What is necessary to test for each item developed in the test design process?

In the test design process, it is essential to have test cases and test data for each item being developed. Test cases define the specific conditions under which tests are conducted and outline the expected outcome, ensuring that the functionality or performance of the product is verified thoroughly. They guide testers on what to test and how to interpret the results, making them a fundamental part of quality assurance.

Test data, meanwhile, refers to the inputs and configurations used during testing. Having relevant and well-structured test data ensures that tests can accurately simulate real-world scenarios and user interactions, leading to more reliable results. Together, test cases and test data allow for systematic, repeatable testing, which is critical for identifying defects and verifying that the product meets its requirements before it is released.

While a test management tool may help organize and track testing activities, and market analysis or development guidelines may inform the broader context of a project, they do not directly pertain to the specific requirements for testing items developed in the test design process. Therefore, test cases and test data are indeed necessary for effective testing.
