How to place the Groovy in centralized Groovy Library and access that class from any script

Thanks for the reformatting I think I understand now...

Your code was missing a couple of closing brackets, this might of just been a cut and paste error. Also you will need to pass in the context and log Ready API variables and your file variable to your static method. Assuming your code is now:

package com.Linos.readyapi.util.property.propertyvalidation
import com.eviware.soapui.support.GroovyUtils
import groovy.lang.GroovyObject
import groovy.sql.Sql

class PropertyValidation {
    def static propertystepvalidation(File file, context, log) {
        //Change the name of the Properties test step below
        def step = context.testCase.testSteps['Properties']

        //Parse the xml like you have in your script
        def parsedXml = new XmlSlurper().parse(file)

        //Get the all the error details from the response as map
        def errorDetails = parsedXml.'**'.findAll {
            it.name() == 'IntegrationServiceErrorCode'
        }.inject([:]) { map, entry -> map[entry.ErrorCode.text()] = entry.Description.text(); map }
        log.info "Error details from response  : ${errorDetails}"

        def failureMessage = new StringBuffer()

        //Loop thru properties of Property step and check against the response
        step.properties.keySet().each { key ->
            if (errorDetails.containsKey(key)) {
                step.properties[key]?.value == errorDetails[key] ?: failureMessage.append("Response error code discription mismatch. expected [${step.properties[key]?.value}] vs actual [${errorDetails[key]}]")
            } else {
                failureMessage.append("Response does not have error code ${key}")
            }
        }
        if (failureMessage.toString()) {
            throw new Error(failureMessage.toString())
        }
    }
}

Save this in a file called "PropertyValidation.groovy"

From your message I think you may have the directory wrong. Just set the script library to “D:\GroovyLib”

Now because your class has specified it's package to be com.Linos.readyapi.util.property.propertyvalidation place your file "PropertyValidation.groovy" in the directory:

D:\GroovyLib\com\Linos\readyapi\util\property\propertyvalidation

Think of the package as the sub-directory within the script library directory.

You should now be able to call your static method from any ReadyAPI groovy script window as such (note the import statement, this is just needed once at the top of each script that calls your static function):

import com.Linos.readyapi.util.property.propertyvalidation.PropertyValidation
import java.io.File

def file // Obtain your file object however you need to

PropertyValidation.propertystepvalidation(file, context, log)

EDIT: To add the passing in of parameters into static method, see posts below.
