Namespace

Drupal\update

Code

public function get() {

  // Normally the Update Manager's root path is the same as the app root (the
  // directory in which the Drupal site is installed).
  $root_path = $this->drupalKernel
    ->getAppRoot();

  // When running in a test site, change the root path to be the testing site
  // directory. This ensures that it will always be writable by the webserver
  // (thereby allowing the actual extraction and installation of projects by
  // the Update Manager to be tested) and also ensures that new project files
  // added there won't be visible to the parent site and will be properly
  // cleaned up once the test finishes running. This is done here (rather
  // than having the tests enable a module which overrides the update root
  // factory service) to ensure that the parent site is automatically kept
  // clean without relying on test authors to take any explicit steps. See
  // also \Drupal\update\Tests\UpdateTestBase::setUp().
