Value (feature spec)
❖ Only way to automatically ensure your application works for real users, since they use the application through the web browser, like real users.
❖ low coupling to the actual source code (black box test). This enables large refactorings. Rails version upgrade without tests, anyone?
❖ serve as application specification if written correctly.
![Page 15: Making feature specs fun again](https://reader035.vdocument.in/reader035/viewer/2022062600/58a7c6f41a28ab6b5a8b5a2b/html5/thumbnails/15.jpg)
Learning
❖ feature specs are more complex but more valuable than unit type tests.
❖ expect more effort to write & tame them.
![Page 16: Making feature specs fun again](https://reader035.vdocument.in/reader035/viewer/2022062600/58a7c6f41a28ab6b5a8b5a2b/html5/thumbnails/16.jpg)
#2: Tools. Use them.
![Page 17: Making feature specs fun again](https://reader035.vdocument.in/reader035/viewer/2022062600/58a7c6f41a28ab6b5a8b5a2b/html5/thumbnails/17.jpg)
The »old« way❖ several factories in each spec to set up test data
❖ CSS selectors inline in spec
❖ global, custom helper methods (#fill_form, anyone?)
❖ some custom RSpec matchers
❖ one assertion per test (being a good TDD citizen)
❖ many tests in one spec file
❖ sleep …
![Page 18: Making feature specs fun again](https://reader035.vdocument.in/reader035/viewer/2022062600/58a7c6f41a28ab6b5a8b5a2b/html5/thumbnails/18.jpg)
Pain points
❖ maintainability: duplication of CSS selectors, test setup no order to test files & helper code
❖ test stability: test sometimes fails even though feature OK
❖ runtime: test suite takes a long time to complete
❖ => slow to write, hard to debug & maintain

»Object graph« factories
❖ one-liner to create all test data

Questions to ask
❖ what is the system under test?
❖ which features do I care most about? (login, registration, payment)
❖ which scenarios are most important? (»happy path«)
❖ what is likely to break?

Take shortcuts
❖ Stub APIs (vcr gem)
❖ login »backdoor«
❖ don’t navigate to pages
❖ don’t assert every detail of a page
❖ a hackish test is always better than no test at all
