System testing tests the system as a whole. Once all the components are integrated, the application as a whole is tested rigorously to see that it meets the specified Quality Standards. This type of testing is performed by a specialized testing team.
System testing is important because of the following reasons:
1: System testing is the first step in the Software Development Life Cycle, where the application is tested as a whole.
2: The application is tested thoroughly to verify that it meets the functional and technical specifications.
3: The application is tested in an environment that is very close to the production environment where the application will be deployed.
4: System testing enables us to test, verify, and validate both the business requirements as well as the application architecture.
