Groovy Calling method returns error

Hi,

i have a file test1.groovy in the soapui project path

in soapui i have a groovy code named test2

test1.groovy

import com.eviware.soapui.model.testsuite.TestStepResult.TestStepStatus
import groovy.sql.Sql
import java.sql.ResultSet;

public class groovyUtilities {
def context
def testRunner
def log
def Getdata() {
def id = testCase.testSuite.project.setPropertyValue("idx","abc")

log.info id
}

in test2

def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
def projectPath = groovyUtils.projectPath
def scriptPath = projectPathGroovyScriptEngine gse = new GroovyScriptEngine(scriptPath)
externalScript = gse.loadScriptByName("test1.groovy")
instance = externalScript.newInstance(context:context, log:log, testRunner:testRunner)
assert instance != null

instance.GetData()

When i run test2 it returns:

groovy.lang.MissingPropertyException: No such property: testCase for class: groovyUtilities

What is missing here?

Thank you
