Есть интеграционный тест на Selenium + PHPUnit:

<?php
namespace Site\Selenium\Test;

use Facebook\WebDriver\Exception\NoSuchElementException;

    use SiteTrait;

    /**

    public function testFilters()

        $chrome = self::getChrome();
        $chrome->manage()->deleteAllCookies();

        $news_url = self::getTargetUrl() . '/news/';
        $chrome->get($news_url);

        $newsHref = self::getNewsItems($chrome);

        // Дата
        self::openCalendar($chrome);

        $filterNewsHref = self::getNewsItems($chrome);

        assertTrue((array_diff($newsHref, $filterNewsHref)) ? true : false, 'Фильтр по дате не сработал');

        $typeItems = $chrome->findElements($typeItemsSelector);
        $typeItems[rand(0, count($typeItems) - 1)]->click();
        $filterNewsHref = self::getNewsItems($chrome);
        assertTrue((array_diff($filterNewsHref, $newsHref)) ? true : false, 'Фильтр по рубрике не сработал');
    }

    private static function getNewsItems(RemoteWebDriver $chrome): array

            foreach ($newsItems as $frch_item) {

            }
        }
        catch (NoSuchElementException $e) {

        return $newsHref;
    }

    private static function openCalendar($chrome) {

    private static function openPrevMount($chrome) {

        $calendarItems = $chrome->findElements($calendarItemsSelector);


        $calendarItems[rand(0, count($calendarItems) - 1)]->click();
    }
}

Если запускать только этот тест, то всё ok, он прекрасно работает, но вот если запустить все тесты, то он выдаёт ошибку:

1) Site\Selenium\Test\NewsFiltersTest::testFilters
Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session/43170fb6bd154f91bc8fb7c3d2694345/elements with params: {"using":"xpath","value":"//a[contains(@class, 'news-item')]"}

Элемента селектор котого фигурирует в тексте ошибки:

$newsItemsSelector = WebDriverBy::xpath("//a[contains(@class, 'news-item')]");

На странице может и не быть и тогда сработает цикл while, который будет работать пока не найдёт страницу на который элементы по селектору есть в наличии:

$newsItemsSelector = WebDriverBy::xpath("//a[contains(@class, 'news-item')]");
            $newsItems = $chrome->findElements($newsItemsSelector);

            while (count($newsItems) === 0) {
                self::openCalendar($chrome);
                self::openPrevMount($chrome);
                self::clickToRandomDate($chrome);
                $newsItems = $chrome->findElements($newsItemsSelector);
            }

Подскажите в чём дело?!? Почему этот код работает если запускать тест в одиночку и не работает при общем запуске тестов?!?
