System Testing follows much the same course (Design, Implement, execute and defect) but the intent or focus is very different. While Functional Testing focuses on discrete functional requirements System Testing focuses on the flow through the system and the connectivity between related systems. For example testing to ensure the application allows the entry, activation, and recovery of a new forum member . in this case we are testing to ensure the system supports the business. There are several types of System Testing, what is required for any given release should be determined by the Scope.

★ Security

★ Performance
