Question

I have some common code that gets called while processing the response for every mock operation in a mock service in SOAP UI.

How and where can i define a public globally accessible function so that i can remove code duplication.

Answer 1

You can put the function in a separate script file with a .groovy extension and save this script in the scripts folder , this is in the directory where SOAP UI is installed.

SoapUI Pro adds the possibility to have a central library of Groovy
Classes that can be accessed from any script within SoapUI, which can
be useful for centralizing common tasks and functionality and for
creating SoapUI extensions. Use as follows:

• Specify which folder to use in the SoapUI Pro Preferences tab (default is /scripts). SoapUI Pro will check this folder for files
  with the “Groovy” extension and compile these upon startup. The
  folder is then checked periodically (every 5 seconds) for updates and
  new or existing scripts are compiled and re-compiled if necessary.

• Scripts should be placed in folders named after their containing package, ie a script in the package soapui.demo should be in a
  soapui/demo folder under the specified scripts folder.

• The compiled classes are added to the parent class loader of all Groovy scripts, you can access them as standard java classes.
