`prefer-arrow-callback` with `mocha/no-mocha-arrows`

Tell us about your environment I am running tests in mocha that i want to eslint out!

• ESLint Version: ^4.6.1
• Node Version: v8.1.3
• npm Version: 5.4.1

What parser (default, Babel-ESLint, etc.) are you using? default

Please show your full configuration:

Configuration

module.exports = {
  extends: [
    'airbnb',
    'prettier',
  ],
  plugins: [
    'prettier',
    'mocha',
  ],
  globals: {
    chai: true,
    logger: true,
  },
  env: {
    node: true,
    mocha: true,
    browser: false,
  },
  rules: {
    'no-console': 'error',
    'prefer-arrow-callback': 2,
    'mocha/no-mocha-arrows': 'error',
    'prettier/prettier': ['error', {
      singleQuote: true,
      bracketSpacing: false,
      trailingComma: 'all',
    }],
  },
}

What did you do? Please include the actual source code causing the issue.

describe("my suite", function() {
});

What did you expect to happen? The above line should not error out the linter. Since i am using mocha, and mocha prefers anonymous function, not an arrow function.

Currently it errors out because of this rule:

rules: {
    'prefer-arrow-callback': 2,
  ...

I am expecting the arrow functions to be preferred everywhere except inside a case function or a suite function.

The prefer arrow-callback errors out, but it shouldn’t, probably it needs a special configuration.

What actually happened? Please include the actual, raw output from ESLint.

$ x:xx  error    Unexpected function expression     prefer-arrow-callback
