title: Taking screenshot in robot framework on step (keyword) failure
body: <p>I am  testing a GUI application with robot framework and AutoItLibrary. I would like the test to take screenshot after any failure in test, but not in the test teardown, but right after the error occurs, as the steps in between the failure and the teardown usually make the screen worth nothing. Is there a way to do that in robot? All I could get so far is a screenshot in the end of a test...</p>
  
  <p>Thanks in advance!</p>
