this workflow can't be uploaded so easy:

src/test/resources/workflows $ tree
├── aggregatorNoOutput
│   ├── lib
│   │   └── oozie-examples-3.1.5.jar
│   └── workflow.xml
├── impression_rc_workflow.xml
└── phailFs_workflow.xml

I think this is no a good idea to create one more folder for the workflow which is used only once.
