What problem does it solve?

This Skill helps developers instrument C/C++ projects with gcov to measure test coverage, allowing teams to identify untested code paths and improve testing efficiency.

Core Features & Use Cases

  • Instrumentation: Enable coverage data collection by compiling with --coverage flags (CFLAGS/LDFLAGS) and producing .gcda/.gcno files.
  • Reporting: Generate per-file reports with gcov and aggregate HTML reports with gcovr.
  • Use Case: A team wants to increase line and branch coverage across a large codebase by iteratively adding tests until coverage improves.

Quick Start

Build with coverage: gcc --coverage -o program source.c Run program: ./program Generate per-file report: gcov source.c Create HTML coverage: gcovr --html-details -o coverage.html
