Istanbul nyc to exclude test files

Question

I'm currently getting my test files in the final coverage. That's probably because they sit alongside my components instead of having their own test folder. How can I exclude these from the coverage?

I have installed istanbul and nyc and I'm using mocha.

My script looks like:

"test": "nyc --reporter=html mocha tools/testSetup.js app/**/*.spec.js || true"

Right, after some digging I've managed to get this working. I've added

"nyc": {
    "include": "app", // Only looks in the app folder
    "exclude": "**/*.spec.js" 
}

to my package.json. Since I'm using webpack I'll probably try and find a way of defining this rule in the webpack.config.js file (if possible at all). I'll come back if I get an answer to this.

Just complementing: include and exclude may be arrays. – Refreshment
