@mattwr18 Shall I merge this?

[mattwr18]

oh hey @FedericoEsparza sorry, I meant to reach out to you and see if you wouldn't mind merging some PR for us... I know you're busy, but if feels weird making changes to master

This is ready to be merged, I believe, we have left the c9 code just in case we want to go back to using phantomjs

I don't know that I can merge this.

It had a lot of issues on my computer (running phx 1.4)

I pushed up a branch PR-review-branch-16-

I made several error-driven updates in pushing to simply run mix test with chromedriver. (i.e. chromedriver & mix test && pkill chromedriver)

I didn't have enough time to get it to work.

I got as far as a BEAM (OTP compiled version) issue:

You're welcome to pull down the branch and troubleshoot.

Then you can use the above link to put in a PR to the original PR.

OR if it's working on your machines, feel free to just merge the original PR

Sorry for not reviewing this sooner.

sorry for the late reply, this highlights the issue with getting it working in one environment and not properly testing it in others... really appreciate your attention to this @FedericoEsparza

it's working for @aonomike on Mac, we haven't tried it with Phoneix 1.4 because we are on 1.3.
sorry for the ignorance, but I'm a bit confused when you say you are "issues on my computer (running phx 1.4)", I thought this was project based not computer based 🤔

We can certainly merge this, if you prefer, don't want cause extra work for you, but we are also not in a huge rush, maybe we'll go forward in the book just next week.

@aonomike will put in a PR to set up the postgres info as environment variables. 😸
