Bullseye Code Coverage _top_ Jun 2026

For industries like aerospace, automotive, or medical devices, Bullseye provides the rigorous documentation needed for safety standards (e.g., ISO 26262 or DO-178C).

You run your test suite normally (unit tests, integration tests, fuzzing). As the binary executes, the probes increment counters in shared memory or a .cov data file. Bullseye is remarkably low-overhead—typically 10-30% slowdown, making it viable for large test suites. bullseye code coverage

By identifying untested logical branches, teams can catch edge-case bugs before they reach the user. For industries like aerospace

The instrumented source is then compiled and linked with Bullseye’s runtime library. or medical devices

// After Bullseye instrumentation (conceptual) probe_1 = 0; // Counter for the decision if (temperature > 100 && pressure < 50) probe_1++; // Counts entry of the true branch activate_alarm();
