To build the addons, run the following command:

$ npm run addons:configure
$ npm run addons:build

Run the following command to run the tests:

$ npm run node:test

To run a specific test file, use the --test-name-pattern flag:

$ NODE_OPTIONS=--test-name-pattern=js-native-api/test_constructor/test_null npm run node:test

The test names are their relative path to the tests folder, with file extensions. The pattern can be a regular expression.
