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. bullseye code coverage

Bullseye is used to achieve Modified Condition/Decision Coverage (MC/DC) , which is required for ASIL-D. Bullseye’s reports can be directly submitted to certification auditors. Medical Devices (FDA Class III) The FDA requires objective evidence of test completeness. Bullseye’s ability to exclude TESTMARGIN regions (e.g., "this error handler is only for cosmic ray bit flips") and merge coverage from 10,000 hours of simulation is unmatched. Legacy Code Refactoring When taking over a million-line C++ codebase with 0% tests, Bullseye helps prioritize. Run a smoke test, generate a report, and refactor the red (uncovered) and yellow (partial) functions first. This risk-based testing approach saves months of effort. 6. Limitations and Critical Considerations No tool is perfect. Bullseye has notable constraints: Bullseye’s ability to exclude TESTMARGIN regions (e
