Importance of Traceability Matrix in Testing

A Traceability Matrix (TM), also called a Requirement Traceability Matrix (RTM), is a papers that links requirements to test cases. It secure complete test coverage, assist track defects, and provides stakeholders with visibleness into risks and progress.

This clause explicate in item about the traceability matrix, its benefit, types, and more.

Role of Traceability Matrix in Testing

Traceability Matrix tracks the association between test cases and requirements. Besides that, it play many important roles over the intact examination round. Some of them are name below.

• It ensures that your end ware meets the customer ’ s requirements altogether.
• It helps trace the root effort of any bug logged in the operation.
• It provides a glance over the testing progress roadmap and, as a result, enables the stakeholder to know the satisfactory issues before the software goes to product.
• By showing the test coverage also aid the relevant stakeholders rapidly shape the level of risk associated with getting the software pushed to production.

Advantages of Traceability Matrix

A Requirement Traceability Matrix can be greatly beneficial. Some of them are list below.

• It ensures that all the necessary have been captured through the
• It assist in assuring the client that the product is germinate as per their requirements.
• It simplifies the process of identifying any loopholes or missing feature implementation.
• It guarantee complete test coverage; as a result, all single modules and their possible combinations have been tested.
• It can keep track of the overall exam execution progress and glitch logged.
• It helps the squad to keep track of the comprehension of all of the team appendage in each cycle of the SDLC.

Types of Software Testing Traceability Matrix

The traceability matrix can be divided into three different class that are as postdate:

1. Forward traceability
2. Backward or reverse traceability
3. Bi-directional traceability

• Forward traceability:In the case of Forward Traceability, as the name propose, the requirements are mapped toward the forward way of the test cause. It is used to ensure that all the client requirements are executed correctly and tested vigorously. The main objective of using a Forward Traceability Matrix is to verify whether the production development is heading in the right direction.

SUSA automates exploratory testing with persona-driven behavior, catching bugs that scripted automation misses.

• Backward or Reverse Traceability:In the case of Backward or Reverse Traceability, the requirements are mapped into the backward direction of test suit. The main objective of this is to ensure that the product is not consuming more than what is required in any area of cryptography, testing, or pattern elements that are really not a constituent of business requirement, and thence, this finally keeps the project in the right direction.

• Bi-directional traceability: Bi-directional Traceability is a combination of both Forward and Backward Traceability matrix. It ensures that all business requisite have be covered in the test cases. It besides keeps a watch on whether there have been any enhancement in the requirements due to any late introduce bugs in the application.

Parameters to be Included in Traceability Matrix

A Requirement Traceability Matrix is usually created according to the business requirements and standards. However, there are some common argument that are always included. Few of them are mentioned below.

• Requirement ID
• Type
• Description
• Testcase ID
• Test lawsuit design
• Test execution status
• Risks if any
• Defects and status
• Unit tests
• Integration tests
• System tests
• User Acceptance Test (UAT) Status

How to create a Traceability Matrix

Here are some of the step that one must stick to while creating a traceability matrix.

Step 1: Set an end goal as per the Client ’ s Requirements

The first measure here is to assure that all the requirements have been accurately captured and a end has been set according to that. To understand this better, let us take an example of an e-commerce application for a constitution marque.

The main objective here will be to furnish a unseamed user experience for their buyer. In order to achieve that, there are two major potentiality needed.

1. Products should get listed and filtered based on different categories
2. The covering should support payments through different gateways

Here, the goals can be mentioned as prove below:

• BR_1 & # 8211; Product Viewing and Filtering:It should allow users to view and select different products and even filter them out based on different categories
• BR_2 & # 8211; Payment Options:It should countenance users to make payments through different channel, like Credit Cards, Debit Cards, UPI, Internet Banking, etc.

Step 2: Gather all the required information and supportive documents

The second step hither is to foregather all the required info and supportive documents that are needed to build the traceability matrix effectively. Once all the info is in place, we can develop all possible exam cases around it and capture it in Test Case Document (TSD). For exemplar, in this case, the examination areas can be further separate down as

• BR_1 Product Viewing and Filtering:
• FR_1: Search icon and find text box-This should give users an pick to forthwith type in their merchandise name and click on the search icon to see the matching products

• FR_2: Filters-This should give the user an selection to filter products from the catalogue based on their type.

• BR_2 Payment Options:

• FR_3: By Credit Card-This should allow users to create defrayment by Credit Card.

• FR_4: By Debit Card & # 8211;This should let users to make payments by Credit Card.

• FR_5: By UPI-This should countenance user to create payments through UPI.

• FR_6: By Internet Banking & # 8211;This should allow users to create defrayal through Internet Banking, supporting all central banks.

Step 3: Put together all the information and prepare your Traceability Matrix.

Once all the necessary info has been captured, you can project the Traceability Matrix Template. The Matrix has no definite pattern and can be tailor-make to the project requirements.

Below is one sample Traceability Matrix template.

A. Test example for each requirement enamor with their ID and Description

B. Requirements Traceability Matrix (RTM) templet:

Step 4: Validate the end result through the matrix

Now that your matrix is ready, the next step is to take up all the mentioned test case captured under TSD, update their status and bugs logged if any, and assure all the relevant Functional Requirements captured under FSD are covered and as a result, ultimately Business Requirements are covered. Through this matrix, one can easily ensure all the necessary areas are examine soundly and, so, ensure a seamless user experience.

The Requirements Traceability Matrix is an effective way to keep track of how the task is doing at each phase of the development lifecycle. It too assists relevant stakeholders in be sure that the requirements are meeting the expectations. If implemented right and accurately, RTM can easily help business leaders in avoiding end-moment issues and hassles and, as a result, improve the overall project character, reliableness, and efficiency.
