How to get the number of elements

How to get the number of elements,I remember selenium can use find_ elements

You can use the selenium method in KS, like.

List<WebElement> rows_table = Table.findElements(By.tagName('tr'));
numItems = rows_table.size();

or like:

List<WebElement> myList = WebUI.findWebElements(TestObject)
numItems = myList.size();

Also, if you are talking the number of Options in a drop-down list, then there is:

numItems =  WebUI.getNumberOfTotalOption(findTestObject('myPage/select_ProvinceState'));

or the number of selected Options:

numItems = WebUI.getNumberOfSelectedOption(findTestObject('myPage/select_ProvinceState'))

Hi 1968693027,

You can use the Katalon class WebUiCommonHelper… Follow the code below:

import com.kms.katalon.core.webui.common.WebUiCommonHelper
import org.openqa.selenium.WebElement

private void sampleMethod() {
		
		List<WebElement> elems = WebUiCommonHelper.findWebElements(findTestObject("Your_Object"), 30)
		
		println elems[0].getText()
		println elems.text
		println elems.size()
	}

Hope that helps. . . :smiley:

Do you know the reason for the failure
List elems = WebUiCommonHelper.findWebElements(findTestObject(‘Object Repository/Page_IO Controller WAN/Deploy/Underlay_Network/Wan_Interface/text_UnderlayWan_SDIp_Num’),30)

The error message states the cause for your MultipleCompilationErrorsException; you have already initiated (declared) a variable and you are doing it again (only declare a variable once within scope). To fix this error, leave the declaration of List, or List<WebElement>, on your first statement, but remove the declaration of List, or List<WebElement>, for the variable elems on all others and do not try to redeclare the same variable as something else, like a number or String.

As an example:


List<WebElement> elems = WebUiCommonHelper.findWebElements(findTestObject('Object Repository/Page_IO Controller WAN/Deploy/Underlay_Network/Wan_Interface/text_UnderlayWan_SDIp_Num'),30)
...
elems = WebUiCommonHelper.findWebElements(findTestObject('Object Repository/Page_IO Controller WAN/Deploy/Underlay_Network/Wan_Interface/text_SevenOaks'),30)
...
elems = WebUiCommonHelper.findWebElements(findTestObject('Object Repository/Page_IO Controller WAN/Deploy/Underlay_Network/Wan_Interface/text_DisneyWorld'),30)

Hi 1968693027,

findWebElements will return list(Array) items and in order to use the web element methods, you should include WebElement like this:

List<WebElement> elems = WebUiCommonHelper.findWebElements(findTestObject(‘Object Repository/Page_IO Controller WAN/Deploy/Underlay_Network/Wan_Interface/text_UnderlayWan_SDIp_Num’), 30)

But if you just need to locate one specific element using selenium approach and utilize the findTestObject of katalon at the same time then you can use this approach:

WebElement elem = WebUiCommonHelper.findWebElement(findTestObject(‘Object Repository/Page_IO Controller WAN/Deploy/Underlay_Network/Wan_Interface/text_UnderlayWan_SDIp_Num’), 30)

findWebElements if you want to get many objects and store it in an array.
findWebElement if you want to locate a specific object.

Hope that helps. . . :smiley:
