To test that CLI parser is functioning correctly, I have constructed a test harness, which automates the process of running the CLI tool against different projects, and validates the results.
The projects used for testing purposes are stored in the ./acceptance/ directory. The tests themselves are written as python unit tests, and can be found in the ./harness/ directory. Output from the tests include logs produced by the CLI tool, and produced cypher queries. These all end up in the ./tooling directory (this will be automatically created if not there).
To run the tests, run ./run.sh build. This builds the CLI tool and then runs the tests. If you don't want to build the cli tool, just use ./run.sh.
