int count = 0
price.each {
if (it > 299)
count++
}
if (count > 0) assert false, "Not all price is greater than 299"int count = 0
price.each {
if (it > 299)
count++
}
if (count > 0) assert false, "Not all price is greater than 299"What is it??? i cant understand what is the meaning on "it" in the context of groovy scripting

The piece of code is being "iterated" over the list and "it" is a reserved keyword and refers to the current element of the list during iteration.
Hi chathurad,
As nmrao said, 'Groovy' language is simple and groovy, you are able to take the better way to deal with your requirements. Groovy has many extended methods based on Java Class / method.
as for "it", a closure using an implicit parameter. you can also specify a parameter like {param -> xxxxx}
(Example)
for list, often using each / collect / any / every / find / findAll / eachWithIndex...etc
def alist = [100, 200, 300, 400, 500]
alist.each {
println(it) //output: 100, 200, 300, 400, 500
}
alist.each {element ->
println(element) //output: 100, 200, 300, 400, 500
}
def blist = alist.collect {
if (it > 300)
it
}
println(blist.findAll {it != null}) //output: [400, 500]
def clist = alist.find {
it > 300
}
println(clist) //output: 400
def dlist = alist.findAll {
it > 300
}
println(dlist) //output: [400, 500]
def t = alist.every {
it > 99
}
println(t) //output: true
def t2 = alist.any {
it > 400
}
println(t2) //output: true
alist.eachWithIndex {element, index ->
if (element > 300)
println("$index: $element") //output: 3: 400 / 4: 500
}
you would access official website: http://www.groovy-lang.org/single-page-documentation.html to understand more. and check API: http://www.groovy-lang.org/api.html to understand more usage based on language.
Thanks,
