What is Coco Code Coverage?
Coco by Qt is an advanced code coverage and test analysis platform designed for developers, QA engineers, and compliance leads building safety-critical or performance-sensitive software. Supporting C, C++, C#, QML, and Tcl, Coco measures coverage from statement and branch analysis to Modified Condition/Decision Coverage (MC/DC), giving a granular view of code quality and test completeness. It integrates seamlessly with IDEs like Visual Studio, Eclipse, and Qt Creator, as well as CI/CD tools such as Jenkins and CMake, enabling automated coverage feedback within existing workflows. Coco’s instrumentation engine works across desktop, embedded, and cross-compiled environments, supporting diverse toolchains like GCC, Clang, ARM, and Green Hills. The platform helps teams meet functional safety requirements under ISO 26262, DO-178C, EN 50128, and IEC 62304, with ready-to-use qualification kits that save months of manual certification work. Its Cross-Compilation Add-on enables coverage analysis on constrained systems and microcontrollers, while the Test Center integration consolidates coverage data and test results for a unified QA dashboard. By highlighting untested logic, redundant test cases, and compliance gaps, Coco reduces testing time while increasing accuracy. Its audit-ready reports and traceable artifacts make it indispensable for industries like automotive, medical devices, rail, and aerospace. Whether running on Windows, Linux, macOS, or real hardware, Coco ensures developers know exactly what’s tested—and what’s missed. In a world where software quality and certification matter more than ever, Coco helps teams measure, optimize, and certify with confidence.
