Manufacturers typically designate a group to do a product test before the market release of a new product. For instance, a soda company develops a new flavor. Before it is mass-produced and shipped into stores, the company does a focus group discussion first, where a random group of people do a taste test and then give their opinions on the new flavored drink.
Similarly, testing should be a standard operating procedure for software development companies before they turn over the product to their clients. The tests will help the engineers and developers detect flaws or “bugs” in their work and resolve them before deployment. They have two methods to test their software: manual and automated.
