Question

I’m unable to figure out how to capture a screenshot when a test fails in watir. Please any help/examples?

Here is an exaample of my code

testName =  "Entered 000000 - Invalid Unit Number"    
browser.text_field(:name => 'unitNumber').set '000000'
browser.button(:name => "OpRetrieve").click
message=browser.text_field(:id => 'messages').text
if message == "Invalid Unit Number"
  f1.puts "PASSED #" + testId.to_s + ": " + testName
else
   f1.puts "FAILED #" + testId.to_s + ": " + testName + ". Message: " + message
   "Capturd screenshot"
end
testId=testId+1

Answer 1

This should do it:

browser.screenshot.save 'screenshot.png'
