Meaning and Importance of Traceability Matrix
Meaning: Traceability Matrix is a type of document
which is used to tracking the software requirement, related defects and the
test cases. This document is created for the satisfaction of client that will
show the coverage of requirement end to end. The elements of these documents
are the following:
i.
Ref. No.
ii.
Conditions/ Test Cases
iii.
Defects / Bug id
User or client can track the requirement properly by using
the defect id and can confirm the requirement end to end
Importance of Traceability Matrix:
i.
Traceability Matrix considers a test case
where client made some changes in his already provided requirement. Assume that
in initial requirement client was asking only for First Name and Last Name and
now he want to add Email Field also for login authentication. So tracing the
changes for this type of changes in the view of test cases will called
traceability matrix.
ii.
So as the requirement has been changed
that’s why Test engineer need to change test cases to meet newly updated
requirement.
iii.
But your test scenarios/cases are already
very lengthy, You feel unable to trace bad or unmanaged test scenarios then
that will be a problem except this thing if you properly managed the test
scenarios or cases with properly numbering etc. then that case will be very
easy what is the connected with newly test cases and where it need to set in
scenarios.
iv.
Traceability Matrix stands for links
to a business requirement with its functional requirement and related to its
corresponding Test Cases.
v.
Traceability helps to determine the
Fails Test cases and corresponding functionality easily.
vi.
Traceability also confirms / ensures that
all required test cases are executed or not. All requirements have been tested or not.
Use of Traceability Matrix:
Traceability Matrix always use in all Software Development
Life Cycle Phases:
i.
Risk analysis Phase
ii.
Design Specifications and Analysis phase
iii.
Requirement Specification phase and
Analysis phase
iv.
Unit Testing, Integrating Testing and
Source Code Analysis Phase
v.
Under Validation Testing : Functional
Testing and System Testing Phase
Types of Traceability Matrix:
i.
Backward Traceability Matrix – Mean gone
through Test Cases to Requirement
ii.
Forward Traceability Matrix – Mean gone
through Requirement to Test Cases
iii.
Bi-Directional Traceability Matrix – A
combined traceability matrix of above both types. It is a good matrix which
works from test cases to requirement and vice versa.
