2. 1. Why test? 2. Unit 3. Model 4. Functional 5.

   View 6. Integration

3. Why test?

4. * to speed up validation * to design architectures *

   to assure its quality ... Why test?

5. to speed up validation automating test * open browser... *

   type the URL “h..tt..p://...” * check the contents...

6. to design architecture * write clean and independent code (test

   behaves like a third-party code) * think the correct behavior of code (this would be an example of test)

7. to assure its quality * prevent code from enbugging *

   maybe forced to write test ... ;(

8. For more details why you... Please ask Mohicans around you

9. Unit Test

10. Forms of writing unit test - ✘╹◡╹ ✘ http://r7kamura.hatenablog.com/ entry/2012/09/19/113239

    Unit Test

11. Model Test

12. Unit Test of Model. It's easy to write Model Test.

    "Skinny Controller, Fat Model" Model Test

13. Functional Test

14. Functional tests Verify the system satisfies requested features of user.

    In Rails, it tests Controller & View by 1 request

15. Targets 1. normal 2. invalid 3. security

16. 1. normal A normal request should pass expected data to

    the view. @foo, sessions, cookies, flash

17. 2. invalid An invalid request should be handled properly. redirect_to

    :root

18. 3. security User’s and system’s security should be protected. get(others_entry_path).

    should_not be_success

19. Non targets * many redirections * user interaction * HTTP

    methods (in Rails)

20. View Test

21. View Test Verify: * logic * structure (semantic mean) Used

    in Controller & Integration Test on Rails

22. Good targets * logic in a view (necessary evil...;) *

    security problem * way to render structures

23. Bad targets * text in HTML tag * look and

    feel verify only “semantic meanings”

24. Integration Test

25. Integration Test verify the interactions(I/F) of multiple components Acceptance test

    might see to this. Capybara, Cucumber, ...

26. When to use Integration Test? To validate the interactions of

    the modules that are well-tested.

27. Good targets * interactions in multiple steps * dependency with

    prev state * legacy code (black-box) * with JavaScript

28. Bad targets * only 1 request * only for view

    testing
