Не удается найти веб-элементы с Selenium, которые я вижу в окне просмотра браузера Chrome

Редактировать: Он работает с драйвером Chrome, но не с HtmlUnitDriver, почему?

Я пытаюсь получить WebElements с classname = "cat-pick_i"

Я вижу эти элементы в окне проверки Chrome, как показано здесь Inspect window output

Мой код выглядит следующим образом: 

WebDriver driver = new HtmlUnitDriver(true);

    driver.get("https://amzscout.net/sales-estimator");
    System.out.println("Title : "+driver.getTitle());

    WebElement pickList = driver.findElement(By.className("cat-pick_list"));
    System.out.println(pickList.toString());

    List<WebElement> elements = pickList.findElements(By.className("cat-pick_i"));
    System.out.println("num of categories : "+elements.size());

    for (int i = 0; i <elements.size() ; i++) {
        WebElement element = elements.get(i).findElement(By.className("cat-pick_name-in"));
        System.out.println(element.getText());
    }

И вывод моего кода такойследует, 

Title : Amazon Products Sales History Estimator, Rank Calculator | AMZScout
<div class="cat-pick_list" />
num of categories : 0

Process finished with exit code 0

Мой вопрос , почему я не могу получить эти WebElements и как я могу их получить.

Редактировать: Есть также предупреждения от HtmlUnitDriver , что может быть полезно

Или вы можете попробовать это напрямую: 

List<WebElement> elements = pickList.findElements(By.cssSelector(".container > .cat-pick_list > .cat-pick_i"));

Я думаю, что это должно работать.

Если быть более точным из ваших критериев поиска, есть два элемента div с именем класса: 'cat-pick_list', а второй пустой.

Примечание: начать использовать селекторы css и xpath (только если селектор css не помогает), лучшим вариантом будет id.

Попробуйте с 

WebElement pickList = driver.findElement(By.cssSelector(".container > .cat-pick_list"));
.....
List<WebElement> elements = pickList.findElements(By.cssSelector(".cat-pick_i"));
