Provide a separately installed OR-Tools model to compare a generic constraint solver with the native first-solution path without adding a production or default-test dependency. Use no-overlap, exact-fill, edge and equal-copy symmetry constraints, validate placements independently, and record model size, memory, worker count and timings for orders 8 and 9. Keep the tool only as a reference and defer DLX absent new evidence. Tests: Release CTest (9 passed) Tests: Python reference tests and compilation checks Tests: independently validated CP-SAT orders 8 and 9 Refs: #5

# Testing
|
|
|
|
The default test suite is deterministic and has no elapsed-time assertions.
|
|
Configure a build, compile it, and run the tests with CTest:
|
|
|
|
```sh
|
|
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
|
|
cmake --build build
|
|
ctest --test-dir build --output-on-failure
|
|
```
|
|
|
|
The tests independently check board dimensions, square multiplicities, bounds,
|
|
overlap, and complete coverage. They cover small unsatisfiable solver inputs, a
|
|
known order-8 solution, invalid placement diagnostics, and construction of an
|
|
order-9 solution from the order-8 fixture. The routed order-9 solver test
|
|
checks that its search counters exactly match order 8. The rendering test also
|
|
formats the known order-8 solution and checks the resulting grid dimensions and
|
|
coverage.
|
|
|
|
When Python is available, `reference-support` also tests the dependency-free
|
|
placement JSON validator. If the optional OR-Tools package is present, it
|
|
additionally builds and solves the trivial order-1 CP-SAT model; otherwise that
|
|
part is skipped without changing the default test result.
|
|
|
|
## Debug and sanitizers
|
|
|
|
Use a separate build directory for each configuration:
|
|
|
|
```sh
|
|
cmake -S . -B build-debug -DCMAKE_BUILD_TYPE=Debug
|
|
cmake --build build-debug
|
|
ctest --test-dir build-debug --output-on-failure
|
|
|
|
cmake -S . -B build-asan -DCMAKE_BUILD_TYPE=RelWithDebInfo \
|
|
-DCMAKE_CXX_FLAGS="-fsanitize=address -fno-omit-frame-pointer" \
|
|
-DCMAKE_EXE_LINKER_FLAGS="-fsanitize=address"
|
|
cmake --build build-asan
|
|
ctest --test-dir build-asan --output-on-failure
|
|
|
|
cmake -S . -B build-ubsan -DCMAKE_BUILD_TYPE=RelWithDebInfo \
|
|
-DCMAKE_CXX_FLAGS="-fsanitize=undefined -fno-omit-frame-pointer" \
|
|
-DCMAKE_EXE_LINKER_FLAGS="-fsanitize=undefined"
|
|
cmake --build build-ubsan
|
|
ctest --test-dir build-ubsan --output-on-failure
|
|
```
|
|
|
|
The sanitizer flags shown are supported by Clang and GCC. Other compilers may
|
|
require different flags. A feasible solver run currently exposes the
|
|
pre-existing defect tracked by issue #14; the test additions deliberately do
|
|
not include its separate fix.
