})Testsuite makes use of hemera-testsuite, so your setup should meet it's prerequisits, esp.:
A nats server must be installed on your machine nats.io and executable as gnatsd. So add nats-server as gnatsd to your PATH as alias, link whatever works. Check if it's available:
$ gnatsd --help
Usage: nats-server [options]
[...]Now test should succeed by running:
$ yarn test
