There are two fundamental purposes for testing: checking specifications and performing risk management. First, we run tests to verify that everything that has been specified for a product or system is found to be pre-set. If the performance is functional, if the implementation obeys what was requested and the like. Then comes the role of risk management. For both manufacturers and consumers it is important to have the notion that the product in question has little or no probability (if this is possible) of an error that makes it impossible to use.
Verify and validate Verifying and validating a software product is a process that seeks to determine if the system meets its predefined objectives. This is a process that starts early in the software development lifecycle. This is a fundamental process that can be performed by the team that made the product, but is more efficient when performed by people outside the development. Improve the quality The software testing services that we develop is often used in critical areas such as medical diagnostics, air traffic control, space missions, or salary payment (kkk). A bug in one of these applications can cause irreparable loss. Improving the quality of your software is of utmost importance as it helps ensure that the software meets the requested standards. Improve reliability In order to have good software it is necessary that its users have confidence in it. It does not do much good software that does not serve the purposes. An incorrect medical diagnosis can simply mean the loss of life. When purchasing a product the customer wants to be sure that it will be useful. Software developers need to look closely at the reliability of a program to ensure the satisfaction of those who use it. The reliability question is one of the most important aspects in choosing a product. When the product in question is software , reliability and security have to be even greater. Often the customer needs to be sure of the quality of the software to be able to acquire it. Usually the consumer expects to use a particular program and it works as expected without interruptions and failures. Usability and Operability A very important purpose of software testing is to prove that software is useful and accessible. Usability tests usually happen by a select group of users where usage is observed and studied. All aspects are important when it comes to user interaction with software. Observe ease of use, difficulties and problems are recorded and analyzed. Prevent further Bugs The term BUG comes from the year 1945, when a moth was found on a MARK II computer circuit. Anyway, since that time is one of the most detested terms between developers and users. Most errors are usually introduced in the software requirements. It can also be defined as a logical failure of a program, which may cause discrepancies in the expected results, or impossibility of performing a program's functionality. If errors are detected early, they can be prevented from migrating to the next development phase. The earlier you detect the error, the easier your debugging gets, and this can save you many exhausting hours looking for bugs.
