SyntaxError: Unexpected token export

Hello,

I tried add zeppelin-solidity(1.7.0) to the react-box and run the test cases. I modified test/simplestorage.js to below

import ether from 'zeppelin-solidity/test/helpers/ether';

var SimpleStorage = artifacts.require("./SimpleStorage.sol");

contract('SimpleStorage', function(accounts) {

  it("...should store the value 89.", function() {
    return SimpleStorage.deployed().then(function(instance) {
      simpleStorageInstance = instance;

      return simpleStorageInstance.set(89, {from: accounts[0]});
    }).then(function() {
      return simpleStorageInstance.get.call();
    }).then(function(storedData) {
      assert.equal(storedData, 89, "The value 89 was not stored.");
    });
  });

});

When I run the truffle test command, it throws Unexpected token export error

11:31 $ truffle test test/simplestorage.js
Using network 'development'.

How can I fix this?

Since this Truffle box hasn’t been updated in a long time, I’ve made a new Truffle Box to compete with this current one. In my truffle box (https://github.com/adrianmcli/truffle-react), I have integrated Babel into the Truffle project itself.

I also personally tested the latest zeppelin-solidity library with it. You can do the following in your test with no problems:

import ether from 'zeppelin-solidity/test/helpers/ether';

I tried to make the Truffle Box account for the most popular errors in this repo’s issue tracker. So I’ve also moved the frontend to its own separate folder, made sure React is not ejected, and also upgraded to Web3 1.0.

Hope this helps you guys.

@adrianmcli Thanks for the clarification. I ended up taking the plunge and migrated to your box. Took most of the day, but the setup seems vastly simpler and quite a lot better now. Thanks a lot!
