[Selenium and Ruby] Script not run while condition

[Rafael s]

Hi,

My scenario is:

1) Access menu

2) While icon "trash" exist, remove all

3) If icon not exist, then add a new register

My code is:

require "selenium-webdriver"

require "rspec"

require 'rspec/expectations'

describe "Current Expense" do

  before(:all) do

    @driver = Selenium::WebDriver.for :firefox

    @base_url = "https://mysite.com"

    @driver.manage.window.maximize

  end

  after(:all) do

    @driver.quit   

  end

  it "Login in the system" do

    @driver.get(@base_url)

    @driver.find_element(:id, "user_email").send_keys "mye...@gmail.com"

    @driver.find_element(:id, "user_password").send_keys "123456"

    @driver.find_element(:name, "commit").click

    @driver.find_element(:xpath, "//*[@href='/expenses/current']").click

    

    wait = Selenium::WebDriver::Wait.new(:timeout => 5)

    wait.until {@driver.find_element(:id => "expense_merchant")}

  end

  

  it "Remove and add new expense" do

    begin 

    while(@driver.find_element(:xpath, "//*[@class='i i-trashcan icon']").displayed?)

      @driver.find_element(:xpath, "//*[@class='i i-trashcan icon']").click 

      sleep 2

      @driver.find_element(:xpath, "//*[@class='btn btn-primary']").click 

    end 

    rescue Selenium::WebDriver::Error::NoSuchElementError 

      @driver.find_element(:id, "expense_merchant").send_keys "Taxi to work" 

      @driver.find_element(:id, "expense_amount").send_keys "50"

      @driver.find_element(:xpath, "//*[@type='submit']").click

      sleep 3

    end 

  end

end

I need that work WHILE only in the block in bold in the above code, otherwise runs the rescue

My problem is that WHILE not stay in the loop, it runs only once and then run the rescue. Why?

Cheers,

Rafael
