Bullseye Code Coverage ((new)) -
// Original code if (temperature > 100 && pressure < 50) activate_alarm();
Developed by Bullseye Testing Technology, Bullseye Coverage is a proprietary code coverage tool designed for C, C++, and C# environments. Unlike many modern, IDE-integrated plugins, Bullseye has carved a niche for itself in highly regulated industries (automotive, medical devices, aerospace) where functional safety and certification (ISO 26262, DO-178C, IEC 61508) are non-negotiable.

Introduction: The Evolution of Code Coverage Tools In the landscape of software quality assurance, code coverage metrics serve as the bedrock for understanding how thoroughly your tests exercise your application. While open-source tools like gcov (GCC) and lcov are widely known, the commercial sector has long relied on a powerful, precision-focused solution: Bullseye Coverage .
This article provides a deep dive into the architecture, methodology, unique features, and strategic implementation of Bullseye Code Coverage. Bullseye is not just a line counter; it is a decision coverage tool. Its core philosophy is that simply knowing which lines of code executed (line coverage) is insufficient for identifying hidden logical flaws. // Original code if (temperature > 100 &&
Use Bullseye if you need certifiable decision coverage in C/C++ embedded systems, or if you must merge coverage from thousands of test runs. Use open-source tools for web or mobile apps. Conclusion: Hitting the Bullseye Bullseye Coverage is not a glamorous tool. It has a dated UI, a command-line interface that feels like 1995, and a price tag. However, for safety-critical and mission-critical software, it remains the gold standard for decision coverage.
