Testing with Jenkins, Selenium and Continuous Deployment
23 likes15,239 views
This document discusses using Jenkins, Selenium and continuous deployment for testing web applications. It proposes using Jenkins for continuous integration, running Selenium tests on Amazon AWS instances through a Selenium Grid. A deployment tool is suggested to deploy any version of the code within an isolated environment using tools like Fabric, Gunicorn and Nginx. The solution allows running tests periodically, executing them in parallel on different browsers and providing live URLs of branches for QA testing.

Testing with Jenkins, Selenium and Continuous Deployment
- 1. Testing with Jenkins, Selenium and Continuous Deployment Max Klymyshyn oDesk PS Twitter: @maxmaxmaxmax Github: joymax
- 2. The problem We need to run our tests periodically Tests execution take a lot of time, it’s not an option to run on integrator’s machine all the time We want to run our Selenium tests on separated branches We don’t have persistent Selenium Grid nodes Blah blah, the CI problem...
- 3. The solution Jenkins as Continuous Integration tool Selenium Grid + Tests execution service with Amazon AWS instances on-demand Deployment tool which can deploy any version of the code within isolated environment
- 4. TOC Jenkins configuration Selenium Grid and Amazon AWS architecture Deployment tool with Fabric, Gunicorn, Nginx (+ Celery, Redis and Solr) Shortcuts for developers A bit about libraries development
- 6. Jenkins Coverage Tests results trend (junit reports) JSLint Pylint
- 7. Tests execution unit, integration, consistency tests with Nose Lettuce for forms and overall site UX JavaScript tests with Rhino and Flask-Jasmine Selenium UI tests
- 8. Selenium Tests Execute tests Start selenium node(s) with requested browser(s) Execute selenium tests Shutdown node
- 9. Selenium Tests and Jenkins Headless tests (pass) Deploy current commit Execute selenium tests Destroy deployed commit
- 10. on-demand selenium nodes Tests runner IE9 / Win IE8 / Win IE7 / Win Service FF / Win Chrome / Win FF / Linux Selenium Grid 2 Chrome / Linux
- 11. Selenium tests during dev Developer execute tests with specific browser It’s not necessary to have browser It’s possible to debug tests with IPDB It’s possible to see what’s going on on remove node using Selenium Node admin or making screenshots

- 14. Tests execution # Execute selenium tests in all browsers uitestrunner -c browsers.cfg -a # Execute synchronously in IE9 (+IPDB) uitestrunner -c browsers.cfg -s -b internetexplorer-9 # Execute one test $ uitestrunner -c browsers.cfg -b internetexplorer-9 -t
- 15. Deployment tool FTW Get commit or branch Create virtualenv Add Solr core install requirements Create mongo DB gunicorn by template Generate local_settings celery by template start services nginx by template
- 16. The flow for developers The problem: QA engineer should check quality of each issue/branch Developer should provide “live” url to its branch Solution: Deploy specific branch Provide URL to it to QA engineer
- 17. Shortcuts for developers Execute shortcuts in working branch: doit deploy doit destroy doit restart doit cleanup_build
- 18. Summary Easy-to-demonstrate new changes Easy to QA All team members informed about status
- 19. Questions?
