Safari issues

[johannesjo]

When running safari (doesn't matter, if via sauce or via selenium grid), I keep encountering the following error (lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/promise.js:1549):

    Warning:

          throw error;

Is this a bug of the webddriver or does this have something to do with protractor?

[juliemr]

Hm. Related to #73?
Or #85? That one's on my plate for more investigation after this week.

[johannesjo]

I probably should mention that I'm running this from Ubuntu and over https (although I'm almost sure I tried with http as well) ... I will play around a little with all route stuff when I get home.

[juliemr]

I'm able to reproduce about 0.1% of the time with safari, which is making this a little tricky to debug. But it's a start...

[johannesjo]

@juliemr sorry for the late reply. Was a hell of a week ;)

Actually the error won't occur, if I use http instead of https. I will debug this further and let you know what I find out.

[johannesjo]

Well I'm not sure whats going on. From sauce I get the following message:

Test did not see a new command for 90 seconds. Timing out.

The url including the hash is displayed correctly in the address-bar when I'm watching the test-session live, but angulars route doesn't seem to be triggered (not the default view nor the specified one). When I dont watch the test-session and just access it afterwards from the sauce backend only about:blank is shown in the address bar.

These are the commands which get exectued:

Please let me know, if I could provide some more information.

This is definitely related to routing somehow. When I comment out any occurrences of browser.get() everything is running fine even with https. Still not sure if this is an issue of the webdriver or related to protractor.

Hi - I was running into this problem too and upgraded to 0.17.0 for this fix. While it does seem to fix the page unload event error, I am now intermittently running into the following issue:

     Error: Wait timed out after 303ms
==== async task ====
    at Protractor.get (.../node_modules/protractor/lib/protractor.js:658:15)

It seems that if the server is not quick enough to respond to the get request, the timeout will trigger. I tried increasing the timeout (to 1000) and that made everything work. Is there any chance that you can increase that timeout, or make it configurable somehow?
