Testing Definition
There are many different ways to define testing, but at its core, testing is about verifying the functionality of a system to ensure it meets the requirements. This can be done through manual or automated means, and often involves running tests against the system to see if it produces the expected results.
Different types of testing can be used to verify different aspects of the system. For example, functional testing verifies that the system performs as expected, while load testing checks that the system can handle high levels of traffic without breaking down. There are also various other types of tests that can be performed, such as regression tests (which check for regressions in existing functionality), security tests (which check for vulnerabilities), and so on.
In order to effectively test a system, it is important to have a clear understanding of what needs to be tested and how. Often, this will involve creating test plans and cases which detail the steps needed to reproduce specific issues or test specific scenarios. Once these plans and cases are created, they can be run against the system to verify that it behaves as expected.
