Ignore stories folder when testing

[dclawson]

How do you ignore the src/stories directory when running a --coverage test?

I am using a create-react-app base and have tried the following in my package.json

"jest": {
  "collectCoverageFrom": [
    "src/**/*.{js,jsx}",
    "!<rootDir>/node_modules/",
    "!<rootDir>/src/stories/"
  ]
}

It looks like you can't pass options to jest via that mechanism in CRA (facebook/create-react-app#922).

You can pass an argument to jest on the commandline though:

npm test -- --coverage --collectCoverageFrom='["src/**/*.{js,jsx}","!src/**/stories/*"]'

Do you think we should add some documentation about this?

Thanks @tmeasday.

Yes, I think it would be helpful for --coverage tests.
