These elements are: the model, the internal representations of information the view, the interface that presents information to and accepts it from the user the controller, the software linking the two.[2][3] Traditionally used for desktop graphical user interfaces (GUIs), this pattern became popular for designing web applications.[4] Popular programming languages have MVC frameworks that facilitate the implementation of the pattern.

Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor.[1] Software testing can determine the correctness of software for specific scenarios but cannot determine correctness for all scenarios.[2][3] It cannot find all bugs. Based on the criteria for measuring correctness from an oracle, software testing employs principles and mechanisms that might recognize a problem.
