Testing

Tests run through CTest inside Docker.

Full suite

docker compose run --rm dev ctest --output-on-failure

Step gates

Use the -R regex from UPDATE_PLAN.md for the current step, then run the full suite before closing the step.

docker compose run --rm dev ctest -R 'elm_ae|ml_elm|h_os_elm|golden_baseline' --output-on-failure
docker compose run --rm dev ctest --output-on-failure

Test groups

Prefix	Coverage
sanity	Basic build/runtime sanity
feature_map	Map interface, additive map, identity map

solver	Batch ridge solver stability
os_elm	Online sequential learning and forgetting
os_celm	Class-distance constraint behavior
rbf_features, rbf_map	RBF utilities and map
elm_ae, ml_elm, h_os_elm	Learned feature extraction
cuda_infra, elm_gpu, gpu_ops	CUDA primitives; skip without GPU
dataset_io	Dataset loader, preprocessing, drift stream
demo_api	Demo JSON helpers and benchmark snapshot loading
golden_baseline	Numeric regression anchor

GPU tests

GPU tests must skip cleanly when no device is visible. CPU is the correctness reference for GPU comparisons.

Golden baseline

tests/test_golden_baseline.cpp records fixed-seed behavior. It is the anti-regression anchor for internal refactors.
