Reading Time: 3 minutes What is Traceability Matrix? (TM)A Traceability Matrix is a document that co-relates any two-baseline documents that require a many-to-many relationship to check the completeness of the relationship. It is used to track the requirements and to check the current project requirements are met. What is RTM (Requirement Traceability Matrix)?Requirement Traceability Matrix or RTM captures all requirements proposed by the client or software development team and their traceability in a single document delivered at the conclusion of the life-cycle. In other words, it is a document that maps and traces user requirement with test cases. The main purpose of Requirement Traceability Matrix is to see that all test cases are covered so that no functionality should miss while doing Software testing. In this tutorial, you will learn- What is Traceability Matrix? (TM) What is RTM (Requirement Traceability Matrix)? Why RTM is Important? Which Parameters to include in Requirement Traceability Matrix? Types of Traceability Test Matrix How to create Requirement Traceability Matrix Advantage of Requirement Traceability Matrix Requirements Traceability Matrix (RTM) Template Why RTM is Important?The main agenda of every tester should be to understand the client’s requirement and make sure that the output product should be defect-free. To achieve this goal, every QA should understand the requirement thoroughly and create positive and negative test cases. This would mean that the software requirements provided by the client have to be further split into different scenarios and further to test cases. Each of this case has to be executed individually. A question arises here on how to make sure that the requirement is tested considering all possible scenarios/cases? How to ensure that any requirement is not left out of the testing cycle? A simple way is to trace the requirement with its corresponding test scenarios and test cases. This merely is termed as ‘Requirement Traceability Matrix.' The traceability matrix is typically a worksheet that contains the requirements with its all possible test scenarios and cases and their current state, i.e. if they have been passed or failed. This would help the testing team to understand the level of testing activities done for the specific product. Which Parameters to include in Requirement Traceability Matrix? Requirement ID Requirement Type and Description Test Cases with Status Above is a sample requirement traceability matrix. But in a typical software testing project, the traceability matrix would have more than these parameters. As illustrated above, a requirement traceability matrix can: Show the requirement coverage in the number of test cases Design status as well as execution status for the specific test case If there is any User Acceptance test to be done by the users, then UAT status can also be captured in the same matrix. The related defects and the current state can also be mentioned in the same matrix. This kind of matrix would be providing One Stop Shop for all the testing activities. Apart from maintaining an excel separately. A testing team can also opt for requirements tracing available Test Management Tools. Types of Traceability Test Matrix In Software Engineering, traceability matrix can be divided into three major component as mentioned below: Forward traceability: This matrix is used to check whether the project progresses in the desired direction and for the right product. It makes sure that each requirement is applied to the product and that each requirement is tested thoroughly. It maps requirements to test cases. Backward or reverse traceability: It is used to ensure whether the current product remains on the right track. The purpose behind this type of traceability is to verify that we are not expanding the scope of the project by adding code, design elements, test or other work that is not specified in the requirements. It maps test cases to requirements. Bi-directional traceability ( Forward+Backward): This traceability matrix ensures that all requirements are covered by test cases. It analyzes the impact of a change in requirements affected by the Defect in a work product and vice versa. How to create Requirement Traceability MatrixLet's understand the concept of Requirement Traceability Matrix through a Guru99 banking project. On the basis of the Business Requirement Document (BRD) and Technical Requirement Document (TRD), testers start writing test cases. Let suppose, the following table is our Business Requirement Document or BRD for Guru99 banking project. Here the scenario is that the customer should be able to login to Guru99 banking website with the correct password and user#id while manager should be able to login to the website through customer login page. While the below table is our Technical Requirement Document (TRD). Note: QA teams do not document the BRD and TRD. Also, some companies use Function Requirement Documents (FRD) which are similar to Technical Requirement Document but the process of creating Traceability Matrix remains the same. Let's Go Ahead and create RTM in Testing Step 1: Our sample Test Case is "Verify Login, when correct ID and Password is entered, it should log in successfully" Step 2: Identify the Technical Requirement that this test case is verifying. For our test case, the technical requirement is T94 is being verified. Step 3: Note this Technical Requirement (T94) in the Test Case. Step 4: Identify the Business Requirement for which this TR (Technical Requirement-T94) is defined Step 5: Note the BR (Business Requirement) in Test Case Step 6: Do above for all Test Cases. Later Extract the First 3 Columns from your Test Suite. RTM in testing is Ready! Advantage of Requirement Traceability Matrix It confirms 100% test coverage It highlights any requirements missing or document inconsistencies It shows the overall defects or execution status with a focus on business requirements It helps in analyzing or estimating the impact on the QA team's work with respect to revisiting or re-working on the test cases Let's learn RTM with an example in the Video Click here if the video is not accessible Requirements Traceability Matrix (RTM) Template Click below to download RTM Template Excel File Download the RTM Template Excel(.xlsx)
