Traceability matrix
Traceability matrix is a document used in software testing that helps to establish the relationship between test cases and the requirements or specifications they are designed to test. The main purpose of a traceability matrix is to ensure that all requirements have been tested and that all test cases have been created to test the requirements.
A traceability matrix typically contains a table that maps the requirements to the test cases. The requirements are listed in one column of the table, while the test cases that cover those requirements are listed in another column. In addition to the requirements and test cases, the traceability matrix may also include other information such as the status of each requirement and test case, the priority level of each requirement, and the date when each requirement was implemented and tested.
The traceability matrix helps to ensure that the testing effort is comprehensive and that all requirements are being tested. It also helps to identify any gaps in the testing process where requirements have not been adequately tested or where additional testing is required. Traceability matrix is a useful testing artifact that can be used throughout the software development lifecycle, from requirements gathering to final testing and deployment. It helps to ensure that testing is thorough, efficient and effective, and that all requirements are met. Additionally, it can be used as a tool to manage requirements changes and to assess the impact of those changes on testing efforts.
