This project depends on modules from https://github.com/openaire/iis project. It contains examples of usage of various types of workflow nodes. A single example is supposed to serve as a reference/template for a person implementing their own concrete workflow node of a certain type.
This project contains tests of various types of workflow nodes. If you want to implement analogous workflow tests in some other Maven project, your test case class will have to inherit from the iis-common's eu.dnetlib.iis.common.AbstractOozieWorkflowTestCase class. Please read the description given in the javadoc of eu.dnetlib.iis.common.AbstractOozieWorkflowTestCase class for more details and see other test case classes in this project for example workflow tests.
See the src/main/scripts directory for sample scripts that build Oozie workflow packages.
