Class

ClassWriter

Helper class to rewrite PHPUnit's TestCase class.

Namespace

Drupal\TestTools\PhpUnitCompatibility

Code

private static function alterTestCase(ClassLoader $autoloader) : void {
    // If the class exists already there is nothing we can do. Hopefully this
    // is happening because this has been called already. The call from
    // \Drupal\Core\Test\TestDiscovery::registerTestNamespaces() necessitates
    // this protection.
    if (class_exists('PHPUnit\\Framework\\TestCase', FALSE)) {
        return;
    }
    // Mutate TestCase code to make it forward compatible with different PhpUnit
    // versions, by adding Symfony's PHPUnit-bridge PolyfillTestCaseTrait.
    $alteredFile = $autoloader->findFile('PHPUnit\\Framework\\TestCase');
    $phpunit_dir = dirname($alteredFile, 3);
    $alteredCode = file_get_contents($alteredFile);
