Istanbul nyc to exclude test files

unit-testing mocha.js istanbul
Manu picture Manu · Feb 8, 2017 · Viewed 9.6k times · Source

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.
