Bullseye Code Coverage ((exclusive)) -

Bullseye Coverage is a comprehensive tool designed to help developers identify untested areas of their applications. Unlike many basic coverage tools that only track line or statement coverage, Bullseye focuses on "Decision Coverage" and "Condition Coverage." This provides a much deeper analysis of the logic within your code, ensuring that not only is every line run, but every logical path and branch is exercised. Key Features of Bullseye Coverage

One of Bullseye’s most powerful (and underused) features is the ability to exclude non-testable code from coverage metrics. Using // TESTMARGIN or /* TESTMARGIN */ , you can mark: bullseye code coverage

Bullseye works by instrumenting the source code. Bullseye Coverage is a comprehensive tool designed to

| Tool | Best For | Bullseye Advantage | | :--- | :--- | :--- | | | Rapid iteration, open-source | Bullseye has decision coverage, LLVM only line/function | | Codecov / Coveralls | SaaS dashboards, PR comments | Bullseye works air-gapped (offline) for classified work | | SonarQube | Multi-language, quality gates | Bullseye’s merge engine is vastly superior for embedded | | Parasoft C/C++test | Full SDLC compliance | Bullseye is lighter-weight and cheaper | Using // TESTMARGIN or /* TESTMARGIN */ ,

This exposes the hidden bug: age >= 18 is short-circuited; if false, the OR isn't evaluated. But the decision (age >= 18 && (has_license || is_insured)) still requires both sides to be exercised as false. Bullseye tracks this precisely.

Bullseye is not just a line counter; it is a tool. Its core philosophy is that simply knowing which lines of code executed (line coverage) is insufficient for identifying hidden logical flaws.

Many free or built-in tools focus on , which simply tells you if a line of code was executed. However, a single line of code can contain multiple logical branches.
