WebStorm debugging not stopping on breakpoints

My app is a node.js app which I can run through command line using: npm test inside the working directory. In WebStorm, I created a new configuration that looks like this:

Node interpreter: /usr/local/bin/npm
Node parameters: test
Working directory ~/dev/project

When I hit the run button, I get the correct output:

/usr/loca/bin/npm test

> [email protected] test ~/dev/project

something else
Process finished with exit code 0

But since I have breakpoints set, it should have stopped on a breakpoint instead of getting to the Process finished part. I set my code to be pretty simple just so I can test breakpoints, so it looks like this:

"use strict";

let foo = false; (breakpoint)
let bar = true;

if (foo === bar) { (breakpoint)
    console.log('something');
} else {
    console.log('something else'); (breakpoint)
}
process.exit(1);

I also tried to make this work through command line. In my site settings, I set my Built-in server to port 12345. Can accept external connections, and allow unsigned requests.

when I run it through command line, I use:

npm --debug-brk=12345 test

I get the same result: it runs all the way to the exit point without stopping on the breakpoints.

Any ideas what I need to do to get this to work?

/usr/local/bin/npm is definitely not a Node interpreter, it's NPM package manager that is a Node.js application itself (i.e. it's run with Node.js interpreter). And test is a name of npm script, not a Node.js parameter.

If you like to debug your .js file that is run via npm test, you need to modify your npm script to include the debug options and then use NPM run configuration for debugging. Or, just create a Node.js configuration, set a valid path to Node.js execuitable there (/usr/bin/node or whatever it looks like on your system), then specify your .js file as JavaScript file:.
