                     Tamás Árpád
•   PHP
•   ASP, SQL Server
•   Rendszerszervező – tervező
•   .Net, SQL Server
•   Módszertanok
Amiről szó lesz…
• Követelmények
  feltárása, explicitté, egyértelművé tétele
• Automatizált ellenőrzés
Probléma
A ló túloldala…
Egy megoldás: BDD
• Behavior Driven Development
 ▫ Specification-by-example
 ▫ Executable specification
BDD
• TDD – Test Driven Development


                           Red

             Refactor             Green
TDD – kicsit másképp
• TDD - Osztályok, kis egységek szintje
 ▫ „Ha a CSVFileReader osztály egy hibás dátumot
   tartalmazó sort olvas be, akkor dob egy
   InvalitDateFormat kivételt”
• BDD – üzleti nyelv – nagyobb egységek
 ▫ „Ha beimportáltatok egy hibás dátumot tartalmazó
   számlatörténetet, akkor hibaüzenetet kapok
   arról, hogy hibás dátumot tartalmaz az állomány”
Elfogadási teszt
                                             UI
Haladási irány                          Service
• TDD – ?
• BDD – kívülről befelé                 Domain
 1. Elfogadási teszt –
    használná a UI-t
 2. UI – meghívná Service-t
 3. Service – használná a Domain-t
 4. Domain osztály hivatkozik egy másik domain
    osztályra
Specifikáció formája
• User Story
 ▫ Cím:
    Kosár
 ▫ Ki-Mit-Miért csinál
    Potenciális vásárlóként
     szeretnék könyveket rakni a kosaramba
     azért, hogy egyszerre több könyvet meg tudjak
     rendelni
Specifikáció formája – Szcenáriók
• Sablon: Given – When – Then
• Scenario: Books should be placed into basket
 ▫   Given I have a basket with: Book1
 ▫   When I place Book2 into the basket
 ▫   Then my shopping cart should contain 2 items
 ▫   And my basket should contain exactly 1 Book1
 ▫   And my basket should contain exactly 1 Book2
