Code

function createFile($filepath = NULL, $contents = NULL, $scheme = NULL) {
  if (!isset($filepath)) {

    // Prefix with non-latin characters to ensure that all file-related
    // tests work with international filenames.
    $filepath = 'Файл для тестирования ' . $this
      ->randomName();
  }
  if (!isset($scheme)) {
    $scheme = file_default_scheme();
  }
  $filepath = $scheme . '://' . $filepath;
  if (!isset($contents)) {
    $contents = "file_put_contents() doesn't seem to appreciate empty strings so let's put in some data.";
  }
  file_put_contents($filepath, $contents);
  $this

  // invoke the hooks.
