Hi @maojindao55, we get this kind of error on Travis CI occasionally as well. It seems like a timeout issue from PhantomJS. If you're getting it every time it's possible you have a remote asset in the page which PhantomJS is trying to load. For faster experience try to not have slow assets (or no remote assets at all) in the pages loaded through PhantomJS.

BTW if you're using spiderling for integration/functional testing, have a look at our phpunit-spiderling package.

Hi @hkdobrev , this is my full code, is the target url some problem? how can I change my code? thx!

require_once __DIR__.'/../tests/bootstrap.php';

//echo $page->find('div.info > h1')->text();

@hkdobrev I think you said "For faster experience try to not have slow assets (or no remote assets at all) in the pages loaded through PhantomJS." is not the better solution, because assets is out of our control!

Answer 4 · 2015-09-23T19:47:41.000Z

Well, Spiderling was initially created for integration testing and based on your previous issue I thought you're trying to access your own pages.

I'd try to have a look at the problems you're having on this page later this week.

Cheers!

hi @hkdobrev , what is about this problem?

Answer 6 · 2016-09-28T17:37:30.000Z

@maojindao55: I appreciate this is an old question, but support issues of this kind are probably best directed to Stack Overflow (or similar).
