+## Testing
+
+Tests may be run with `npm test`. Tests will trigger persistent writes to the DB, so subsequent runs of the test will fail. You must clear the DB before running the tests again. This can be done by running the following command in the project directory.
+
+```bash
+rm -rf *data*
+```
