BullseyeCoverage

BullseyeCoverage measures C and C++ code coverage to help developers and testers locate untested code and assess testing completeness. It instruments source code and reports function coverage and condition/decision coverage. Results can be viewed interactively in Coverage Browser or generated in formats including HTML, text, annotated source code, XML, Cobertura, and CSV. Coverage data can be exported in XML or CSV, and results from multiple computers can be merged. Supported tools include Visual Studio, Clang, GCC, Xcode, CMake, Eclipse, and embedded development tools such as Code Composer Studio. Listed environments include Windows, Linux desktop and server, macOS, and embedded systems. The company identifies C/C++ developers and testers working on mission-critical systems, including embedded devices, as its core market. Instrumented execution time reportedly increases by 1.3–1.9×, while code and data size rise to 1.4×; build-time effects vary by compiler. A temporary, fully functional evaluation license costs nothing and expires at the end of the evaluation period. The paid license is perpetual, with each host operating system licensed separately.

BullseyeCoverage focuses on C and C++ coverage, with interactive viewing, multiple report formats, and support for embedded environments. Account for the reported instrumentation overhead and per-operating-system licensing when assessing fit.

It suits C and C++ developers and testers who need function or condition/decision coverage, including teams working with embedded systems. The range of supported tools and report formats may help teams incorporate coverage results into existing workflows.

BullseyeCoverage is a C and C++ code-coverage tool for teams that need to examine test reach in detail, particularly in embedded or mission-critical development. Its focused metrics and perpetual licensing suit established engineering workflows; the reported runtime and size overhead make it less appealing when instrumentation cost is a priority.

Overview

The tool instruments C and C++ source code and reports which functions and conditions tests exercise. Function coverage gives teams a view of exercised functions, while condition/decision coverage examines decision logic more closely than statement or branch coverage. That added resolution can help teams assess test completeness, but it is most useful when developers have the time and context to interpret detailed results.

Language support spans C from C90 and C++ from C++98 through current versions, including compiler extensions. This is a purposeful fit for C/C++ projects, not a general-purpose choice for teams working across unrelated languages.

Key features

Reports and combined results

Coverage Browser offers interactive review, while output options include HTML, text, annotated source code, XML, Cobertura, and CSV. XML and CSV exports give teams formats for downstream processing, and merging results from multiple computers can consolidate coverage across distributed build or test environments.

Development-tool compatibility

Supported tools include Visual Studio, Clang, GCC, Xcode, CMake, Eclipse, and embedded development tools such as Code Composer Studio. Integrations or support also involve Teamscale, MathWorks Embedded Coder, and TICS. This breadth makes BullseyeCoverage relevant to varied C/C++ toolchains, though teams should confirm that their particular compiler and workflow are covered before committing.

Instrumentation and qualification

The maker reports that instrumented execution takes 1.3–1.9× as long, with code and data size increasing to 1.4×; build-time effects vary by compiler. Those costs matter in constrained embedded environments and frequent test runs. Genuen offers a Tool Qualification Kit supporting processes for DO-178B/C, ISO 26262, and IEC 62304, a useful option for teams working within those safety frameworks.

Pricing

The Evaluation license costs nothing. It is fully functional but temporary, expires at the end of the evaluation period, and must be requested by email. It gives teams a way to evaluate the software before deciding whether the licensed arrangement fits.

The BullseyeCoverage license uses custom pricing and is a perpetual license, with optional maintenance or renewal. The maximum number of users licensed at one time applies, each host operating system requires a separate license, and pricing is discounted for 10 or more users. The separate operating-system licensing can add up for teams running across multiple host environments; the volume discount is more relevant to larger groups. Technical support is included with every purchase.

The license agreement also includes an anti-virus warranty and a 90-day warranty that the software will substantially perform according to its documentation.

Platforms

Supported environments include Windows, Linux desktop and server, macOS, and embedded systems. The license treats each host operating system separately, so cross-platform teams should account for that when sizing purchases. A continuous integration system counts as one user under the license agreement.

Who it's for

BullseyeCoverage is best suited to C/C++ developers and testers working on mission-critical or embedded systems who need function and condition/decision coverage, multiple report formats, and merged results. Teams using established C/C++ toolchains can benefit from its compatibility range. It is a weaker fit for language-diverse projects, or for teams where the reported instrumentation overhead or per-operating-system licensing is difficult to absorb.

Pros and cons

• Pros: Function and condition/decision coverage provide more detail than statement or branch coverage alone.
• Pros: Interactive viewing, several report formats, exports, and result merging support both review and consolidated workflows.
• Pros: Broad C/C++ compiler and embedded-tool support, with technical support included in purchases.
• Cons: Instrumentation increases execution time and code and data size, which can burden constrained targets or repeated runs.
• Cons: The perpetual license has custom pricing, and each host operating system is licensed separately.
• Cons: The tool focuses on C and C++, so it does not suit teams seeking coverage across a broad language mix.

• Coverage.py is a free open-source coverage tool for Python.

Verdict

Choose BullseyeCoverage when a C/C++ team needs detailed function and condition/decision coverage across desktop, server, or embedded work, and can accommodate its instrumentation costs and operating-system licensing. Look elsewhere if broad language coverage, minimal overhead, or straightforward free access matters more than its specialized metrics and workflow support.
