PHPUnit Testing

Step 1: Install ci-phpunit-test

Github page: link

With composer

From the root folder of your CodeIgniter application (where the application folder is in):

composer require kenjis/ci-phpunit-test --dev

Then run:

php vendor/kenjis/ci-phpunit-test/install.php

Upgrading via Composer

composer update kenjis/ci-phpunit-test

and:

php vendor/kenjis/ci-phpunit-test/update.php

Step 2: Install PHPUnit (Linux)

sudo apt-get install phpunit

Step 3: How to run tests

From the CodeIgniter application/tests folder:

phpunit

When $_SERVER variables are not found

In this case you can create a info.php file where you can list the contents of your local development server.

<?php
phpinfo();

Then you can modify the application/tests/phpunit.xml file by adding the following:

<php>
   <server name="HTTP_HOST" value="your.intranet.local"/>
   <server name="REQUEST_SCHEME" value="https"/>
   <server name="HTTPS" value="on"/>
   <server name="DOCUMENT_ROOT" value="/var/www/your-app/private_html"/>
</php>

You have to modify the values and required settings to your own needs.

More steps (if not already done)

Install npm (linux)

Reference: link

sudo npm install npm -g

Install nodejs (linux)

Reference: link

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -

followed by:

sudo apt-get install -y nodejs

and for the essentials:

sudo apt-get install -y build-essential

Install http-server (for showing coverages)

Reference: link

npm install http-server -g

Showing coverages from an intranet server

From a terminal go to the application/tests/build/coverages folder of your CodeIgniter application.
From there just type http-server. Now you can access the html page with the coverages from:

http://123.123.123.123:8080

where 123.123.123.123 is the right IP-address of your intranet server.
