Class

LanguageListModuleInstallTest

Tests enabling Language if a module exists that calls LanguageManager::getLanguages() during installation.

Namespace

Drupal\Tests\language\Functional

Code

public function testModuleInstallLanguageList() {

  // Since LanguageManager::getLanguages() uses static caches we need to do
  // this by enabling the module using the UI.
  $admin_user = $this

    'access administration pages',
    'administer modules',
  ]);
  $this
    ->drupalLogin($admin_user);

  $edit['modules[language][enable]'] = 'language';
  $this
    ->drupalGet('admin/modules');
  $this
    ->submitForm($edit, 'Install');
  $this
    ->assertEquals(1, \Drupal::state()
    ->get('language_test.language_count_preinstall', 0), 'Using LanguageManager::getLanguages() returns 1 language during Language installation.');

  // Get updated module list by rebuilding container.
