Mocha breakpoints using Visual Studio Code

Is it possible to add breakpoints to Mocha tests using Visual Studio Code?

Normally when debugging code, one needs to configure the launch.json, setting the program attribute to the Javascript file to execute. I am not sure how to do this for Mocha though.

Can you set breakpoints in Vscode?

Breakpoints# Breakpoints can be toggled by clicking on the editor margin or using F9 on the current line. Finer breakpoint control (enable/disable/reapply) can be done in the Run and Debug view's BREAKPOINTS section.

Did you know, that you just go into your launch config, put your cursor after or between your other configs and press ctrl-space to get a current, valid mocha config auto-generated?

Which works perfectly fine for me. Including stopping at breakpoints. ( I also had a prior, now outdated one, that did no longer for various setting-related reasons. )

enter image description here

As of VSCode 1.21.1 (March 2018) this yields:

{   "version": "0.2.0",   "configurations": [     {       "name": "Mocha (Test single file)",       "type": "node",       "request": "launch",       "runtimeArgs": [         "${workspaceRoot}/node_modules/.bin/mocha",         "--inspect-brk",         "${relativeFile}",       ],       "console": "integratedTerminal",       "internalConsoleOptions": "neverOpen",       "port": 9229     } } 

On a side-note: debug-brk is deprectated (for anyone with Node >= Version 8 at least).
