Software engineering is a branch of engineering that deals with the
development of software products. It operates within a set of principles, best practices, and methods that have been carefully honed throughout the years, changing as software and technology change. Software design is the process of envisioning and defining software solutions to one or more sets of problems. One of the main components of software design is the software requirements analysis. It is a part of the software development process that lists specifications used in software engineering. Software design is a process to transform user requirements into some suitable form, which helps the programmer in software coding and implementation. Software testing is the process of evaluating and verifying that a software
product or application does what it is supposed to do. The benefits of testing include preventing bugs, reducing development costs and improving performance.
