Demonstrates use in a mocha test script.

const assert = require('assert')
const commandLineArgs = require('command-line-args')

/*
enable partial parsing to prevent `UNKNOWN_OPTION` exceptions being thrown
if the user sets mocha-specific options (e.g. --no-colors)
*/
const options = commandLineArgs({ name: 'value', type: Number }, { partial: true })

describe('Array', function () {
  describe('#indexOf()', function () {
    it('should pass when the supplied value is between 1 and 3', function () {
      assert.ok([ 1, 2, 3 ].indexOf(options.value) > -1)
    })
  })
})
