  // Before tearing down the test environment, ensure that no stream wrapper
  // of this test leaks into the parent environment. Unlike all other global
  // state variables in Drupal, stream wrappers are a global state construct
  // of PHP core, which has to be maintained manually.
  // @todo Move StreamWrapper management into DrupalKernel.
