With the minilang deprecation and the migration to groovy, I tried to implement on the ofbiz testtools the possibility to use groovy for integration test.
My idea is to define a new element on test-suite.xsd like this
After some research and unfortunately result I found a first solution present with the linked patch.
To test it just apply the patch and run :
This execute the basetest suite with the new groovy test suite present in base/groovyScript/test/SimpleTests.groovy
I'm sure this code may be improve if you want how don't hesitate !
