How to Debug Mocha JS Tests

Note: This only works with chrome.

Execute the following command to execute a test :

NODE_ENV=test node --inspect ./node_modules/mocha-webpack/lib/cli --require ./js/tests/js/spec/setup.js --webpack-config ./webpack.config.js ./js/tests/js/spec/BallerinaTest.js --timeout 600000;

As soon as you run it, a similar url will be printed on the log.

chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:9229/0f95846c-9239-4b85-a51c-92e6be469991

Go to the url in chrome and put the breakpoint. This url is NOT static.

Do the debugging and close the browser tab to finish the test execution.

To debug all tests, execute:

npm run test-debug

Happy Debugging.
