HOW TO USE

  1. Compile your project to support GCOV. As a result *. gcno files will be created.
  2. Run your binaries and *. gcda files will be created.
  3. Go to a project root dir where *. gcda and *.
  4. Run lcov.bat. d:\project> d:\lcov\lcov.
  5. After execution gcov\html dir will be created with html reports for current project.

What is a LCOV file?

LCOV is a graphical front-end for GCC’s coverage testing tool gcov. It collects gcov data for multiple source files and creates HTML pages containing the source code annotated with coverage information. It also adds overview pages for easy navigation within the file structure.

How do I open an LCOV file?

This recipe assumes a basic working knowledge of Python as a language.

  1. Create a small Python script.
  2. Write first test case.
  3. Run the test case.
  4. Calculate the code coverage.
  5. Increase coverage by adding more tests.
  6. Understanding code coverage metrics.
