Downstream propagator projects can use Gecode's test harness through installed libraries and headers. The harness provides registration, a runner, and helpers for integer/Boolean, set, and float tests, with set and float support following the configured variable modules.
The libraries follow Gecode's shared/static build options in CMake and Autoconf. CMake exports the
testcomponent andGecode::gecodetest,Gecode::gecodetestint,Gecode::gecodetestset, andGecode::gecodetestfloat, with dependencies on matching library variants. Gecode's own test executable uses the same libraries.Failure diagnostics include an exact
-replaycommand for the failing iteration. The guide covers independent solution oracles, common variable domains, the controls available to each family, and installed-package consumption. The changelog records the feature for Gecode 6.5.0.Validation includes public smoke tests, exact seed replay, full shared installations through CMake and Autoconf, an integer-only static installation, and installed consumers using CMake and direct compiler linking. The CI matrix also checks the public smokes and an installed consumer in Windows shared and static builds.
