Software testing is a process, to evaluate the functionality of a software application with an intent to find whether the developed software met the specified requirements or not and to identify the defects to ensure that the product is defect free in order to produce the quality product. Software testing is a series of processes that investigate and evaluate the quality of software. It ensures that software product is building by regulatory, technical, business, functional and user requirements.
Software testing is a wide process that includes several connected processes. Three things you check through these processes: software completeness regarding functional requirements; finding technical errors and ensuring the software is bug-free; assessing usability, performance, security, localisation, compatibility, and installation.
Software testing can either perform manually or by using automated tools. Some of the methods include white box testing, black box testing, and grey box testing.
In software development, everything needs to double-check before releasing the product. It is important to have a tester team who will test software and invest effort and knowledge to make sure that product is defect-free.
Software testing will point out the errors that occur during the development phases. It makes sure that the application’s performances are adequate and that customers are satisfied with it. When the delivered product is of quality, it helps in gaining the confidence of the customers.
For staying in business, having a software testing is imperative. A critical defect left undetected can cause losses in business. Every serious company will invest in a tester team and find experts who will be capable of detecting problems and flaws in a software product.
