Connect to Network Path with Windows security using Groovy Scripting

Hi , 

I have the below  API Response which contains a Key : Attachment Path.

I am trying to verify using Groovy Script Test Step if the file exists on that Path or not. The thing is when i try to open the path manually , i get a Windows Security popup (asking me to enter username and password) and only then can i enter the path and verify the image exists or not on that location.

 

I found a workaround where Iff i Map this Attachment Location path in widows (maps as Z drive),  i am able to use groovy to check for the existence of the image. But the problem with that is , each time my PC restarts , the Mapped drive is gone and i have to remap it for this test step to run.

 

Can some one help me if there is a way to validate the existence of the image on this server

}

 

 

Groovy Script : 

import groovy.json.JsonSlurper
def response = context.expand( '${GET Request#Response}' )
def jsonSlurper = new JsonSlurper()
def jsonObject = jsonSlurper.parseText(response)

def path = jsonObject.AttachmentPath.toString() //Get the attachment Path from the API Response
log.info path
path = path.replaceAll("]","")

Split = path.split(/[\\]/)

size = Split.length
FileName = Split[size-1]
log.info "File name is : " +FileName

 

Filename = "Z:\\\\"+FileName \\Mapped drive file name
log.info "Mapped Path : " +Filename

File file = new File(Filename)
log.info "Check if the File exists on the Mapped Path : " +file.exists()

assert file.exists().toString()=="true","File does not exist on the Server: Z:\"
