## What it is
LCOV is a set of Perl scripts that capture, manipulate, and visualize code coverage data from tools like gcov, llvm-cov, Coverage.py, Cobertura, and others. It generates hyperlinked HTML coverage reports with bar graphs and hierarchical views suitable for large projects.

## Use cases
- generate html coverage reports for c/c++ projects
- measure linux kernel code coverage
- convert coverage.py output to lcov format
- track differential coverage across builds
- browse test coverage of a large codebase by directory

## When to choose
- you need rich HTML coverage reports for gcov or llvm-cov data
- you work on large projects needing hierarchical coverage browsing
- you need to unify coverage data from multiple languages

## When to avoid
- you want a native library API for coverage data rather than CLI tools
- you need coverage for languages with no supported coverage tool

## Facets
- artifact type: cli-tool
- maturity: active
- function: testing, developer-tools, documentation
- domain: testing, developer-tools
- platform: cli, cross-platform
- tags: code-coverage, gcov, html-report, coverage-reporting, perl, command-line, linux
