C/C++ Code Coverage

Structural Code Coverage for C/C++

Code Coverage for C and C++

C/C++test and C/C++test CT deliver precise coverage analysis for C and C++ systems across unit, integration, and system testing, enabling teams to identify untested areas, improve verification completeness, and produce audit-ready evidence for regulated environments. The solution supports development workflows ranging from native desktop applications to deeply embedded targets, making it suitable for modern software-defined systems as well as resource-constrained devices.

How It Works

Structural code coverage measures which parts of the program’s internal structure execute during testing. By instrumenting the application, coverage analysis records whether specific statements, branches, and logical conditions are exercised by test cases. This information helps teams evaluate the thoroughness of testing activities and identify portions of the code that have not yet been verified.

Coverage does not determine whether software behavior is correct. It provides objective evidence that the software has been exercised across relevant execution paths. For safety-critical systems, this evidence is often required to demonstrate verification completeness and reduce the likelihood of latent defects remaining undetected.

Benefit From the Parasoft Approach

Achieve Confidence in Testing Completeness

Structural code coverage provides the visibility needed to understand how thoroughly software has been exercised and where additional testing is required. By delivering accurate metrics, efficient instrumentation, and audit-ready reporting across diverse platforms, Parasoft enables organizations to build confidence in their verification activities and readiness for certification.

Coverage as a Complement to Testing

Structural coverage enhances testing by revealing the parts of software that have been exercised. But it doesn’t replace functional verification. High coverage levels indicate that tests have executed many code paths, yet meaningful test design is still required to validate correct behavior. Coverage analysis highlights untested areas, guiding teams toward more effective testing strategies and ensuring that critical logic isn’t overlooked.
