//
if ((onlyFailed && test->isTestOk()) || (onlySelected != -1 && n != onlySelected)) continue;
//
emit pluginTestRunning(test);
// get video information

// try to download video
emit workingProgress(n * 2 + 1, tests->count() * 2, QString("Testing <b>%1</b> video download... [2/2]").arg(test->getPluginTitle()));
Http *http = new Http();
