Selenium::WebDriver::Error::JavascriptError: waiting for evaluate.js load failed Firefox 23
RspecSelenium WebdriverRspec Problem Overview
Today running my rspec tests, I get the following error whenever somewhere in a test theres a `page.execute_script' call.
Selenium::WebDriver::Error::JavascriptError:
waiting for evaluate.js load failed
# [remote server] file:///tmp/webdriver-profile20130807-3105-fpynb7/extensions/[email protected]/components/driver_component.js:8360:in `r'
# [remote server] file:///tmp/webdriver-profile20130807-3105-fpynb7/extensions/[email protected]/components/driver_component.js:392:in `fxdriver.Timer.prototype.runWhenTrue/g'
# [remote server] file:///tmp/webdriver-profile20130807-3105-fpynb7/extensions/[email protected]/components/driver_component.js:386:in `fxdriver.Timer.prototype.setTimeout/<.notify'
There is a file evaluate.js in the /resources directory (instead of components) of the path above, as it is on other machines.
This happened after updating to Firefox 23 from 22. I haven't been able to rollback yet to confirm that returning to 22 indeed fixes the problem, but that's all that's changed I believe.
Has anyone else seen this problem?
Running Kubuntu 12.04, Capybara 1.1.4, selenium-webdriver gem 2.33.0
I tried updating Capybara to 2.whatever and selenium-webdriver to 2.34.0, no change.
Rspec Solutions
Solution 1 - Rspec
I had the same problem on Mac OS X Lion with FF 23.
But the problem went away for me when I updated selenium-webdriver to 2.34.0
I added gem "selenium-webdriver", "~> 2.34.0" into my Gemfile.
bundle update selenium-webdriver
bundle install
Cucumber works fine with selenium now.
Solution 2 - Rspec
I have updated my gems to:
gem 'capybara', '~> 2.1.0'
gem 'selenium-webdriver', '~> 2.35.1'
This worked for me.
Update:
Capybara 2.1.0 has given me a problem with Phantomjs and finally I use 2.0.3 version.
Solution 3 - Rspec
I ran the below and it worked :
gem install selenium-webdriver -v "2.35.0"
Solution 4 - Rspec
I installed Selenium Webdriver recently and saw this same issue with some of my Python test scripts. After some digging I was able to determine that execute_script was hanging when it attempted to convert the JS return value into an object that could be natively evaluated (in Python for my scenario).
Would hang:
self.driver.execute_script('document.body.innerHTML="<form></form>";')
Wouldn't hang:
self.driver.execute_script('document.body.innerHTML="<form></form>"; return true;')
You can still return more complicated objects, I'm just careful to always explicitly have JS return the value I want or true if I just need the script to execute.
Hope this helps.
Some of the reading I did to figure this out:
