Failed to load the page. Check the URL: .. When running specs defined across multiple files about mocha-phantomjs HOT 10 CLOSED

The problem only appears to occur on Amazon Linux; tests run fine on OS X and Ubuntu 12.04. Our company runs Jenkins on Amazon Linux :/

It appeared that I an external library I was including (appmobi) was loading an FB iFrame which caused Phantomjs to fire two onloadfinished events. Still wondering why the iframe fails to load when the script is ran on ec2 but I'm closing the issue as it has nothing to do with metaskills' wonderful script!

Thanks and great work tracking it down!

Howdy, I came across this while trying to fix the problem I've been having. I have a widget that I'm writing tests for, and this widget basically creates an iframe to handle interaction with an external payment gateway. The src starts out as a reference to an empty HTML file, which is then changed based on params from the user.

When running mocha-phantomjs I keep seeing the Failed to load the page. error, no matter what src I try, and it also quits my test midway through. My test is initializing and destroying these widgets (along with the iframes) fairly quickly while it's testing other DOM-based assertions, which I'm guessing is triggering a download failure. (kind of like an XHR abort?)

Is using iframes in mocha-phantomjs or phantomjs just a no-no? Or am I doing something incorrectly. Thanks for your help!

@dominicbarnes I can not think of any reason an iframe would not work. Have you verified that the mocha tests work in a real browser first?

from mocha-phantomjs.

Yeah, that's where I started. I'm just trying to make these tests headless now.

Is it weird that i'm getting multiple Failed to load the page. errors? (basically for each time an iframe is created) Oh, and the error URL is always my input test runner file, the url never changes to reflect that it's a subresource/iframe.

Why would it be that an iframe within this page would cause an error that looks like the whole page failed?

from mocha-phantomjs.

Well mocha and phantomjs should be fine with it. This is exactly how Konacha when used with Poltergeist works. So it has to be something in this project. Can you find some time, create a fork, then make a test/iframe.html case and hook it up under test/src/mocha-phantomjs.coffee?

from mocha-phantomjs.

Ok, I've forked and added the test cases as you said. Here is the relevant commit and repo.

The specific case that causes mocha-phantomjs to fail is when an <iframe> is removed from the DOM before it is finished downloading it's content. (which is the first test-case in test/src/iframe.coffee)

Would you like me to create a new issue in Github?

from mocha-phantomjs.

I'm going to go ahead and push what I believe is a fix to the problem. It's a hack, unfortunately, but that seems to be the only option based on what I've seen from other people experiencing the same problem.

Basically, it looks like the onLoadFinished event is "bubbled" up from nested iframes. The only solution I've seen so far is to ensure that the onLoadFinished handler is only executed once, which should be the page in question. (and subsequent calls should be iframes) Please let me know what your thoughts are on this.

(btw, this change allows the failed tests from before to now pass)

Cool, BTW some of this may be helpful, or maybe no.

Konacha has its own runner and can do things with Mocha that we are not setup to do. But something in there may be useful. Just spitballing.
