Issue #3385846 by pooja_sharma, joachim: FileOnTranslatedEntityTest should use...

namespace Drupal\Tests\file\Functional;

use Drupal\file\Entity\File;

use Drupal\node\Entity\Node;

use Drupal\Tests\content_translation\Traits\ContentTranslationTestTrait;

// cspell:ignore Scarlett Johansson

    /** @var \Drupal\file\FileUsage\FileUsageInterface $file_usage */

    $file_usage = \Drupal::service('file.usage');

    // Enable language selector on the page edit form.

    $edit = [

      'language_configuration[language_alterable]' => 1,

    ];

    $this->drupalGet('admin/structure/types/manage/page');

    $this->submitForm($edit, 'Save');

    // Create a node and upload a file.

    $node = $this->drupalCreateNode(['type' => 'page']);

    $edit = [

    // Check if the file usage is tracked correctly when changing the original

    // language of an entity.

    $edit = [

      'langcode[0][value]' => 'fr',

    $this->drupalGet('node/' . $node->id() . '/edit');

    $node = Node::load($node->id());

    $node->set('langcode', 'fr');

    $node->save();

    $this->assertEquals($file_usage->listUsage($file), ['file' => ['node' => [$node->id() => '1']]]);
