Description: A testing method is a technique used to evaluate the functionality or performance of a script or application. This approach is fundamental in software development as it allows for the identification of errors, verification that functionalities meet established requirements, and assurance that the final product is of high quality. Testing methods can vary in their approach, ranging from manual to automated testing, and can include unit, integration, system, and acceptance testing. Implementing an effective testing method not only improves software quality but also optimizes the development process by reducing the time and costs associated with fixing errors at later stages. Additionally, a good testing method provides valuable documentation that can be used for future reference and for training new developers. In various development environments, testing methods are essential to ensure that changes are integrated smoothly and that the software remains in a functional state throughout its lifecycle.
