The document explores Groovy and Spock frameworks, detailing their features, design goals, and integration within Java projects for testing. It provides examples of Groovy syntax, including array handling and basic test classes, as well as Spock specifications for behavior-driven development. Furthermore, it discusses Geb for browser testing, showcasing practical examples of web interactions and configurations for Maven integration.

given:
def a = 1
def b = 5
def c = 5
when:

then:

}

18. Beispiel: expect
class MathSpec extends spock.lang.Specification {
def Maximum von zwei nummerischen Werten() {
expect:
Math.max(1, 5) == 5
Math.max(2, 3) == 3
}
}

19. Beispiel: exception
class MathSpec extends spock.lang.Specification {
def Division durch 0 löst ArithmeticException aus() {
when:
1.0 / 0
then:
ArithmeticException e = thrown()
e.message =~ Division
}
}

20. Beispiel: data-driven

Math.max(value1, value2) == result
where:
value1 [1, 2, 3]
value2 [5, 3, 7]

def Maximum von zwei nummerischen Werten() {

25. Beispiel: Web 2.0 Taschenrechner

26. Beispiel - Scripting Ansatz
def Addition von zwei Zahlen() {
given:
go http://web2.0rechner.de/
expect:
title == Web 2.0 Taschenrechner
when:
$(a#num_1).click()
$(a#A42).click()
$(a#num_2).click()
$(a#btn_equal).click()
then:
$(input#input).value() == 3
}

27. Page-Object kapselt Seiten-Details
class TaschenrechnerPage extends Page {
static url = http://web2.0rechner.de/
static at = { title == Web 2.0 Taschenrechner }
static content = {
btn_1 { $(a#num_1) }
btn_2 { $(a#num_2) }
btn_add { $(a#A42) }
btn_equals { $(a#btn_equal) }
display { $(input#input) }
}
}
IUUQXXXHFCJTIPSHNBOVBMDVSSFOUQBHFTIUNMQBHFT

28. Beispiel - Page-Object Ansatz
def Addition von zwei Zahlen() {
given:
to TaschenrechnerPage
when:
btn_1.click()
btn_add.click()
btn_2.click()
btn_equals.click()
then:
display.value() == 3
}

29. Page-Object kapselt Funktionalität
class TaschenrechnerPage extends Page {
...
static content = {
btn { char c - $(a# + ids[c.toString()]) }
result { display.value() }
}
def ids = [
1 : num_1,
...
+ : A42,
= : btn_equal
]
def calculate( String formula ) {
formula.chars.each {
type it
}
type('=' as char)
}
def type( char character ) {
btn(character).click()
}
}

30. Beispiel - Funktionale Spezifikation
def Addition von zwei Zahlen() {
given:
to TaschenrechnerPage
when:
calculate(1+2)
then:
result == 3
}

31. Beispiel - Spock Data-Table
@Unroll(#formula ergibt #expectedResult)
def Addition von zwei Zahlen() {
given:
to TaschenrechnerPage
when:
calculate(formula)
then:
result == expectedResult
where:
formula | expectedResult
1+2 | 3
2+3 | 6
3+4 | 7
4+5 | 9
5+6 | 11
}
