WordPress loader for functional testing – 02

Following up from my previous post I’m trying to integrate WordPress automated testing suite and Codeception.

The basics

After following the installation guide I was able to run WordPress tests from the command line connecting to a Vagrant hosted database used for testing.
Once sure the test suite works I’ve tried writing a test of mine; I’ve downloaded the WordPress development release and taking a look around (the /phpunit.xml.dist file) reveals test will live in the /tests/phpunit/tests directory and that, aside for report settings and test suites definition, the file that will load WordPress is the /tests/phpunit/includes/boostrap.php file and its first doc line says it all:

/**
 * Installs WordPress for running the tests and loads WordPress and the test libraries
 */

A simple test

I want to make a simple test work and have removed all of WordPress test from the /tests/phpunit/tests folder, run the tests again and made sure no test did run
PHPUnit message that no tests were executed
Knowing that I’ve created a simple test relying on the WordPress defined wp_strip_all_tags function in the /tests/phpunit/tests folder:

<?php

/**
 * FirstTest
 *
 * @group user
 */
class FirstTest extends \PHPUnit_Framework_TestCase
{

    /**
     * @test
     * it should strip all tags
     */
    public function it_should_strip_all_tags()
    {
        $in = '<p>some</p>';
        $expected = 'some';
        $this->assertEquals($expected, wp_strip_all_tags($in));
    }
}

and running phpunit again will result in a passing test
First test green

Codeception

Since the tests work thanks to the bootstrap.php file and the settings that it loads I will try a proof-of-concept integration in Codeception creating a suite and adding tests to it; at the command line, in my current plugin project root folder, I create a new test suite

codecept generate:suite wordpress

and will point its bootstrap file to the one defined in the the wordpress folder.
I’ve checked out the WordPress folder on my desktop, in the ~/Desktop/wordpress-develop folder, and will leave the bootstrap.php file in its original position for the time being.
In the /tests/wordpress/bootstrap.php file of my project I will include the WordPress unit test bootstrap file like

<?php
$wpBootstrapFilePath = getenv('HOME') . '/Desktop/wordpress-develop/tests/phpunit/include/bootstrap.php';
include_once $wpBootstrapFilePath;

I will replicate the phpunit test above in the suite like

codecept generate:phpunit wordpress First

and run it

codecept run wordpress

It all seems to work as expected
First test run in Codeception context passes

Next

I will set up some more testing and will then move into an organic Codeception integration of the suite to skip as much configuration as possible.

I appreciate your input
