Code

public function testLazyLoadOverriddenCSS() {

  // The test theme overrides system.module.css without an implementation,
  // thereby removing it.

    'test_theme',

  // This gets the form, and emulates an Ajax submission on it, including
  // adding markup to the HEAD and BODY for any lazy loaded JS/CSS files.

    'add_files' => TRUE,
  ), array(

  // Verify that the resulting HTML does not load the overridden CSS file.
  // We add a "?" to the assertion, because drupalSettings may include
  // information about the file; we only really care about whether it appears
  // in a LINK or STYLE tag, for which Drupal always adds a query string for
  // cache control.
  $this
    ->assertNoText('system.module.css?', 'Ajax lazy loading does not add overridden CSS files.');
