Rescue for ScriptError in Selenium Webdriver? - ruby

Question

I have a written a Code in Selenium Web driver to test the health of the Contact Us page of my web site.
Code is working fine. My further aim is to:
Use Rescue (to get error message when this scripts fail. Specifically when some element is not found during execution in the function > "def test_contact_us_screen_shot").
Code for reference.
require 'rubygems'
require "selenium-webdriver"
require "test/unit"
class ContactUsScreenShot < Test::Unit::TestCase
def setup
#driver = Selenium::WebDriver.for :firefox
#base_url = "http://www.mycompany.com"
#driver.manage.timeouts.implicit_wait = 30
#verification_errors = []
end
def teardown
#driver.quit
assert_equal [], #verification_errors
end
def test_contact_us_screen_shot
#driver.get(#base_url + "/contact_us")
#This method will take screenshot and save it in the same folder from where script is executed.
#driver.save_screenshot("./screen1.png")
puts "screen shot taken"
assert_equal "mycompany.com - Discuss your requirements to Outsource Software Product Development, Offshore Software Testing,", #driver.title
#driver.find_element(:id, "compan").clear
#driver.find_element(:id, "company").send_keys "My Company"
#driver.find_element(:id, "first_name").clear
#driver.find_element(:id, "first_name").send_keys "Mrityunjay"
#driver.find_element(:id, "last_name").clear
#driver.find_element(:id, "last_name").send_keys "Chauhan"
#driver.find_element(:id, "email").clear
#driver.find_element(:id, "email").send_keys "mrityunjay#gmail.com"
#driver.find_element(:id, "phone1").clear
#driver.find_element(:id, "phone1").send_keys "9999999999"
#driver.find_element(:id, "addr1").clear
#driver.find_element(:id, "addr1").send_keys "306 Office Address"
#driver.find_element(:id, "addr2").clear
#driver.find_element(:id, "addr2").send_keys "Office Address"
#driver.find_element(:id, "city").clear
#driver.find_element(:id, "city").send_keys "Dehradun"
#driver.find_element(:id, "state").clear
#driver.find_element(:id, "state").send_keys "UK"
Selenium::WebDriver::Support::Select.new(#driver.find_element(:id, "country")).select_by(:text, "India")
#driver.find_element(:id, "zip").clear
#driver.find_element(:id, "zip").send_keys "248001"
#driver.find_element(:id, "website").clear
#driver.find_element(:id, "website").send_keys "http://www.mycompany.com"
#driver.find_element(:id, "comments").clear
#driver.find_element(:id, "comments").send_keys "This is the Testing Script for Contact Us page. Please Ignore.\nThanks,\nMrityunjay Chauhan"
#driver.find_element(:name, "submit").click
assert_equal "mycompany.com - Discuss your requirements to Outsource Software Product Development, Offshore Software Testing,", #driver.title
begin
rescue Exception => e
puts e.message
#driver.save_screenshot("./error1.png")
end
puts "I am Here"
end
def element_present?(how, what)
#driver.find_element(how, what)
true
rescue Selenium::WebDriver::Error::NoSuchElementError
false
end
def verify(&blk)
yield
rescue Test::Unit::AssertionFailedError => ex
#verification_errors << ex
end
end

Answer 1

Here is an answer -- just use "find_elements" instead which gives an empty array instead of throwing an exception.

Answer 2

Do you mean something like this
begin
#driver.find_element(:name, "submit")
rescue
#driver.save_screenshot("Submit_button_not_present.png")
assert_match "true","false","Your error message"
end

Answer 3

Following Rescue code is working fine in my code...
rescue Exception => e
puts e.message
puts "Element Not Found"
#driver.save_screenshot("./Test-Results/Contact_Us_Error.png")
puts "I am Here"
end #rescue
In rescue we can trace the errors by using Log. For this we have to generated log file. Code is given below:
First define log at the start of your code as:
# Here I have created a log file in my "Test-Result" folder
$log = Logger.new('./Test-Results/logfile.log')
Next, we will move the error message to our log file using code given below:
rescue Exception => e
$log.error "This is the Error occurred when Element/s not found: #{e}"
#driver.save_screenshot("./Test-Results/Contact_Us_Error.png")
puts "I am Here"
end #rescue
Log will be something like this:
E, [2012-06-04T16:03:44.546875 #796] ERROR -- : Error in Elements when not found!: Unable to locate element: {"method":"id","selector":"compan"}
