# gcovr configuration for Cockatrice line coverage.

# Used by .ci/compile.sh --coverage and by hand:
#
#   cmake -S . -B build/cover -DCMAKE_BUILD_TYPE=Debug -DWITH_SERVER=1 -DTEST=1 -DENABLE_COVERAGE=ON
#   cmake --build build/cover -j 24
#   ctest --test-dir build/cover -LE bench -j 24
#   gcovr build/cover --root . --object-directory build/cover --txt --decisions

# The point of most of this file is subtraction. A raw report is dominated by code no test can
# reach: vendored third-party trees, build directories left over from earlier experiments, and
# the client's main() and window classes, which have no headless test. Those all dilute the one
# number worth watching, so they are filtered out here rather than in every invocation.

# root is deliberately not set here. This file is normally invoked from the build directory
# (compile.sh runs there, because it configures with `cmake ..`), so a `root` of `.` would
# resolve to the build tree and every filter below would exclude everything. compile.sh passes
# --root explicitly instead.

# Our own code only. This keeps generated Qt MOC output, protobuf output and anything CMake
# built under the source tree out of the report.

# The tests are the vehicle, not the subject. They are compiled with the same instrumentation,

# it. Helpers under tests/ are excluded on the same grounds.

# the total down by a fixed amount that hides movement in the code we can actually test. The

# there, which is where most of its line count lives.
