8. MILAN november 28th/29th 2014 “potresti farmi qualche esempio ?”
9. Esempi non test
10. public function testSomma(){ //... }
11. /** @test */
 function la_somma_dovrebbe_sommare_due_numeri(){ //... }
12. Linguaggio condiviso

24. Obiettivo (SMART)
25. I want an online conference planner system to sell to conferences’s organizers, which allows attendees to schedule their favorite talks. My first/pilot customer is “Agile conference”. I’ll sell conference planner to them with discount, so that they’ll test my software.
26. Features Gherkin
27. Gli strumenti che permettono di raggiungere l’obiettivo
28. Feature: Create personal scheduler In order to spend more time socialising at the conference instead of looking at the schedule As a conference attendee I want to create my personal schedule beforehand
29. Esempi Gherkin
30. Descrive come l’utente utilizza la feature
31. Scenario: Successfully selecting 1 talk Given there is a conference "XP Conference” And there is a "Specification" talk in first time period When I open the "/conferences/xp" page And I click "Add to my schedule" inside ".talk:contains('Specification')" block Then I should see ".talk:contains('Specification')" inside ".personal-‐schedule" block
32. Scenario: Successfully selecting 1 talk Given there is a conference "XP Conference” And there is a "Specification" talk in first time period When I open the "/conferences/xp" page And I click "Add to my schedule" inside ".talk:contains('Specification')" block Then I should see ".talk:contains('Specification')" inside ".personal-‐schedule" block accoppiati alla UI!!
33. Scenario: Successfully selecting 1 talk Given there is a conference "XP Conference” And there is a "Specification" talk in first time period When I open the "/conferences/xp" page And I click "Add to my schedule" inside ".talk:contains('Specification')" block Then I should see ".talk:contains('Specification')" inside ".personal-‐schedule" block HTML, HTTP ?
34. Scenario: Successfully selecting 1 talk Given there is a conference "Agile Conference” And there is a "Specification" talk in the first time period When I choose the "Specification" talk Then the "Specification" talk should be in my personal schedule
35. Scenario: Successfully selecting 1 talk Given there is a conference "Agile Conference” And there is a "Specification" talk in the first time period When I choose the "Specification" talk Then the "Specification" talk should be in my personal schedule cosa significa time period?
36. Scenario: Successfully selecting 1 talk from the 1 track conference for a single slot
 Given a conference named "Agile Conference" with 1 track
 And the "Specification" talk is scheduled for "10:30-11:30" slot on the conference track 1
 When I choose the "Specification" talk for my personal schedule of this conference
 Then the chosen talk for "10:30-11:30" slot of my schedule should be the "Specification" linguaggio condiviso (UL)
37. ++ conoscenza del dominio - - sprechi
38. non abbiamo scritto codice!
39. abbiamo un modello del nostro dominio ovvero lo scenario
40. Specifiche eseguibili
41. /**
 * @Given a conference named :name with :count track
 */
 public function aConferenceNamedWithTrack($name, $count)
 {
 
 }
42. /**
 * @Given a conference named :name with :count track
 */
 public function aConferenceNamedWithTrack($name, $count)
 {
 $conference =
 }
43. /**
 * @Given a conference named :name with :count track */
 public function aConferenceNamedWithTrack($name, $count)
 {
 $conference = Conference::namedWithTracks($name, $count);
 }

54. Comprensibile anche per non tecnici
55. Compilabile Non obsoleta
56. Alibi
