Library validated complex Oozie workflows (http://oozie.apache.org/).
Two usage scenarios:
1) Execute workflow with specified parameters, and as result get list of passed nodes.
Sample in WorkflowDirProcessorIntegrationTest
Note: from all workflow functions only "wf:conf" is supported now.
2) Check called actions exists or build full call tree in xml format
Sample in OozieWorkflowCheckerTest:
You can override properties from "config-default.xml" and "job.properties" by file with name "override.properties"
