no-mocha-arrows

Description#

Mocha discourages passing arrow functions as arguments. This rule prevents their use on the Mocha globals.

Rule Details#

This rule looks for occurrences of the Mocha functions (describe, it, beforeEach, etc.) within the source code.

Incorrect#

it(() => { assert(something, false); })
it("should be false", () => { assert(something, false); })
beforeEach(() => { doSomething(); })
beforeEach((done) => { doSomething(); done(); })

Correct#

it()
it(function() { assert(something, false); })
it("should be false", function() { assert(something, false); })

This does not check usage of the require interface for Mocha, only the globals.

When Not To Use It#

• If you want to pass arrow functions to mocha, turn this rule off.
• If you have other globals which share names with mocha globals, you should turn this rule off, because it would raise warnings.
