Testing

Run the following command:

$ npm test

This will build scripts, run tests and generate a code coverage report. Anything less than 100% coverage will throw an error.

Watching

For much faster development cycles, run the following commands in 2 separate processes:

$ npm run build:watch

Compiles TypeScript source into the ./dist folder and watches for changes.

$ npm run watch

Runs the tests in the ./dist folder and watches for changes.
