C++ Testing

This file extends common/testing.md with C++ specific content.

Framework

Use GoogleTest (gtest/gmock) with CMake/CTest.

Running Tests

bash

cmake --build build && ctest --test-dir build --output-on-failure

Coverage

bash

cmake -DCMAKE_CXX_FLAGS="--coverage" -DCMAKE_EXE_LINKER_FLAGS="--coverage" ..
cmake --build .
ctest --output-on-failure
lcov --capture --directory . --output-file coverage.info

Sanitizers

Always run tests with sanitizers in CI:

bash

cmake -DCMAKE_CXX_FLAGS="-fsanitize=address,undefined" ..
