I assume this means we probably need to do the same thing for
"html_individual_config"? Do you want me to do that?

     window.postMessage('unittest-suite-wait-for-done', '*');
   }
 
   void onTestResult(TestCase testCase) {}
 
   void onDone(int passed, int failed, int errors, List<TestCase> results,
       String uncaughtError) {
     _uninstallHandlers();
     _showResultsInPage(passed, failed, errors, results, _isLayoutTest,
         uncaughtError);
     window.postMessage('unittest-suite-done', '*');
   }
 }
 
 void useHtmlConfiguration([bool isLayoutTest = false]) {
   configure(new HtmlConfiguration(isLayoutTest));
 }
