This presentation discusses using Selenium Grid and Docker for continuous delivery and automated testing. It outlines the benefits of continuous delivery such as reduced deployment risk and early bug detection. The presentation then describes using Selenium Grid to run tests across different browsers and machines simultaneously to save time. Docker is discussed as being secure, scalable, and flexible. The solution presented uses Selenium Grid in Docker containers to run a large test suite for multiple products with a small team. Metrics show increased reliability, scheduled test runs, and the ability to write tests in different frameworks. The future plans include moving the grid to an Azure swarm cluster and improving mobile emulation.

Our Problem
Run large test suites for multiple products as part of our
continuous integration process with a very small number of
QA Analysts and addressing all the security concerns.

8. Selenium Grid
• Run your tests against different
browsers, operating systems, and
machines all at the same time.
• Save time in the execution of your test
suite.

9. Selenium Grid

10. Docker
• Secure by default.
• Build for scale.
• Extensible and flexible.

13. The Results

14. Compose File

15. Some Scripts
• Application Up
• docker-compose docker-compose.yml –project-name mirage up -d
• Scale application
• docker-compose docker-compose.yml –project-name mirage scale firefox=50
chrome=50
• Application Down
• docker-compose docker-compose.yml –project-name mirage down -d

16. Some Code
• Selenium
• <add key="hubUrl" value="http://10.202.10.186:4445/wd/hub" />
• var driver = new RemoteWebDriver(hubUrl, desiredCapabilities);
• driver.FindElement(By.Id(”myId"));
• Protractor
• exports.config = { framework: 'jasmine', seleniumAddress: params.hubUrl}
• element(by.name('username'))

18. Our Future
• Move Grid to Swarm Cluster in Azure.
• Docker Container for IE.
• Improve Mobile Emulation.
