PMC Unit Test Framework

---

Introduction

This plugin was originally written for internal use at Penske Media to provide common utilities and data mocking for unit tests in a WordPress environment. Our hope is that other teams find this plugin as useful as we do when writing unit tests in WordPress.

Installation

composer require pmc/unit-test

Usage

Create the bootstrap.php file:

<?php
namespace ExampleTestNameSpace; 

use PMC\Unit_Test\Bootstrap;
use PMC\Unit_Test\Autoloader;

// Load the composer autoloader.php file
require_once __DIR__ . '/vendor/autoload.php';

// Register the current test project namespace as needed 
Autoloader::register( __NAMESPACE__, __DIR__ );

// Instantiate the unit test bootstrap
$bootstrap = Bootstrap::get_instance();

// Activate any installed plugins as needed
$bootstrap->activate_plugins( [ 'amp' ] );

// Some custom code to load plugin with VIP plugin loader
tests_add_filter( 'plugins_loaded', function() {
	wpcom_vip_load_plugin( 'some-plugin' );
} );

// Start the unit test process
$bootstrap->start();
// EOF

Add project phpunit.xml file:

<phpunit
bootstrap="tests/bootstrap.php"
backupGlobals="false"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
>
	<testsuites>
		<testsuite name="test">
			<directory prefix="test-" suffix=".php">./tests/</directory>
		</testsuite>
	</testsuites>
	<filter>
		<whitelist processUncoveredFilesFromWhitelist="true">
			<directory suffix=".php">./src</directory>
		</whitelist>
	</filter>
	<logging>
		<log type="coverage-text" target="php://stdout" showUncoveredFiles="true" />
	</logging>
</phpunit>

Extends the PMC unit test base class:

<?php
namespace ExampleTestNameSpace;

use PMC\Unit_Test\Base;

class Test_Example extends Base {
	public function test_example() {
		$post = $this->mock->post( [
				'post_title' => 'test example',
			] )->get();
		$this->assertEquals( 'test example', $post->post_title );
	}
}
