Efficient Selenium Infrastructure with Selenoid

Feb 16, 2020. 10:00 - 18:00

Minsk, Renaissance Hotel

One of the top workshops from the group:


Selenoid is an alternative lightning fast open-source Selenium protocol implementation running browsers and Android emulators inside Docker containers. It is distributed with a set of ready-to-use Docker images corresponding to the majority of popular browser versions, has a one-command installation utility and works slightly more efficiently than traditional Selenium Grid.

This workshop shows how to build efficient and scalable browser automation infrastructure using Selenoid and related tools. You will be taught why running browsers in containers is so efficient, how to easily install Selenoid and use its powerful features.


Selenoid – это альтернативная молниеносно быстрая реализация протокола Selenium с открытым исходным кодом, запускающая браузеры и эмуляторы Android внутри контейнеров Docker. Он распространяется с набором готовых к использованию образов Docker, соответствующих большинству популярных версий браузера, имеет утилиту установки с одной командой и работает несколько эффективнее, чем традиционная Selenium Grid.

На этом мастер-классе (workshop) будет рассказано, как построить эффективную и масштабируемую инфраструктуру автоматизации браузера с помощью Selenoid и связанных с ним инструментов. Вы изучите почему запуск браузеров в контейнерах настолько эффективно, и как легко установить Selenoid и использовать его мощные функции.

Целевая аудитория:

  • Веб-разработчики
  • Инженеры по автоматизации тестирования

Вы научитесь:

  • Устанавливать и запускать Selenoid
  • Работать с базовыми функциями Selenoid
  • Создавать и сопровождать Selenoid кластер
  • Настраивать Ggr
  • Использовать продвинутые функции Selenoid для больших кластеров
