[Selenium + Ruby] Working with conditions

[Rafael C.]

Currently my test check if element is present in the screen. If element is present then run a specific action, else the test continuous normally. See my code:

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


describe "Current Expense" do


  before(:all) do
    @driver = Selenium::WebDriver.for :firefox
    @base_url = "http://the-internet.herokuapp.com/disappearing_elements"
    @driver.manage.window.maximize
  end
 
  after(:all) do
    @driver.quit  
  end


  it "Check icon" do
    @driver.get(@base_url)
    if expect(@driver.find_element(:xpath, "//*[@href='/gallery/']").displayed?).to be_truthy
      @driver.find_element(:xpath, "//*[@href='/gallery/']").click
      sleep 2
      puts "element appears"
    else
      puts "element NOT appears"
    end
  end
end

When the element is present, the message appears, but when the element not is present in the page, occurs an error and the message of "ELSE" not run.

someone help me?

not sure about Ruby but in Java, we can solve using try/catch block. In case of error code goes to catch block. Inside catch block, you can write your 2nd flow code.

You appear to be using an rspec expectation for flow control. Rspec is going to raise an exception when that expectation is not met. Don't use exception handling for flow control.

[Matthew Metzger]

I think you're suggesting he use a try / catch block to achieve flow control with exception handling. This is usually a bad idea.

[Selenium Framework]

try catch in java is almost similar to begin, rescue block in Ruby. So you can try your code something like this

 begin

  expect(@driver.find_element(:xpath, "//*[@href='/gallery/']").displayed?).to be_truthy

 rescue NoSuchElementException: e
    puts "The element is not found within the timeout"
 end
