npm test \[lB]-- <args>\[rB]

aliases: tst, t

This runs a predefined command specified in the "test" property of a package's "scripts" object.

{
 "scripts": {
 "test": "node test.js"
 }
}

npm test
> npm@x.x.x test
> node test.js

(test.js output would be here)

If true, npm does not run scripts specified in package.json files.

Note that commands explicitly intended to run a particular script, such as npm start, npm stop, npm restart, npm test, and npm run-script will still run their intended script if ignore-scripts is set, but they will not run any pre- or post-scripts.

The shell to use for scripts run with the npm exec, npm run and npm init <package-spec> commands.
