Can I combine Json.Builder with JsonOutput in groovy? CSV to JSON - json

Question

I have to parse csv file (with some modifications) to json in groovy.When I'm trying to execute this code i have a problem with spliting some values.
Content of csv file:
TestKey;Finished;user;status
RWS.PT.001;2020-07-20T23:01:21+02:00;admin;PASS;
RWS.PT.002;2020-07-20T23:02:21+02:00;admin;PASS;
my code in groovy:
import groovy.json.*
def builder = new groovy.json.JsonBuilder()
def root = builder {
testExecutionKey 'DEMO-303'
info (
user: 'admin')
tests 'rows':'ghgh','uuuuu'
}
print JsonOutput.prettyPrint(JsonOutput.toJson(root))
def csvfile = new File('C:/temp/raportTest.csv').readLines()
def keys = csvfile[0].split(';')
def rows = csvfile[1..-1].collect { line ->
def i = 0, vals = line.split(';')
keys.inject([:]) { map, key -> map << ["$key": vals[i++]] }
}
print JsonOutput.prettyPrint(JsonOutput.toJson(rows))
my target file should looks like this:
{
"testExecutionKey": "DEMO-303",
"info" : {
"user" : "admin"
},
"tests" : [
{
"testKey" : "RWS.PT.001",
"finished" : "2020-07-20T23:01:21+02:00",
"status" : "PASS"
},
{
"testKey" : "RWS.PT.002",
"finished" : "2020-07-20T23:01:21+02:00",
"status" : "PASS"
}
]
}
Now I have:
{
"testExecutionKey": "DEMO-303",
"info": {
"user": "admin"
},
"tests": [
{
"rows": "ghgh"
},
"uuuuu"
]
}[
{
"TestKey": "RWS.PT.001",
"Finished": "2020-07-20T23:01:21+02:00",
"user": "admin",
"status": "PASS"
},
{
"TestKey": "RWS.PT.002",
"Finished": "2020-07-20T23:02:21+02:00",
"user": "admin",
"status": "PASS"
}
]
How can I input code from def rows (from JsonOutput) into JsonBuilder (instead of "rows": "ghgh").
Please help!

You over-engineered it a bit. You actually don't have to combine anything, just use the JsonBuilder and some Groovy magic:
import groovy.json.*
def kindaFile = '''
TestKey;Finished;user;status
RWS.PT.001;2020-07-20T23:01:21+02:00;admin;PASS;
RWS.PT.002;2020-07-20T23:02:21+02:00;admin;PASS;
'''.trim()
def keys
def testList = []
//parse CSV
kindaFile.splitEachLine( /;/ ){ parts ->
if( !keys )
keys = parts
else{
def test = [:]
parts.eachWithIndex{ val, ix -> test[ keys[ ix ] ] = val }
testList << test
}
}
def builder = new JsonBuilder()
def root = builder {
testExecutionKey 'DEMO-303'
info user: 'admin'
tests testList
}
println JsonOutput.prettyPrint(JsonOutput.toJson(root))
prints
{
"testExecutionKey": "DEMO-303",
"info": {
"user": "admin"
},
"tests": [
{
"TestKey": "RWS.PT.001",
"Finished": "2020-07-20T23:01:21+02:00",
"user": "admin",
"status": "PASS"
},
{
"TestKey": "RWS.PT.002",
"Finished": "2020-07-20T23:02:21+02:00",
"user": "admin",
"status": "PASS"
}
]
}
