This project runs tests with Cypress and collect code coverage using v8 native Profiler and the Chrome Debugger Protocol for then generating reports using c8.

NOTE: This project is really a PoC... I gathered together a set of plugins for Cypress amongst which this one which aims at consolidating what I did here.

Well... in this case just clone the project and tailor it to your needs. Happy hacking!

git clone https://github.com/glromeo/cypress-c8.git
cd cypress-c8
yarn install
yarn ci

the report will be available in coverage/index.html

This project follows the convention explained here

The only way I could get electron to enable CDP is to use the environment variable

ELECTRON_EXTRA_LAUNCH_ARGS=--remote-debugging-port=8315

...if anyone managed to get it working with launchOptions, please help!
