Переключите pageLoadStrategy с нетерпеливого на обычный для существующего драйвера

Я установил pageLoadStrategy как eager, но теперь метод, который я написал для закрытия всплывающих окон веб-сайта, не работает (он работает, когда pageLoadStrategy равно normal). Итак, Я хочу знать, как изменить pageLoadStrategy с eager на normal, закрыть всплывающие окна, а затем изменить его на eager Я хочу использовать eager так, как хочу Мой код для работы также на низкоскоростных соединениях.

вот содержимое страницы, взятой driver.page_source, когда для pageLoadStrategy установлено значение eager:

это часть содержимого страницы (которое я хочу) в тот же момент, когда pageLoadStrategy установлен на normal:

Вы должны рассмотреть несколько вещей следующим образом:

  • Когда вы устанавливаете pageLoadStrategy как eager до DesiredCapabilities() эта конфигурация запекается в исполняемый файл chromedriver и сохраняется до времени жизни экземпляра WebDriver . Таким образом, вы не можете изменить pageLoadStrategy ни с eager на normal, ни наоборот, пока выполняется тест В процессе .

  • Вы можете найти пару соответствующих обсуждений в:

  • Сравнение Page Source , полученного с помощью варианта WebDriver с использованием обоих pageLoadStrategies you будет наблюдать:

    • Источник страницы с pageLoadStrategy как eager не содержит jQuery и AJAX cals: 

      <script src="/Scripts/jquery.2.1.1.min.js">
</script>
<script src="/Scripts/jquery.unobtrusive-ajax.min.js">
</script>

    • Следовательно, существует более высокая вероятность того, что вариант WebDriver будет пытаться взаимодействовать, например, click() , send_keys() даже до того, как JavaScript зарегистрирует различные HTML события DOM например, обработчики событий, для элементов с HTML документ, который в итоге приведет к click() сбоям .

Это точная причина всплывающего окна ... not закрываясь ... .

Решение

Из источника страницы с pageLoadStrategy как нетерпеливым , это Совершенно очевидно, что элементы на веб-странице - это элементы с поддержкой JavaScript, поэтому лучше использовать pageLoadStrategy как normal при выполнении теста.
