Hello folks ! Today I am going to tell you a story of three friends …. Yes you guessed it right, one of them is me . All three of us were a gang of notorious beings – blocking a code here, hiding a window there, disabling a button for the poor user or crashing the application a few times ! But we were living happily in our world until came in the big monster ‘The Tester’. Oh what a sweet fellow to begin with. He entered out territory with a gentle smile, its only later did we realize that he captured every corner of our house. He specially looked for the crevices and deep holes. God ! …. how difficult our survival became. Every morning when he came, we tried to hide ourselves and pray for the evening to come so that he would leave for the day. But how long could we, the tiny creatures survive this big bad monster and one day the inevitable happened and our lives changed forever.
