Debugging Redux Jest tests with node inspector

I am trying to debug Redux Jest tests from the github repo https://github.com/reactjs/redux/blob/master/test with the node inspector.

node --inspect node_modules/jest/bin/jest.js --runInBand

import { bindActionCreators, createStore } from '../src'
import { todos } from './helpers/reducers'
import * as actionCreators from './helpers/actionCreators'

describe('bindActionCreators', () => {
  let store
  let actionCreatorFunctions

beforeEach(() => {
  debugger;
  store = createStore(todos)
  ...
  ...

However I am seeing the following error when placing an debugger statement within a test, as shown above.

FAIL  test/bindActionCreators.spec.js

I am running

• node v8.9.1
• jest v21.2.1
• redux master branch

any ideas?
