[eslint] Disable eslint rules for folder

Is there a way to disable specific rules for a folder? For example, I don't want to have required JSDoc comments for all my test files in the test folder. Is there a way to do this?

The previous answers were in the right track, but the complete answer for this is going to Disabling rules only for a group of files, there you'll find the documentation needed to disable/enable rules for certain folders (Because in some cases you don't want to ignore the whole thing, only disable certain rules). Example:

{
    "env": {},
    "extends": [],
    "parser": "",
    "plugins": [],
    "rules": {},
    "overrides": [
      {
        "files": ["test/*.spec.js"], // Or *.test.js
        "rules": {
          "require-jsdoc": "off"
        }
      }
    ],
    "settings": {}
}

YAML version :

overrides:
  - files: *-tests.js
    rules:
      no-param-reassign: 0

Example of specific rules for mocha tests :

You can also set a specific env for a folder, like this :

overrides:
  - files: test/*-tests.js
    env:
      mocha: true

This configuration will fix error message about describe and it not defined, only for your test folder:

/myproject/test/init-tests.js
6:1 error 'describe' is not defined no-undef
9:3 error 'it' is not defined no-undef
