Test the file upload wizard when uploading a private file fails.

File

Tests for file.module.

Class

FileUploadWizardTestCase

Tests creating new file entities through the file upload wizard.

Code

function testFileUploadWizardPrivateFailure() {
  $test_file = $this->getTestFile('text');

  // Record the last saved file ID.
  $previous_last_fid = $this->getLastFileId();

  // Enable the private file system.
  config_set('system.core', 'file_private_path', $this->private_files_directory);

  // Step 1: Upload a basic document file.
  $edit = array();
  $edit['files[upload]'] = backdrop_realpath($test_file->uri);
  $this->backdropPost('file/add', $edit, t('Next'));

  // After the file is uploaded but before the file is saved to its final
  // location, update the private files directory to an non-writable location.
  // The /root directory is the home directory of the root user, and should
  // never be writable by the web user. As long as the directory either does
  // not exist, or is not writable, this example should work.
  $temp_private_location = '/root';
  config_set('system.core', 'file_private_path', $temp_private_location);

  // Now the file is in a temporary location. Load its entity.
  $new_fid = $this->getLastFileId();
  $new_file = file_load($new_fid);
  $this->assertTrue(file_exists($new_file->uri), 'File is temporarily uploaded.');

  // Step 3: Scheme selection.
  $edit = array();
  $edit['scheme'] = 'private';
  $this->backdropPost(NULL, $edit, t('Next'));

  // Check that a message was printed indicating the file was not saved.
  $this->assertRaw(t('@type %name was not saved.', array('@type' => 'Document', '%name' => $test_file->filename)), 'Failed private upload was deleted.');

  // Check that the file is no longer on disk.
  clearstatcache($new_file->uri);
  $this->assertFalse(file_exists($new_file->uri), 'Temporary file on disk has been deleted.');

  // Check that the file entity was deleted.
  $last_fid = $this->getLastFileId();
  $this->assertTrue($previous_last_fid == $last_fid, 'Latest file entity remains the same.');
  $this->assertFalse($new_fid == $last_fid, 'New file entity was deleted when file fails to upload.');

  // Reset the private file path so the testing framework doesn't try to
  // clean up the non-writable directory.
  config_clear('system.core', 'file_private_path');
