The Toolkit for WordPress BDD


To do Behavior Driven Development [BDD] in WordPress, you need to get the tools! Here is the stack you should use:

Operating System


Ubuntu 16 LTS. I personally use an Ubuntu 17 development server on my laptop. You can run Ubuntu on most machines with a USB memory stick, and it’s free. I use Ubuntu on the Amzaon AWS remote cloud servers and production servers. Ubuntu is a brand, but it’s just a Debian based Linux distro, so it’s future proof. If you stopped liking Ubuntu, you could switch to another distro without hassel.

Get the stack


Once you have a machine with Ubuntu running, you can load the entire development stack by running a single command:
source <(curl -s https://raw.githubusercontent.com/johndeebdd/Remote-BDD-Setup/master/installScripts/wordpress.sh)
Directions

Test Framework


Codeception with WordPress modules - PHPunit is the standard and default library for doing unit testing in PHP. CodeCeption INCLUDES PHPunit, as well as a whole series of libraries for doing BDD.

Acceptance testing


You should use the WPWebDriver and WPDb modules. You can use Selenium to drive a full browser if you want, but generally you should use PhantomJS, because it is much faster. You can write your test in the Gherkin format, or in procedural PHP. Generally, I consider Gherkin cumbersome and not worth the candle.
Sample acceptance.yml

WP-Unit testing


You should use the WPloader and WPQueries modules.

Where does code live?


Use a Git repo. Use Github for code that has a public face. Use Bitbucket for private repos [or pay Github for a private repo, either way].

How do you control outsourcer Git commit access?


First setup a few emails: freelancer1@yourdomain.com, freelancer2@yourdomain.com etc. These accounts are granted direct commit access to the repo. Give the outsourcer access to the email account. The repo itself can set a webhook to pull to the production server upon commit. When you want to freeze the outsourcer from the project, you just change the password on Github and email accounts. The project manager retains access to pull to production. The outsourcer can make a commit and it appears directly on the development server. When the commit is approved by the project manager, he does a manual pull to the production machine.

How does the outsourcer work on the code?


Some programmers will have their own IDE setups that they like and know how to use. Eclipse is the best free IDE, while PHPStorm is probably the best commercial IDE. If they know how to pull down from Github and run the code on a local host, great. If they don't know how to do that, setup a development server in the cloud for them. Our stack include the Codiad IDE, which is an open source IDE similar to PHPStorm. TO access it, just go to /codiad/ on your development server, it's all setup already.

How do you run the test suite?


cd /var/www/html/wp-content/plugins/{project dir}
bin/codecept run -vvv --html


How do I see the test results?


They appear in the terminal, or at http://yourdomain.com/wp-content/plugins/{project dir}/tests/_output/
Usually in the terminal you can use the up arrow shortcut.

How do I commit to the repo?


git add --all
git commit -m "some kind of message!"
git push origin master


How do I log in to the WordPress site?


You can log in by using the FastRegister plugin. Just enter an email in the sidebar form and viola! You're logged in as an admin.

How do I log in to a terminal?


The stack will preconfigured a user called "freelancer" with a password "password". Just SSH into the system without a pem file.
