Testing & coverage

Testing uses Jest:

npm run test — run all tests
npm run coverage — generate coverage stats

Tested areas include:

Vertex and edge creation, update, deletion
Ingestion service logic
Gremlin query generation

Current coverage is at (console output sample):

Ran all test suites.

As a note, only the services have tests written for them. I consider testing the controller to be redundant.
