‘English’, 3) if (CheckDefaultLanguage == false) { WebUI.click(findTestObject(‘Check For English/input\_ddlLanguage’)) ``` WebUI.click(findTestObject('Check For English/td_English')) ``` } WebUI.verifyTextPresent(‘Business Management Centre’, true) WebUI.navigateToUrl(‘[http://www.website.com](http://www.website.com)’) CheckDefaultLanguage = WebUI.waitForElementAttributeValue(findTestObject(‘Check For English/Language\_Select’), ‘Value’, ‘English’, 3) if (CheckDefaultLanguage == false) { WebUI.click(findTestObject(‘Check For English/input\_ddlLanguage’)) ``` WebUI.click(findTestObject('Check For English/td_English')) ``` } WebUI.verifyTextPresent(‘Business Management Centre’, true) WebUI.closeBrowser() However, it has come to my attention that the above is a very set way of dealing with this and we are looking to move our servers to the cloud, therefore, this test needs to be used more. **Requirement** I need to make it so that, either in the test case or test suite, the prefix to the URL (www. or https etc.), is changed 4 times before moving on to the next case, or closing the browser. Is there any way of getting Katalon to run through multiple variables, through something like a data file? I just want to try and make this test as flexible as possible. Any questions please ask. **TL;DR:** I want a variable that changes 4 times before the test case finishes, changing the start of a URL each time. ---

Hey Josh, this is what I would do: ```auto import com.kms.katalon.core.configuration.RunConfigurationimport com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUIimport static com.kms.katalon.core.testobject.ObjectRepository.findTestObjectBufferedReader fr = new BufferedReader(new FileReader(RunConfiguration.getProjectDir() + "\\Data Files\\prefixes.txt"))List prefixes = new ArrayList<>()while((line = fr.readLine()) != null) { prefixes.add(line)}for(String prefix in prefixes) { WebUI.navigateToUrl(prefix + 'website.com') CheckDefaultLanguage = WebUI.waitForElementAttributeValue(findTestObject('Check For English/Language_Select'), 'Value', 'English', 3) if (CheckDefaultLanguage == false) { WebUI.click(findTestObject('Check For English/input_ddlLanguage')) WebUI.click(findTestObject('Check For English/td_English')) } WebUI.verifyTextPresent('Business Management Centre', true)} ``` First, put your prefixes into some file (I put it into /Data Files/prefixes.txt) - attached. Then, read all lines and put it into a list to work with them easily. Finally, use for-each loop to loop through all your prefixes and do the rest of stuff. The advantage of this solution is that your prefixes are centralized in a file - and you can use them in multiple test cases. Yes, you can simply create a list and put all prefixes there, but when you add/remove some of them, you’d have to rewrite all tests where the ya re included. This is more robust solution.

Marek, Thank you so much, that one was getting to me. ---

This is more robust solution. Mantra! Marek, please, write this up as a “Tip” so we can have it republished properly.
