title: use environment variable in groovy script in SOAPUI script assertion
body: <p>In script assertion of a test step in SOAP UI, I am using</p>
  
  <pre><code>def currentLoc = context.expand( '${#Global#xsd_loc}' )
  new File( currentLoc+'\\application.xsd' ).withReader
  </code></pre>
  
  <p>here xsd_loc is defined in Global Properties is preferences</p>
  
  <p>But if I declare that property in environment variable in user variables and call it using #Env# then it doesn't work.</p>
