name: CI C++ Tests

# Builds the Catch2 suite and runs it. Nothing else in CI does: the packaging
# workflows and the -Werror job all configure with BUILD_TEST_SUITE off, so
# tests/ could stop compiling and no job would notice.
#
# Pinned to ubuntu-24.04 rather than ubuntu-latest because the suite needs
# Catch2 v3, which is what noble packages. An older image ships v2, where the
# v3 spellings the tests use (catch2/catch_all.hpp, Catch::Approx,
# Catch2::Catch2WithMain) do not exist.

      # Run the binary rather than ctest. Two reasons: the [notCI] tag marks the
      # cases that need a reachable database or a listening socket, and
      # catch_discover_tests does not carry Catch2 tags through as ctest labels,
      # so ctest has no way to skip them. And zm_font.cpp loads its fixtures by
      # relative path, so the working directory has to be the one the build
      # copied tests/data into.
