Reasons for Testing Software

People can make mistakes, so we need to check software before delivering it to clients.
We make mistakes, there are some mistakes which are not important or serious but there may be some mistakes which should be corrected because of serious mistakes and some of them are expensive or dangerous.

As an assumption we should rectify our errors or mistakes, but there are some mistakes caused from bad assumptions and blind spots. This is another reason for these mistakes, we may not notice the flaws in what we have done.

We should assign these tasks to the reviewer. Sometimes, a reviewer can easily check or catch that error which was left or done by us. Reviewers can easily spot these flaws.

These are one reason to require software testing. Software Testing should consider major things while testing any product or application.
