Be flexible with zalenium, a dockerized selenium grid infrastructure
- 1. Be flexible with Zalenium, a dockerized Selenium Grid infrastructure George Romanas, Software Engineer in Test
- 2. What is Selenium Grid? 2 Selenium-Grid allows you run your tests on different machines against different browsers in parallel
- 3. When to use Selenium Grid? 3 ● To run your tests against multiple browsers, multiple versions of them, and browsers running on different operating systems. ● To reduce the time it takes for the test suite to complete a test pass
- 4. Common Selenium Grid issues 4 ● Keep up with the releases of the new Selenium versions and have them in synchronization with the browsers versions and releases and the browsers drivers releases. ● Spend time to maintain your own Selenium grid solutions ● Spend time trying to find out what caused an issue in the infrastructure.
- 5. You don’t want to end up like this !!!! 5
- 6. ● Dynamic Selenium Grid ● Based on docker Selenium ● Expands during run time ● Simple to setup ● Video recording ● Dashboard ● Live preview ● Interaction with the browser What is Zalenium? 6
- 7. ● Hard to maintain a stable Selenium Grid ● No more wasted hours trying to solve issues in the infrastructure ● Difficult to cover all needed capabilities ● Browsers versions are based in docker selenium image ● Anyone can have a disposable and flexible Selenium Grid infrastructure Why Zalenium? 7
