jest: Importing lodash, rxjs fails in node environment, globals undefined

Do you want to request a feature or report a bug?

Bug

What is the current behavior?

Importing lodash@3.10.1 and rxjs@5.0.0-beta.11 fails in Jest, when testEnvironment is set to node.

Here’s a minimal repository reproduce the bug: https://github.com/fson/sandbox/tree/3ad45f19a1a3efa711cc8eba44fe349673471092/jest-node-environment-repro (just npm install and npm test).

It seems that the problem is that some globals (e.g. Array, Object) are missing from the global object created by jest-environment-node.

What is the expected behavior?

Expected to be able to import lodash and rxjs without errors thrown.

Tested on OS X 10.11.6, Node.js v6.4.0.

I’ve added the @xjamundx’s code to the setupTestFrameworkScriptFile’s file and it worked.

Maybe we need to add that in https://github.com/facebook/jest/blob/master/packages/jest-environment-node/src/index.js#L29?

I think this is the whole list

global.Array = Array
global.Date = Date
global.Function = Function
global.Math = Math
global.Number = Number
global.Object = Object
global.RegExp = RegExp
global.String = String
global.Uint8Array = Uint8Array
global.WeakMap = WeakMap
global.Set = Set
global.Error = Error
global.TypeError = TypeError
global.parseInt = parseInt
global.parseFloat = parseFloat

To get loadsh to work I had to add the following in jest-environment-node:

   // missing globals
    global.Array = Array;
    global.Object = Object;
    global.String = String;
    global.Function = Function;
    global.RegExp = RegExp;
    global.Math = Math;
    global.Number = Number;
    global.Date = Date;
    global.parseInt = parseInt

Just to add to this, importing lodash@4.15.0 also results in TypeError: Cannot read property 'prototype' of undefined, because its global detection looks like this:

/** Detect free variable `global` from Node.js. */
  var freeGlobal = typeof global == 'object' && global && global.Object === Object && global;

@sibelius I’m using the jsdom environment for now.
