Add a web elements to a ArrayList-CodePudding

i have a method in which I am trying to add 12 web elements:

private List<WebElement> iphoneSnippetList = new ArrayList<>();
@Test
public void test(){

    chromeDriver.get("https://market.yandex.ru/catalog--smartfony/54726/list?hid=91491&glfilter=7893318:153043&onstock=1&local-offers-first=0");

        new WebDriverWait(chromeDriver, 15).until(ExpectedConditions.elementToBeClickable(By.xpath("//article[@data-autotest-id='product-snippet'][1]")));

        for (int i = 0; i <= 12; i  ) {
            iphoneSnippetList.add((WebElement) By.xpath("//article[@data-autotest-id='product-snippet']["   i   "]"));
        }
        System.out.println(iphoneSnippetList);
    }

Simplified DOM elements in which I only need to get the text :

<article class="_2vCnw cia-vs cia-cs" data-autotest-id="product-snippet"</article>
<article class="_2vCnw cia-vs cia-cs" data-autotest-id="product-snippet"</article>
<article class="_2vCnw cia-vs cia-cs" data-autotest-id="product-snippet"</article>

I need to add all 12 web elements to my array and then make sure that the received elements contain the name "Iphone", but when adding elements, there is exception:

java.lang.ClassCastException: class org.openqa.selenium.By$ByXPath cannot be cast to class org.openqa.selenium.WebElement (org.openqa.selenium.By$ByXPath and org.openqa.selenium.WebElement are in unnamed module of loader 'app')

CodePudding user response：

iphoneSnippetList is a List of WebElement in Java-Selenium bindings.

I am not sure why you want to add 12 web elements using the loop, instead a findElements with right xpath would have been a good choice. Anyway, there's a problem with you code related to casting.

See below, driver.findElement will return the web element, and we are storing that into a variable called Webelement e, and adding the same into iphoneSnippetList

for (int i = 0; i <= 12; i  ) {
    WebElement e = driver.findElement(By.xpath("//article[@data-autotest-id='product-snippet']["   i   "]"));
    iphoneSnippetList.add(e);
}
    System.out.println(iphoneSnippetList);

Also, this loop will run for 13 times not 12 times. In case you want this to run for 12 times, initialize i = 1 not i = 0

I think you will have issue with xpath also, cause you are not using xpath indexing correctly.

try this instead :

for (int i = 1; i <= 12; i  ) {
     WebElement e = driver.findElement(By.xpath("(//article[@data-autotest-id='product-snippet'])['"  i  "']"));
     iphoneSnippetList.add(e);
}
System.out.println(iphoneSnippetList);
