Facing Challenges in using Groovy DataSource on Ready API?

Hi All,

I am trying to setup Groovy DataSource on Ready API.

My Assumption is:

When i  run my groovy script(available in groovy editor in DataSource ) the data should populate data in data log.

My Script essentially contains a Map with key, value of string type.

Script:

//Boundary Values Needs to Be Populated Via Script
	//minVal 				--Pass
	//MaxVal 				--Pass
	//(maxVal-minVal)/2)  	--Pass
	//(minVal-1)  			--Fail
	//(maxVal+1)  			--Fail

	def dataMap =[:]
	def dataKey
	def expResult
//Reading Min and Max Values From TestCase Properties
	def minVal = context.expand( '${#TestCase#minVal}' )
	def maxVal = context.expand( '${#TestCase#maxVal}' )
 	def avgVal=((maxVal.toInteger()-minVal.toInteger())/2)
 	def lowVal=((minVal.toInteger())-1)
 	def highVal=((maxVal.toInteger())+1)
//Adding Five Boundary Values 
	dataMap<<[(""+minVal): "success"]
	dataMap<<[(""+maxVal): "success"]
	dataMap<<[(""+avgVal): "success"]
	dataMap<<[(""+lowVal): "failure"]
	dataMap<<[(""+highVal):"failure"]
	
	//log.info dataMap


dataMap.each{
	dataKey=it.key
	expResult=it.value
	//Adding Map Elements to 'dataKey' and 'expResult' properties
	result['dataKey']=it.key
	result['expResult']=it.value


}

After running the Script the Data Log is always updating with only last key ,value pair of Map.

And It is not listing map elements one by one .

Not sure where i am doing mistake?

Anybody can help in this?

Thanks,
