BDD

With Spock

TDD를처음접할때고민

• http://dannorth.net/introducing-bdd/

TEST할때 5가지고민들

1. 어디서부터프로세스를시작해야되지?

2. 테스트여부를어떻게정하지?

3. 한번에얼만큼테스트해야되지?

4. 테스트를어떻게명명해야되지?

5. 테스트가실패하는이유를어떻게이해하지?

http://dannorth.net/introducing-bdd/

Behaviour DD

• 구체적으로의도를잘이해할수있도록시나리오를가지고명세화하자.

• 템플릿

1. Given ( 어떤값이할당되었을때 )

2. When ( 이벤트가발생했을때)

3. Then ( 결과는 ~ 여야한다.)

Mocking과는무슨차이?

• 이미쓰는데요expect( some.doing(ABC)).andReturn(True).times(2);

UML처럼개발자가아닌사람에게도

BDD in Action Manning

Spock

• Peter Niederwieser이 Groovy로만든 BDD 프레임워크

Spock 준비(Gradle)

Start

Import spock.lang.*

start2

명세작성

Class MyFirstSpecification extends Specification{

fields

fixture methods

feature methods

helper methods

}

example1

• class HelloSpockSpec extends spock.lang.Specification {

• def "length of Spock's and his friends' names"() {

• expect:

• name.size() == length

• where:

• name <<["kirk", "spock", "scotty"]

• length <<[4, 5, 7]

• }

시나리오시작

예상하는결과

Spock의 where절

• Given

• When,

• Then

• 표준템플릿유형이고반드시이유형으로작성해야하는것은아님

Spock의 where절의유형

• Spock의 where절은 2가지경우에사용

순회해야할요소를가지고있거나,

시나리오안에데이터테이블을가지고있을때

Spock where usage

where:

name <<["kirk",

"spock", "scotty"]

length <<[4, 5, 7]

where:

Name | gender

‘sara’ | ‘W’

‘mike’ | ‘m’

‘stacy’ | ‘w’

Namelength =name.length()
