Features, scenarios, and steps give the high-level limited-form natural-language definition of aspects of the user story.
Let's walk through some scenarios and think about what work we might have to do to implement these Cucumber scenarios. Do they effect model, view, or controller (or all three)? (Suppose we had the repaired version of the original database, with no director.)
Feature: search for movies by director As a movie buff So that I can find movies with my favorite director I want to include and search on director information in movies I enter Background: movies in database Given the following movies exist: | title | rating | director | release_date | | Star Wars | PG | George Lucas | 1977-05-25 | | Blade Runner | PG | Ridley Scott | 1982-06-25 | | Alien | R | | 1979-05-25 | | THX-1138 | R | George Lucas | 1971-03-11 | Scenario: add director to existing movie When I go to the edit page for "Alien" And I fill in "Director" with "Ridley Scott" And I press "Update Movie Info" Then the director of "Alien" should be "Ridley Scott" Scenario: find movie with same director Given I am on the details page for "Star Wars" When I follow "Find Movies With Same Director" Then I should be on the Similar Movies page for "Star Wars" And I should see "THX-1138" But I should not see "Blade Runner" Scenario: can't find similar movies if we don't know director (sad path) Given I am on the details page for "Alien" Then I should not see "Ridley Scott" When I follow "Find Movies With Same Director" Then I should be on the home page And I should see "'Alien' has no director info"
