# Tests for smartbotic-database

# yyjson (v1.10+) — Phase A swaps nlohmann::json::parse for parse_to_nlohmann
# at hot paths in wal.cpp, snapshot.cpp, history_store.cpp, etc. Any test
# target that compiles those files now also needs json_parse.cpp linked and
# yyjson linked. Resolve once at file scope so every test target below can
# use ${yyjson_LIBRARIES} / ${yyjson_INCLUDE_DIRS}.
