Fail to use statement IF in Selenium (With Ruby)

rubyonrails-talk
#1

Currently I’m trying use a statement IF (If a button appears in the page, then run the IF), see the method Login in the system:

If the button doesn’t appear in the page, I would like to run the next method Remove and add new expense

require "selenium-webdriver"
require "rspec"
require "rspec/expectations"

describe "#Add simple expense and after add a receipt", :suitee => true do

before(:all) do
  @driver = Selenium::WebDriver.for :  chrome
@base_url = "http://sitetest.com"
  @driver.manage.window.maximize
end

it "Login in the system" do
  @driver.get(@base_url)
  @driver.find_element(:id, "user_email").send_keys "rafael@gmail.com"
  @driver.find_element(:id, "user_password").send_keys "123456"
  @driver.find_element(:name, "commit").    click
if(@driver.find_element(:css, ".btn.btn-lg.btn-success.btn-block").displayed?)
        @driver.find_element(:css, ".btn.btn-lg.btn-success.btn-block").        click
@driver.find_element(:css, ".introjs-button.introjs-skipbutton").        click
@driver.find_element(:css, ".i.i-pencil").    click
end
end

it "Remove and add new expense" do
  begin
    while(@driver.find_element(:css, ".i.i-pencil.icon").displayed?)
     button = @driver.find_element(:id, "expense-bulk-select")
     @driver.action.click(button).     perform delete = @driver.find_element(:id, "delete-multi-btn")
     @driver.action.click(delete).     perform
waitDisplayModal = Selenium::WebDriver::Wait.new(:timeout => 10)
     waitDisplayModal.until {@driver.find_element(:class => "bootstrap-dialog-footer-buttons")}
     @driver.find_element(:xpath, "//div[3]/div/div/button[2]").     click sleep 3
  end
rescue Selenium::WebDriver::Error::NoSuchElementError
   @driver.find_element(:id, "current_expense_merchant").send_keys "Taxi to work"
   @driver.find_element(:id, "current_expense_amount").send_keys "50"
   @driver.find_element(:id, "button-add-expense").   click
waitDisplayIconTrash = Selenium::WebDriver::Wait.new(:timeout => 20)
   waitDisplayIconTrash.until {@driver.find_element(:css => ".i.i-pencil.icon")}
 end
end

 after(:all) do
  @driver. quit end
end

``

My problem: When I run this script, appears this in my console:

Failure/Error: if(@driver.find_element(:css, ".btn.btn-lg.btn-success.btn-block").displayed?)
 Selenium::WebDriver::Error::NoSuchElementError:
   no such element
(Session info: chrome=42.0.2311.135)
     (Driver info: chromedriver=2.9.248304,platform=Linux 3.13.0-24-generic x86_64)

``

That is, the IF is not working as I would like. How can I fix it?

It means that the driver cab’t fins the CSS element you pass in, -

.btn.btn-lg.btn-success.btn-block

in your case.

You can check the displayed page by adding the below statement just before your IF statement:

save_and_open_page

One more thing is to check if you enable selenium ddriver in your rspec config file:

Capybara.default_driver = :selenium

Hello Javix,

Thanks for reply. Well, I’m using only selenium + rspec, no capybara.

I want to just make one condition: IF find the button…clicks, else continues execution of the other methods

#5

If the button doesn’t exist, you’re calling displayed? on it anyway.

@Scotte:

An element can exist but be hidden, that’s what #displayed? method checks according the API docs:

def displayed?
  bridge.isElementDisplayed @id
end

The problem with the search by CSS is that you can have them more than one on a page. What if you try to find the same button by id ? Just add one your HTML code to see what will happen.

#7

Hey Scott,

I’ve tried without displayed but appears the same error.

#8

The error points it out clearly that the element does not exist on the page. Try to check the html CSS code to compare with one you test.

#9

but that’s exactly what I want! I know that sometimes the element will not appear on the screen, so I need it to run another method, it is exactly this treatment I am trying to do. for this reason I put the IF condition. If the element exists, takes an action, orexists, performs the following method. Just to be clear, how would you do this?

As I suggested, I’d change CSS to an ID and see what it will give.
Then I would check if there is no typo in CSS you of the button under test.

If there is still a weird behaviour I would try another gem, e.g. capybara, phantom JS, etc.

Take a try and come back with your results.

Rafael,

**Login in the system … and … **Remove and add new expense are NOT methods.

In RSPEC they are test code blocks and they will always run. You can create methods in your code using

def foo

end

def bar

end

it ‘run my tests’ do

if condition

foo

else

bar

end

end

By they way you have a typo here: :suitee => true
