NoMethodError: undefined method

Ruby
1

I am not able to understand why it gets nil object. would someone let me
know the solution ??

following are my classes and modules.
LoginTest.rb
require ‘LoginPage’
include LoginPage
require ‘BaseClass’
include BaseClass

require ‘rubygems’
require ‘watir’
require ‘test\unit’
class LoginTest < Test::Unit::TestCase

def test_login()
username_textbox.set(“Gaurang”)
password_textbox.set(“gaurang”)
login_button.click()
end

end

LoginPage.rb
module LoginPage
def username_textbox
return @browser.text_field(:id,“Email”)
end

def password_textbox
return @browser.text_field(:id,“Passwd”)
end

def login_button
return @browser.button(:id,“signIn”)
end
end

BaseClass.rb
module BaseClass
def setup
@browser = Watir::Browser.new
@browser.goto(“http://gmail.com”)
@browser.maximize
end

end

Now when i run the LoginTest.rb it gives me following error.
NoMethodError: undefined method `text_field’ for nil:NilClass

Hi,

Do you initialize the instance variable @browser?
I think you need to call the method BaseClass.setup.

Please retry after rewriting the following code

def test_login()
username_textbox.set(“Gaurang”)
password_textbox.set(“gaurang”)
login_button.click()
end

into

def test_login()
setup() # Add this line
username_textbox.set(“Gaurang”)
password_textbox.set(“gaurang”)
login_button.click()
end

Regards,

actually the some of method is of unit test and gets invoked
automatically. And sorry, as i have put the wrong code. the code is
something like this…
require ‘rubygems’
require ‘LoginPage’

gem ‘test-unit’
require ‘test/unit’
require ‘BaseClass’

class LoginTest < Test::Unit::TestCase
extend BaseClassClass
include LoginPage

def test_third()
  puts "third"
  username_textbox.set("gaurang")
end

end

I am not including the BaseClass rather I am extending it.

So, show the exact error you are getting, together with the backtrace.
And point out the actual line of code where the exception is raised.

Also, try adding a ‘puts “in setup”’ into your setup method, to see if
it is being called.
