Testing and failure

Posted in Acceptance testing,Software testing by testing in London on April 21, 2009

From Silicon India

Most assumptions were then tested in isolation for its validity under ’standard test conditions’. Unfortunately, those early successes gave a false illusion that everything was fine, even though several of the chinks in the armor were not fully exposed. Absence of ‘gentle failures’ early in the project lifecycle ensured that the team thought they were on rock-solid footing.

However, in reality, we could never fully guarantee that, especially when those early cycles were done with the intent to make something work and not make something fail ! Imagine you were testing a tool to detect landmines. To do acceptance testing of the equipment, you operate it under ’specified test conditions’ and accept it. However, the enemy won’t lay mines under those very standard test conditions! Chances are extremely high that enemy’s plan will fail your equipment.
