The coverage of requirements is a fundamental need
throughout the software life cycle. It gives project managers an
indication how well the software meets expected requirements. A
precondition for the process is to link requirements with project
artifacts, like test cases. There are various (semi-) automated
methods deriving traceable relations between requirements and
test scenarios aiming to counteract time consuming and errorprone manual approaches. However, even if traceability links
are correctly established coverage is calculated based on passed
test scenarios without taking into account the overall code base
written to realize the requirement in the first place.
In this paper we introduce the "Requirements-TestingCoverage" (ReTeCo) approach that automatically establishes
links between requirements and test cases through source code
lines which a) have been written in the context of an issue as
part of a linked requirement, b) have been committed into a
version control system, and c) produce code coverage results.
Since the approach takes into account source code lines it is able
to calculate coverage reports on a fine-grained contextual level
rather than on the result of high-level artifacts.
We show the feasibility of the approach and initial evaluation
results using the code base and test scenarios of large open source
projects.
