Testing with Mocha, when I add import my test goes away


Hi, I have a question about Mocha. I’m using Meteor/React and trying to write a basic test that checks if it renders. I’m following along with this article here.

Here is what my test looks like


import { Meteor } from 'meteor/meteor'
import { Factory } from 'meteor/dburles:factory'
import ProspectForm from './ProspectForm.jsx'
import React from 'react';
import { shallow } from 'enzyme'
import { chai } from 'meteor/practicalmeteor:chai'

describe('ProspectForm', () => {
  it('should render', () => {
  const prospectForm = shallow(<ProspectForm />)


Everything worked until I added

import { shallow } from 'enzyme'

When I did that, my test went away from the browser, and it looks like this.

My first question is why would putting that line make my test disappear from the browser list of tests? If something is wrong, why doesn’t it just fail and alert me?

Second, is my import not finding the file or something to make it not work? my package.json looks like this

  "name": "myapp",
  "private": true,
  "scripts": {
    "start": "meteor run"
  "dependencies": {
    "material-ui": "^0.15.0",
    "meteor-node-stubs": "~0.2.0",
    "react": "^15.0.2",
    "react-addons-pure-render-mixin": "^15.0.1",
    "react-datepicker": "^0.27.0",
    "react-dom": "^15.0.2",
    "react-mounter": "^1.2.0",
    "react-s-alert": "^1.1.4",

  "devDependencies": {
    "enzyme": "^2.3.0",
    "react-addons-test-utils": "^15.1.0"

and my packages looks like this

So I have it installed.


I failed to look at the console of my browser before, now that I am i’m getting this error:

Does anyone have any idea?


Here is a link to my stack overflow question now…


I solved it by doing a meteor update. Bam.
