"The secret of successful retailing is to give your customers what they want. And really, if you
think about it from the point of view of the customer, you want everything: a wide assortment of
good quality merchandise; the lowest possible prices; guaranteed satisfaction with what you buy;
friendly, knowledgeable service; convenient hours; free parking; a pleasant shopping experience.”
- Sam Walton, World Famous Founder of Wal-Mart Corporation.
With the fastest growth of Retail in 21st century, it is important that the Retailers provide the
costumers with the most effective, user friendly and promising application. This is a challenging
opportunity for them and for the team who performs the testing of such complicated applications.
For testing team, it is always a concern what type of testing is to be performed to reach to/beyond
the expectations of the customers. They face a challenge on – what are the different interacting
applications, how they interact, what should be the response from to/fro application, is the
response sent/received correct, and the challenge keeps on going. Additionally, the testing team
has to know and understand the different testing techniques to come up with the plan which
should help them to start and achieve the goal. This is a very tedious job and requires a lot more
understanding and focussed approach.
