Yes plsease,

To compile and run the tests:

npm i
npm test

This will also generate test coverage in the coverage/lcov-report/index.html. There are coverage goals, try not to break them.

During development, there is a typescript watcher that will rerun tests upon .ts save:

npm run watch

Debugging should be available in VSCode via the "Mocha Tests" configuration.

Style rules follow tslint settings, linter executes upon npm test you can also:

npm run tslint
npm run tslint-fix
