Debugging with arbitrary NodeJS unit testing frameworks in WebStorm

I have forked a NodeJS project that uses the Test Anything Protocol (node-tap). I am using the WebStorm 8.0.1 IDE. I would now like to do step debugging when running the unit tests. Since tap seems pretty obscure in the world of Node, of course there's no run/debug configuration for that framework built into WebStorm.

I was able to run the tests through the IDE by configuring a Node.js run configuration with these settings:

Node interpreter: C:\Program Files\nodejs\node.exe
Node parameters: --debug-brk
Working directory: {my project directory}
JavaScript file: node_modules\tap\bin\tap.js
Application parameters: test/test-*.js

However, when debugging with this configuration, my breakpoints are not hit. Additionally, even inserting a debugger; statement does not trigger a break.

Is there a way for me to specifically run tap tests in WebStorm? If not, why do you suppose the breakpoints in my tests are not being hit?

In digging through the tap module, it appears that all it does is launch each test file in a child process that runs node; it then just consumes its output which conforms to the Test Anywhere Protocol.

So for me to debug, I can just debug running my test JS directly with Node. This seems to work fine. Hopefully this will help anyone else unfamiliar with this test framework.
