How to use connected method of Selenium.WebDriver Package

In the process of finding a solution for this, I think I might have found a bug in Capybara (v1.1.2).

I managed to get around this problem using the following approach, instead of using the click from capybara (which would not allow me to capture an exception), I started using the click method from selenium-webdriver.

It seems that when Firefox triggers this alertbox, a string with the message

Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party

is returned as a result of object.native.click, otherwise the string

ok

is returned.

# Define the click method in ruby and call it when you're executing a 'click'

  # Public: Click the object.
  #
  # object - Capybara::Node::Element object to click.
  def click object
    return_string = object.native.click
    check_firefox_alertbox if return_string == "ok"
  end

  def check_firefox_alertbox
    if @current_browser == :firefox 
     @session.driver.browser.switch_to.alert.accept
    end
  rescue Exception => e
    puts e
  end

File open second argument is mode for file openning.

read_image = open(image).read
File.open('image.png', 'w+') do |file|
  file.write read_image
end

Your third variant works good. 5482 - length of file. File 'image.png' in same directory as your .rb file.

The resolution is

result = @driver.find_elements(:xpath, "//*[comment()[contains(.,'noindex')]]").count

class NoSuchElementError < Exception
end

names = %w[ a b c ]
on_page = %w[ a b ]

names.each do |name|
  begin
    raise NoSuchElementError if not on_page.include? name
  rescue NoSuchElementError
    puts "rescuing: #{name}"
    on_page = %w[c d]
    retry
  end
end

--output:--
rescuing: c

So you can do something like this:

names.each do |name|
  begin
    #error throwing code here
  rescue NoSuchElementError
    @driver.find_element(:id, "Next").click
    retry
  end
end

I'm not Ruby expert and can make some syntax errors but you can get general idea:

if @driver.find_elements(:link, "Save").size() > 0

This code doesn't throw NoSuchElementException

But this method will "hang" for a while if you have implicitlyWait more than zero and there is no elements on the page. The second issue - if element exists on the page but not displayed you'll get true.

To workaround try to create method:

def is_element_present(how, what)
    @driver.manage.timeouts.implicit_wait = 0
    result = @driver.find_elements(how, what).size() > 0
    if result
        result = @driver.find_element(how, what).displayed?
    end
    @driver.manage.timeouts.implicit_wait = 30
    return result
end

gem install nokogiri

You can do the same with the other gems.

This is happening because the reference or id (handle in terms of selenium webdriver) of window is set to the new window. This reference in selenium webdriver is not changed when you close the new window.

This can be determined by calling window_handle function of selenium webdriver before and after closing window. You will get the id of the window if this method is called before closing the window. But after closing the window, if you try to call it then selenium webdriver will throw error saying "no such window: target window already closed from unknown error: web view not found"

So, if you want to get back to the default window then you must switch window handle again before doing any operation on that window. Add following code snippet after closing new window:

 $driver.switch_to.window( $driver.window_handles.last )

Hope this helps.

The @driver variable does not exist, that mean the initialization is not working. Here's the minimal initialization code:

$ [sudo] gem install selenium
$ selenium install

And the code for using it:

require 'selenium'
@driver = Selenium::WebDriver.for(:chrome)

And if you're using bundler to define dependencies, you should run:

$ bundle install

And then this code:

require 'rubygems'
require 'bundler/setup'
require 'selenium'
@driver = Selenium::WebDriver.for(:chrome)

Simple typo: #district_switcher is not the same as #district-switcher.
