Class

AssertContentTrait

Provides test methods to assert content.

Namespace

Drupal\KernelTests

Code

protected function assertThemeOutput($callback, array $variables = [], $expected = '', $message = '') {
    
    /** @var \Drupal\Core\Render\RendererInterface $renderer */
    $renderer = \Drupal::service('renderer');
    // The string cast is necessary because theme functions return
    // MarkupInterface objects. This means we can assert that $expected
    // matches the theme output without having to worry about 0 == ''.
