Different eslint rules based on file extension

Question

Is it possible to have different rules applied to files based on their files extension? For example I have [test].spec.js test spec files residing along my source code, but I like to add rules that only apply to them only.

This was added. Docs here

example from the docs

{
  "rules": {
    "quotes": [ 2, "double" ]
  },

  "overrides": [
    {
      "files": [ "bin/*.js", "lib/*.js" ],
      "excludedFiles": "*.test.js",
      "rules": {
        "quotes": [ 2, "single" ]
      }
    }
  ]
}

Effecitively you can supply globs and a set of rules that override the default rules for files that match each glob.
