Necessary of Testing

Why Software Testing is necessary?

Its necessary because we all make mistakes some of those mistakes are an important, but some of then are expensive or dangerous

We need to check everything and anything which we produce because things can always goes wrong, human make mistake all the time but not at all.

Since we assume that our work may have mistakes, hence we all need to check a own works, however some mistakes come from “bad assumption and blind spots” so we might make the same mistakes when we check our own work as we made when we did it so we may notice the failure  in what we have done, so s/w testing is necessary to over come the above disadvantages
