Personally, I'd make a test/helper.js file. I'm doing something similar, this is what it currently looks like:

'use strict'

module.exports = {testdom, cleanup}

function testdom (markup='') {
  if (typeof document === 'undefined') {
    var jsdom = require('jsdom').jsdom
    global.document = jsdom(markup)
    global.window = document.defaultView
    global.navigator = window.navigator
  }
}

function cleanup () {
  var React = require('react')
  React.unmountComponentAtNode(document.body)
  document.body.innerHTML = ''
}

@cesarandreu nice tip!
