• BehaviorDrivenDevelopment

(In SoftwareEngineering) 행동중심개발. TestDrivenDevelopment의 변형.

10분 정도 살펴본 후 드는 생각:

• 대체적으로 훌륭하다.

• TestDrivenDevelopment의 Test는 Blackbox 혹은 Whitebox가 아니라 Graybox 테스트라는 말이 있다. 하지만 BehaviorDrivenDevelopment의 Behavior는 PsychologicalBehaviorism - Blackbox - 을 연상시킨다.

• MockObject framework의 사용을 장려하는 점.

Template:

<Story>:

• <Story Title>

• <Narrative>

  • As a <Role>

  • I want <Feature>

  • So that <Benefit>

• <Acceptance Criteria> - Set of <Scenario>s

  • <Scenario Title>

    • Given <Given>, and <Given>, ..., and <Given>

    • When <Event>

    • Then <Outcome>, and <Outcome>, ..., and <Outcome>

Example:

• Title: Customer withdraws cash
• Narrative
  • As a customer
  • I want to withdraw cash from an ATM,
  • So that I don't have to wait in line at the bank.
• Acceptance Criteria
  • Scenario 1: Account is in credit
    • Given the account is in credit, and the card is valid, and the dispenser contains cash
    • When the customer requests cash
    • Then ensure the account is debited, and ensure cash is dispensed, and ensure the card is returned

Code(그냥 한번...):

with(JSSpec.DSL) {

Epic('Account management')
  Given('The account', 'The credit card')

  Story('Customer withdraws cash')
    As_a('customer')
    I_want('to withdraw cash from an ATM')
    So_that('I don\'t have to wait in line at the bank')

    Scenario('Account is in credit')
      Given('The card is valid', 'The dispenser contains cash')
      When(function() {
        // event
      })
      Then(function() {
        // expected outcome
      })

    Scenario('Account is in credit')
      Given('The card is valid', 'The dispenser contains cash')
      When(function() {
        // event
      })
      Then(function() {
        // expected outcome
      })

  Story('Customer withdraws cash')
    As_a('customer')
    I_want('to withdraw cash from an ATM')
    So_that('I don\'t have to wait in line at the bank')

    Scenario('Account is in credit')
      Given('The card is valid', 'The dispenser contains cash')
      When(function() {
        // event
      })
      Then(function() {
        // expected outcome
      })

    Scenario('Account is in credit')
      Given('The card is valid', 'The dispenser contains cash')
      When(function() {
        // event
      })
      Then(function() {
        // expected outcome
      })
}
