It is usually not easy to start with automatic testing of an existing web application. You may have heard that applications must be written to be “testable”. But what if you still want the confidence that your refactoring did not cause the application to crash? And even if your application is testable that does not stop you or other people from skipping writing tests in order to “save” some time because let’s face it - the application can be used even without automatic tests. I will present to you our package for HTTP smoke testing that: - makes it easy to start with testing any Symfony web application - will automatically prompt you to test new pages/actions - is so cheap to use that you will not even think about skipping writing tests

6. Do you really test your code?

7. What is Smoke Testing?

8. When you’re testing a new electrical
device, plug it in and look for smoke

9. Smoke testing = Sanity check

10. HTTP Smoke Testing

13. shopsys / http-smoke-testing

14. The Good and the Bad

15. ✔ Little configuration needed

16. ✔ Tests all new routes automatically

17. ✔ Can have multiple scenarios per route

18. ✔ Works well even for hard-to-test apps

19. ✔ Good addition to classic test suites

20. ✘ Checks HTTP response codes only

21. ✘ Makes real requests

22. ✘ Needs demo data to work well

23. Let’s take a look!

24. How is it used
in Shopsys Framework?

25. Unit Testing
Integration / Database Testing
HTTP Smoke Testing
End-to-End Acceptance Testing
Nightly Performance Tests

26. Demo data set included
used for both development and tests

27. Automated via Phing
we can run “phing tests” to run them all or “phing tests-smoke” if we’re picky

28. HTTP Smoke Tests run in transactions
our PostgreSQL database is rolled back to its previous state after each one

29. Coupled with shopsys/coding-standards
can check coding standards and fix violations automatically

30. All checks are run on our CI server
don’t make your developers run tests, execute them automatically

31. Try it yourself!
