The Test Automation Pesticide Paradox
  • A few years ago someone explained to me the
    pesticide paradox of test automation. It was a
    term I had not heard of, and  I was given the
    following explanation

The Test Automation Pesticide Paradox
  • Imagine yourself as a farmer whose fields are
    attacked by locusts. The damage is huge and all
    of the farmers crops are lost.  The loss is
    tremendous and means his family struggle to
    survive for the year and he knows that the next
    year he must take some precautions.
  • He saves what little money he has available and
    spends this on a pesticide to treat his crops
    against locusts.

The Test Automation Pesticide Paradox
  • Sure enough the locusts attack, but they are
    systematically killed saving most of his crop.
  • The farmer is very happy but does not realize
    that his plan is flawed. 1 percent of the locusts
    did not die during the attack as they had a
    natural immunity to the pesticide.

The Test Automation Pesticide Paradox
  • Each year the farmer now sprays his crops and
    kills locusts, but each year there are more
    locusts, which are born with the natural
    immunity. 
  • Eventually the farmer realizes that he must
    change his pesticide or risk losing his crop
    again.

The Test Automation Pesticide Paradox
  • So what is the moral of the story and how does it
    relate to automation? 
  • Automation testing ( https//goo.gl/i7crr8 ) is
    often used as the means of performing tests that
    will be repeated the most natural use is around
    the regression pack, akin to the farmers
    pesticide.

The Test Automation Pesticide Paradox
  • With vast savings possible as a result of script
    automation, dramatically reducing the time taken
    to run them, it is a natural area to apply
    automation.
  •  In a well-organized test function, the subject
    of maintenance should be a natural step as
    changes are made to the function, the automated
    scripts are modified and maintained up-to-date.

The Test Automation Pesticide Paradox
  • The second aspect, which is a natural inclusion,
    is for new scripts to be automated to support
    wider regression and cover new functionality.
