Why list is required just to cancel single pop up in selenium webdriver?

Question

In Page Object factory:

By popup=By.xpath("//button[test()='NO THANKS']");

public List<WebElement> getPopUpSize(){
return driver.findElements(popup);
}

public WebElement getPopUp(){
return driver.findElement(popup);
}

Calling above methods into Testcase:

LandingPage l = new LandingPage(driver);
if(l.getPopUpSize().size()>0)
{
l.getPopUp().click();
}

I didn't understand why do we have to create a list just to cancel single pop up?

Answer 1

No, you do not need findElements for a single web element. Use findElement instead or Explicit waits as illustrated below:

1. Using ExplicitWaits

Code:

public WebElement getPopUpWebElement(){
    return driver.findElement(popup);
}

and in test method:

    try {
        WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(30));
        wait.until(ExpectedConditions.elementToBeClickable(getPopUpWebElement())).click();
    }
    catch(Exception e){
        System.out.println("Could not click on pop up");
        e.printStackTrace();
    }
