Exception handling in Ruby -

in following code want list of failed in rescue

puts "verifying home page"   begin        page.find('#logoanchor')     puts "logo anchor found"     page.find('.navbar-inner')     puts "header bar found"     page.find('.unstyled')     puts "found occations frame"     page.find('#easyprintpromobox')     puts "easy print frame found!"     page.find('.tabbable')     puts "3 tabs  found!"     page.find('#givingcardpromobox')     puts "create frame found!"     page.find('.footer')     puts "footer found!"    rescue     puts "logo anchor not found"   end 

here catch exception if logo anchor not found.i have catch exceptions if 1 of them not found. eg:

if logo anchor not found puts "logo anchor not present " in rescue
if header bar not present puts"header bar not found" in rescue

here's 1 way using array#partition

# dummy placeholder method `page.find` def find(el)   if rand < 0.5     raise :nop   else     true   end end  selectors = ['#logoanchor', '.navbar-inner', '.unstyled', '#easyprintpromobox', '.tabbable', '#givingcardpromobox', '.footer'] found, not_found = selectors.partition |selector|   find(selector) rescue false end  puts "found: #{found}" puts "not found: #{not_found}" 

sample output:

found: ["#logoanchor", ".unstyled", "#easyprintpromobox", ".tabbable"] not found: [".navbar-inner", "#givingcardpromobox", ".footer"] 

this should work in capybara (not tested):

selectors = ['#logoanchor', '.navbar-inner', '.unstyled', '#easyprintpromobox', '.tabbable', '#givingcardpromobox', '.footer'] found, not_found = selectors.partition |selector|   page.find(selector) rescue false end  puts "found: #{found}" puts "not found: #{not_found}"
