Thread: GROOVY Script: List / Map Collection Problem

Firstly, I'm new to Groovy so apologies in advance for any school boy errors in the below.

I've created a script which I'm using to simulate the behaviour of a SOAP service in SOAP UI (as a mock service) for sprint testing purposes but am having problems when trying to iterate over a List I've created. The List is made up of a number of Maps, and each Map contains a List. It should look something like this:

[[Rec: 1, Items: ["AB123","BC234","CD345"]],[Rec: 2, Items: ["AB123","BC234","CD345","DE456"]]]

And this is the code I have to build up the List:

def offerMap      = [:] 
def outputList    = [] 
def offerItemList = [] 
 
def outputMap     = [:] 
def outList       = [] 
 
def item          = "" 
def rec           = "" 
 
offerItemList.add("AB123") 
offerItemList.add("BC234") 
offerItemList.add("CD345") 
 
offerMap.put("Rec",1) 
offerMap.put("Items",offerItemList) 
 
outputList.add(offerMap) 
 
log.info "OUT: outputList.size ${outputList.size()}" 
log.info "OUT: offerItemList.size ${offerItemList.size()}" 
 
offerMap.clear() 
offerItemList.clear() 
 
offerItemList.add("AB123") 
offerItemList.add("BC234") 
offerItemList.add("CD345") 
offerItemList.add("DE456") 
 
offerMap.put("Rec",2) 
offerMap.put("Items",offerItemList) 
 
outputList.add(offerMap) 
 
log.info "OUT: outputList.size ${outputList.size()}" 
log.info "OUT: offerItemList.size ${offerItemList.size()}"

And this is the the code I have to iterate over the list:

outputList.each { 
 
    log.info "OUT: outputList.size ${outputList.size()}" 
 
    outputMap.clear() 
    outputMap = it 
 
    row = outputMap.get("Rec") 
    log.info "OUT: REC ${rec}" 
 
    outList.clear() 
    outList = outputMap.get("Items") 
 
    outList.each { 
 
        item = it 
        log.info "OUT: Item ${item}" 
 
    } 
}

But this is not giving me the results I expect, first problem is that the .each loop for outputList appears to immediately be jumping to the second entry in the list, as witnessed from the output:

Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: outputList.size 1 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: offerItemList.size 3 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: outputList.size 2 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: offerItemList.size 4 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: outputList.size 2 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: REC 2 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: Item AB123 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: Item BC234 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: Item CD345 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: Item DE456 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: outputList.size 2 
Fri Nov 03 17:54:32 GMT 2017:INFO:OUT: REC null

I'm running out of ideas and fear I may be missing something fundamental due to my lack of experience with Groovy.

If you can put me right, I'd be most grateful.

TIA
