Software testing is a technique for jointly determining whether the actual piece of software complies with specifications and is error-free. It comprises manually or automatically executing software or system components in order to evaluate one or more noteworthy characteristics. Testing is essential because software errors may be expensive or even harmful. Software faults might lead to financial and human losses. In the testing process, the characteristics of the software product are reviewed for compliance with specifications in terms of any unmet needs, bugs or mistakes, security, reliability, and performance. Types of testing are unit, integration, system, and more.
