I am trying to run code coverage for my Node project, but for some reason it's not working. I am using chai+mocha+istanbul and have also tried with nyc. My code has both ES5 as well as ES6 components, and I am using compiler tags for this. The tests run fine, but the code coverage shows nothing.
11 passing (15ms)

Relevant section of my package.json:
"test": "mocha test/app.test.js --compilers js:babel-core/register",
"test:cover": "nyc npm t",
"coverage": "babel-node ./node_modules/.bin/isparta cover mocha -- --compilers js:babel-register",
"cover": "cross-env NODE_ENV=test nyc --reporter=lcov --reporter=text mocha --compilers js:babel-register test/*.js"
As you can probably figure out, I have tried different combinations and alternatives, but nothing seems to be working for me.
Relevant section of the dev dependencies:
"babel-cli": "^6.16.0",
"babel-core": "^6.26.0",
"babel-loader": "^7.1.2",
"babel-preset-es2015": "^6.24.1",

"isparta": "^4.0.0",

Please do help or suggest where I can look for for more information.
