#### Running specific tests quickly
You can run specific tests quickly with the `test:fast` script by matching with test suites (describe) or test cases (it) using a string or regexp:
```sh
npm run test:fast -- --grep spawnJournalctl
npm run test:fast -- --grep "detect a V2 delta"
npm run test:fast -- --grep (GET|POST|PUT|DELETE)
```
The --grep option, when specified, will trigger mocha to only run tests matching the given pattern which is internally compiled to a RegExp.
