Change Default Timeout and Wait Time of Capybara

One of the biggest challenge for automation is handling timeout problem. Most of the time, timeout is 60 seconds but it may sometimes not enough if you have badly designed asynchronous calls or the third party ajax calls. This makes handling timeout more complex. set large enough to tolerate network related problems. For Selenium based automation frameworks, like Capybara, default Webdriver timeout is set to Net::ReadTimeout (Net::ReadTimeout) Changing ReadTimeout If you have timeout problem for Capybara, it gives an error like above. This means that the page is not fully loaded in given timeout period. Even you can see that page is loaded correctly but webdriver wait until the Ajax calls finish. class BufferedIO #:nodoc: internal use only def initialize (io) @io = io @read_timeout = 60 @continue_timeout = nil @debug_output = nil @rbuf = '' end . . . . . def rbuf_fill beg

An Error for Selenium - Chrome vs Firefox: stale element reference

I faced an selenium error like " stale element reference " when I changed Capybara's driver to Chrome which was not occurred in webkit and firefox. This error occurs when referencing an element which is not in DOM. Chrome gives this but it doesn't appear when I use Firefox because the dynamic object is appear after the Javascript execution finishes which means that Chrome doesn't wait until javascript execution ends .  You can escape this error by checking your scenario if there is an element requiring in the DOM which is destructed by an action in the scenario or if you have loop and the DOM is updating for each iteration the object you look for changes. However in  my case, scenario is passing with FF but not Chrome which because the Chrome is passing the next step as soon as Javascript execution starts.  I just call waiting function and then assign the variable. Finally scenario is passing for both browsers.        stale element reference: element is

Running Capybara Under Chrome, Poltergeist or Firefox

As a default Capybara runs under Firefox but if you want to change your driver you have to change your javascript driver to your new driver. But you also must define your driver as registered Capybara driver. For example if you want to run with Chrome and change your driver to chrome but not define it, it gives some errors like following irb(main):007:0> visit "http://www.amazon.com" Capybara::DriverNotFoundError: no driver called :chrome was found, available drivers: :rack_test, :selenium, :poltergeist from /Library/Ruby/Gems/2.0.0/gems/capybara-2.4.1/lib/capybara/session.rb:77:in `driver' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.4.1/lib/capybara/session.rb:226:in `visit' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.4.1/lib/capybara/dsl.rb:51:in `block (2 levels) in ' if you add the following line into your env.rb module, you will successfully run under Chrome driver. Capybara.register_driver :chrome do |app| Capybara::Selenium::Driver

Selenium Error "Element is not currently interactable and may not be manipulated"

Selenium webdriver can drive different browsers like as Firefox, Chrome or Internet Explorer. These browsers actually cover the majority of internet users, so testing these browsers possibly covers the 90% of the internet users. However, there is no guaranty that the same automation scripts can work without a failure on these three browsers. For this reason, automation code should be error-prone for the browsers you want to cover. The following error is caught when the test script run for Chrome and Internet Explorer, but surprisingly there is no error for the Firefox. Selenium gives an error like below: Traceback (most recent call last):   File "D:\workspace\sample_project\sample_run.py", line 10, in <module>     m.login()   File "D:\workspace\ sample_project \test_case_imps.py", line 335, in login     driver.find_element_by_id("id_username").clear()   File "C:\Python27\lib\site-packages\selenium-2.35.0-py2.7.egg\selenium\webdriver\r

Selenium Error Message: "Can't load the profile. Profile Dir:..."

Because of an upgrade, I needed to move to new computer and new operation system so I moved my automation code to new system which is from Window 7 to Windows 8. When run the code I got the following error indicating that the Selenium can't load the profile which means that the version of the browser is not supported by the Selenium yet. If you get an error like the following one, you need to find the supported version of the browsers. Traceback (most recent call last):   File "D:\workspace\ automation_project \run_test_cases.py", line 12 4, in <module>     m = Markafoni(browser, server)   File "D:\workspace\ automation_project \test_case.py", line 8 64, in __init__     self.driver = webdriver.Firefox()   File "C:\Python27\lib\site-packages\selenium-2.25.0-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 51, in __init__     self.binary, timeout),   File "C:\Python27\lib\site-packages\selenium-2.25.0-py2.7.egg\sele

Internet Explorer Launching Gives Errors in Selenium Webdriver

As selenium user know, Selenium script can be run via FireFox, Chrome and Internet Explorer if you set up the environments correctly, you may read this post if you are un-sure. If you face an error while launching Internet explorer in selenium test automation, you need to set all the security zone in the same mode (enabled, or disabled mode). If you change security zone, selenium gives the following errors, and the last one says " Protected Mode settings are not the same for all zones " so you can set the protected mode by Tool > Internet Options > Security Tab then set Internet, Local Internet, Trusted Sites, and Restricted Sites as same mode, enabled or disabled. Then click "Apply" and "OK" and repeat your tests.
