如何使用介子在 C++ 中执行代码覆盖？

Question

I'm using meson and ninja as build system in my C++ project and I've configured catch2 as testing framework. I was wondering how to perform code coverage with the tests that I've written. I read this page, https://mesonbuild.com/Unit-tests.html but seems pretty unclear to me, can anybody help?

Answer 1

You should use one of coverage related targets: coverage-text , coverage-html , coverage-xml as described here . Or just coverage that tries all of these if possible:

$ ninja coverage -C builddir

Results are written to ./builddir/meson-logs directory.

Note that to produce html coverage reports you need lcov and genhtml binaries which are installed by lcov package.
