I tried to perform a test on the WC_VERSION constant.
The main class :
class WC_Custom_Variable_Products_Dependencies {
/** minimum WooCommerce version required by this plugin */
const MINIMUM_WC_VERSION = '3.7.9';
public function __construct() {
add_action( 'admin_init', [$this, 'check_wc_version']);
}
protected function check_wc_version() {
return version_compare(WC_VERSION, self::MINIMUM_WC_VERSION , '>=');
}
}
The test class :
require_once 'includes/class-wc-custom-variable-products-dependencies.php';
class WC_Custom_Variable_Products_DependenciesTest extends WP_UnitTestCase {
public function setUp() {
parent::setUp();
$this->class_instance = new WC_Custom_Variable_Products_Dependencies();
}
/**
* Tests the protected functions
*
* @param Object $method
* @return bool
*/
private function makeReflection($method) {
$reflection = new ReflectionClass('WC_Custom_Variable_Products_Dependencies');
$protectedMethod = $reflection->getMethod($method);
$protectedMethod->setAccessible(true);
return $protectedMethod->invokeArgs($this->class_instance, ['']);
}
public function test_check_wc_version() {
$result = $this->makeReflection('check_wc_version');
$this->assertTrue($result);
}
}
And PHPunit return :
Use of undefined constant WC_VERSION - assumed 'WC_VERSION'
does this mean in the test, Woocommerce is not loaded?
