Software testing 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.   Types of software testing There are many different types of software tests , each with specific objectives and strategies: ·          Acceptance testing : Verifying whether the whole system works as intended. ·          Integration testing : Ensuring that software components or functions operate together. ·          Unit testing : Validating that each software unit performs as expected. A unit is the smallest testable component of an application. ·          Functional testing : Checking functions by emulating business scenarios, based on functional requirements. Black-box testing is a common way to verify functions. ·          Performance testing : Testing how the software performs under different workloads. Load testi
