“RTM” in testing refers to “Requirements Traceability Matrix.” It’s a document that connects requirements throughout the validation process, ensuring that all requirements get addressed by design, development, and testing efforts.
The primary purpose of the RTM is to ensure that every requirement is tested, helping to ensure complete test coverage. It also helps in validating that the system/software meets the defined requirements and can quickly identify any missing or incomplete functions.
Components of an RTM:
- Requirement ID: A unique identifier for each requirement.
- Requirement Description: A brief description of the requirement.
- Source: Where the requirement originated from, such as a stakeholder or specific document.
- Design Specification: Refers to any design elements that are related to the requirement, like design documents or UML diagrams.
- Test Cases/Scenarios: Links to the test cases or scenarios that have been developed to verify the requirement.
- Test Results: Status of the test (e.g., Pass, Fail, Not Executed).
- Remarks/Comments: Any additional notes, like issues or observations regarding the requirement.
Benefits of using RTM in Testing:
- Complete Coverage: Ensures every requirement is tested.
- Easy Tracking: Allows quick tracking of test coverage, helping identify untested requirements.
- Change Management: Supports assessing the impact of a changed requirement on existing test cases.
- Defect Traceability: Makes it easier to link defects to requirements.
- Stakeholder Communication: Provides a clear view for stakeholders to understand the status of requirements.
Maintaining the RTM:
- The RTM is a living document, meaning it gets updated throughout the project lifecycle.
- It should be updated whenever there’s a change in requirements or when new test cases are added/updated.
- Regular reviews of the RTM ensure that it remains relevant and accurate.
In essence, an RTM is an invaluable tool for testers, ensuring that testing is comprehensive and aligned with the system’s requirements. It provides a clear mapping between requirements and testing efforts, ensuring no requirement goes untested.
