Test Automation Architecture in Microservices
- 2. TESTING RELATED ISSUES IN MICROSERVICES Services are built and deployed independently Services talk to each other to accomplish things Builds and deploys are automated Data is not centralized Cross functionals need to be tested way before the end Tests need to be executed way earlier Tests need to be executed way later 2
- 3. THE INFAMOUS TEST AUTOMATION PYRAMIDE 3
- 6. SERVICES ARE BUILT AND DEPLOYED INDEPENDENTLY 6You can’t depend on other services to be up
- 7. SERVICES ARE BUILT AND DEPLOYED INDEPENDENTLY 7 Use test doubles to resolve your dependencies Mountebank
- 8. SERVICES ARE BUILT AND DEPLOYED INDEPENDENTLY 8 Your tests should be able to run in isolation Docker
- 9. SERVICES TALK TO EACH OTHER TO ACCOMPLISH THINGS 9Keep the communication between your services alive
- 10. SERVICES TALK TO EACH OTHER TO ACCOMPLISH THINGS 10 Create Consumer Driven Contract Tests between services Pact
- 11. BUILDS AND DEPLOYS ARE AUTOMATED 11You don’t have a buffer time between builds
- 12. BUILDS AND DEPLOYS ARE AUTOMATED 12 Multiple layers of testing Layered path to production deployment Blue - Green deployments Canary releases
- 13. BUILDS AND DEPLOYS ARE AUTOMATED 13 Repeatable environments Vagrant, Puppet, Chef, Ansible, Docker
- 14. DATA IS NOT CENTRALIZED 14 You have to manage each test data seperately Each test creates its own data
- 15. DATA IS NOT CENTRALIZED 15 Each test data should be unique accross the test suite Each test deletes only the data it created
- 16. CROSS FUNCTIONALS NEED TO BE TESTED WAY BEFORE THE END 16 Again, you can’t wait until everything is completed
- 17. CROSS FUNCTIONALS NEED TO BE TESTED WAY BEFORE THE END 17 Put in automated performance tests in your CDP Jmeter, Gattling, Locust
- 18. CROSS FUNCTIONALS NEED TO BE TESTED WAY BEFORE THE END 18 Put in automated security checks in your CDP OWASP ZAP, OWASP Dependency Check, W3af
- 19. TESTS NEED TO BE EXECUTED WAY EARLIER 19 Tests aren’t the responsibility of the testers alone You need to start testing right away
- 20. TESTS NEED TO BE EXECUTED WAY EARLIER 20 You should minimize testing things as a whole End to End (E2E) tests
- 21. TESTS NEED TO BE EXECUTED WAY EARLIER 21 Implement Journey Tests Selenium, Capybara, Sahi, Appium
- 22. TESTS NEED TO BE EXECUTED WAY LATER 22 See what’s going on in production Monitor things
- 23. TESTS NEED TO BE EXECUTED WAY LATER 23 Analyze trends and problems on production Have some tests which are run in production
- 24. TESTS NEED TO BE EXECUTED WAY LATER 24 Be a Quality Analyst
- 25. COMMON PITFALLS Don’t use a fixed recipe Build your architecture incrementally Keep your architecture alive 25
