Refer to the documentation of NativeScript CLI's ns test init command for usage.
If you encounter an issue, please log it at https://github.com/NativeScript/nativescript-cli/
If you see an error like this:
Error: connect ECONNREFUSED ::1:9876
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1195:16)
When using node 17 or higher, make sure your karma.conf.js contains a server hostname setting, for example:
// web server hostname (ensure this is present)
hostname: '127.0.0.1',
// web server port
port: 9876,
See here for changeset in CLI which adds that to all newly initialized unit test setups.
