Core Functionality Testing

While testing any software product ,functionality testing is core the aspect under focus. So what should be your approch while testing functionality of a software product.

Firstly, understand what the customer/user want from the application. The application performs various functions but one of themis very crucial. For example,when you will buy a television set what you will check first – the electricity consumed,the space accupied by TV set or the picture& sound quality. Of course,you will check out picture & sound quality.Becuase this is core functionality of a TV set. Same is with a software product. The custimer/user will first test what he expects from the software product.If it works as per his expectations,then he will go for things to test. A tester needs to identify the core functionality of software product under test. If that works fine,half of the work is done.

That means,test the application from real world propective,by using it as actual user.
