Test on Rails based on “Rails Test Prescriptions” by Noel
Rappin Ryo Nakamura (@r7kamura) ✘ ╹◡╹ ✘
1. Why test? 2. Unit 3. Model 4. Functional 5.
View 6. Integration
Why test?
* to speed up validation * to design architectures *
to assure its quality ... Why test?
to speed up validation automating test * open browser... *
type the URL “h..tt..p://...” * check the contents...
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)
to assure its quality * prevent code from enbugging *
maybe forced to write test ... ;(
For more details why you... Please ask Mohicans around you
Unit Test
Forms of writing unit test - ✘╹◡╹ ✘ http://r7kamura.hatenablog.com/ entry/2012/09/19/113239
Unit Test
Model Test
Unit Test of Model. It's easy to write Model Test.
"Skinny Controller, Fat Model" Model Test
Functional Test
Functional tests Verify the system satisfies requested features of user.
In Rails, it tests Controller & View by 1 request
Targets 1. normal 2. invalid 3. security
1. normal A normal request should pass expected data to
the view. @foo, sessions, cookies, flash
2. invalid An invalid request should be handled properly. redirect_to
:root
3. security User’s and system’s security should be protected. get(others_entry_path).
should_not be_success
Non targets * many redirections * user interaction * HTTP
methods (in Rails)
View Test
View Test Verify: * logic * structure (semantic mean) Used
in Controller & Integration Test on Rails
Good targets * logic in a view (necessary evil...;) *
security problem * way to render structures
Bad targets * text in HTML tag * look and
feel verify only “semantic meanings”
Integration Test
Integration Test verify the interactions(I/F) of multiple components Acceptance test
might see to this. Capybara, Cucumber, ...
When to use Integration Test? To validate the interactions of
the modules that are well-tested.
Good targets * interactions in multiple steps * dependency with
prev state * legacy code (black-box) * with JavaScript
Bad targets * only 1 request * only for view
