The document outlines strategies for automating functional tests in Django projects using Selenium, highlighting the importance of design patterns like PageObject and PageFactory to manage test execution times. It emphasizes setting up Selenium Grid for concurrent testing and recommends tools like pytest and Factory Boy for test data generation. Best practices include using explicit waits, employing helper methods, and integrating continuous testing and BDD tools.
PyCon Ukraine 2014
- 1. AUTOMATED FUNCTIONAL TESTS BASED ON SELENIUM FOR DJANGO PROJECTS ANDRII SOLDATENKO
- 2. ABOUT ME: • TEST AUTOMATION LEAD AT LUXOFT • PYTHON DEVELOPER AT TOPTAL • @A_SOLDATENKO • HTTP://ANDRIISOLDATENKO.GITHUB.IO/
- 3. “TESTS ARE THE PROGRAMMER’S STONE, TRANSMUTING FEAR INTO BOREDOM.” - KENT BECK 3 WE DON’T HAVE TIME FOR TESTS!
- 4. TEST AUTOMATION PYRAMID: Unit tests Integration tests Functional tests
- 5. TASK: HOW TO AUTOMATE FUNCTIONAL TESTS FOR WEB?
- 6. ABOUT SELENIUM: • PIP INSTALL -‐U SELENIUM • SELENIUM WEBDRIVER API NOW IN W3C DRAFT SPECIFICATION • RUN IN MANY BROWSERS • AND OS • CAN BE CONTROLLED BY DIFFERENT PROGRAMMING LANGUAGES
- 7. 7 DEMO
- 8. WHEN NUMBER OF TESTS IS GROWING: • WE NEED TO DECREASE TEST EXECUTION TIME • WE NEED TO USE DESIGN PATTERNS (I.E PAGEOBJECT, PAGEFACTORY) • WE NEED TO USE SKELETON FOR ORGANIZING TESTS
- 9. SKELETON FOR ORGANIZING TESTS:
- 10. DESIGN PATTERNS:
- 11. SIMPLE SELENIUM TEST WITHOUT PAGEOBJECT:
- 12. SIMPLE SELENIUM TEST WITH PAGEOBJECT:
- 13. SIMPLE SELENIUM TEST WITH PAGEOBJECT:
- 14. SIMPLE SELENIUM TEST WITH PAGEOBJECT:
- 15. WHAT ABOUT FT IN DJANGO?
- 16. HOW TO DECREASE TEST EXECUTION TIME ? • SET UP LOCAL SELENIUM GRID • USE SAUCE LABS • USE PYTEST OR NOSE
- 18. SETUP SELENIUM GRID LOCALLY:
- 19. SCHEME FOR SELENIUM GRID + CONCURRENT TEST EXECUTION py.test unittest.TestCase Node Node Node Hub
- 20. BEST PRACTICE FOR TEST DATA GENERATION AND • DJANGO LOREM IPSUM UTILS • DON’T USE FIXTURES • USE FACTORY BOY + FAKER INSTEAD OF FIXTURES
- 21. BEST PRACTICE FOR CREATION FT TESTS: • USE EXPLICIT WAITS RATHER THAN IMPLICIT WAITS. • USE CODE—HELPER METHODS IN BASE CLASS, OR PAGE PATTERN. • AVOID DOUBLE-‐TESTING FUNCTIONALITY • LOOK INTO BDD TOOLS • USE CONTINUOUS INTEGRATION
