Need Info - ways to debug in phantomjs browser

[Vikram]

Hi All,

I've started using phantomjs and basic scripts like log-in are failing in it. ( which works fine in other visual browsers )

I'm not sure how to debug these kind of issues without any visual clues.

Please let me know any tips to debug failures in headless browser

Thanks in advance.

Regards,

Vikram

Take a screenshot on failure.

Have a look at https://github.com/Ardesco/Selenium-Maven-Template/blob/master/src/test/java/com/lazerycode/selenium/listeners/ScreenshotListener.java for a Java/TestNG implementation

Hi Mark,

I tried this code but it captures blank screenshot for "phantomjs" browser.

This code does work for visual browsers like Chrome / FF though.

Not sure why is it only failing for phantomjs 

Thanks,

Vikram

Can you supply your code so we can have a look.

Works on my machine ;)

If it's capturing a blank screenshot you'll want to check the response you're getting from the page. You can try getting the current url [a] our print out the page source [b] to see what might be coming back.

a (python):

self.driver.current_url

a (python):

print(self.driver.page_source)

Hope this helps,

Sorry I forgot to update on this thread earlier , there is bug with Phantomjs which results in "click" method not working at all.

I have stopped working on Phantomjs as click failure means I can't log-in to my app at all from log-in screen.

Interesting. I wonder what the bug is. I currently use Selenium's phantomjs in my testing.

Hi Doug,

sorry for delayed update , my intention of trying out "phantomjs" was to speed up automation execution.

But as this is not a real browser which customer users.

After spending days on phantomjs -> parallel execution , I have decided to go ahead with Grid setup using Docker.

As of now this is the best approach , I could find to speed up automation.

Please suggest if you have any other means.

thanks & regards,
Vikram

Hi Vikram,

No problem, everybody's busy.

I'm not so sure phantomjs would necessarily speed up execution, but it works for what I used it for on my team. We're using phantomjs version 1.9.8 / Selenium 2.42.1 on an Ubuntu 12.04.4 LTS server. I have noticed some gotchas as far as how phantomjs handles the javascript we use (angular) but for the most part, it works ok. Sounds like you've have better luck using another webdriver binding.

Good luck!
