tracebility metrics code example

Example: what is requirement traceability matrix

Requirement Traceability Matrix (RTM) is a document that maps and 
traces user requirement with test cases. 
It captures all requirements proposed by the client and requirement 
traceability in a single document, delivered at the conclusion of 
the Software devlopement life cycle. The main purpose of 
Requirement Traceability Matrix is to validate that all requirements 
are checked via test cases such that no functionality is unchecked 
during Software testing.

We use Jira XRAY for the RTM and it generates XRAY reports to track 
the test cases. It gives me detailed report of test cases and requirements.
It gives me how many test execution, how many test run, total tests, fails, 
passes
