  1. Are you sure, that JavaScript errors (if any) will be returned as method call result?
  2. Does same error catching technique apply to other js-enabled drivers, like Selenium?

@aik099 visiting a URL in Selenium uses a native Selenium method. So we don't need to implement error handling (Selenium does).

@aik099 see the JS code just above. On error, it outputs some stuff to the stream.

The zombie "browser" object's method "visit" has a callback as its second argument that will be called if an error occurs. Currently this error information is just thrown away. I found it very helpful to have this error information in my project when making behat tests.

@stof has been quiet on this. I guess it is ok as it is then?

if (!empty($out)) {
throw new DriverException(sprintf('Error when loading page %s: %s', $url, json_decode($out)));
}
}
