Mochawesome reporter fails with mocha 4

[Kporal]

What are you trying to achieve?

When using mochawesome as reporter, codecepts fails when I've errors in my tests. The report is not generated.

npm install && npm test

What do you get instead?

/test/node_modules/mocha/lib/reporters/base.js:227
    test.titlePath().forEach(function (str, index) {
         ^

TypeError: test.titlePath is not a function

It seems to be caused by this change from the 4.0.0 release of Mocha.

My test file

// fail_test.js
const assert = require('assert');

Feature('Fail');

Scenario('fails', (I) => {
    assert.equal((1 + 1), 3);
});

My package.json

{
    "name": "test",
    "version": "1.0.0",
    "scripts": {
        "postinstall": "selenium-standalone install",
        "pretest": "selenium-standalone start 2> /dev/null &",
        "test": "codeceptjs run fail_test.js --reporter mochawesome"
    },
    "engine": "node >= 8",
    "devDependencies": {
        "codeceptjs-webdriverio": "^1.1.0",

        "mochawesome": "^2.3.1",
        "selenium-standalone": "^6.9.0"

Could this be that in this config you have 2 verisons of Mocha installed?
if so that explains everything. We need to update dependency to support latest mocha

[Kporal]

Yes you're right. I think codeceptjs dependency needs to be updated to avoid that issue.

Is that still an issue after having only one version of Mocha in your project, ie Mocha 4.x ?
