OpenAssetIO Test Host

A bare-bones C++ host application with OpenAssetIO as a dependency, for testing basic integration (linking, headers, etc).

Test targets are created that simply check that C++, C and Python components can be imported.

Note

This project is intended for use in CI and not used as a reference.

Getting started

This application can link against its dependent libraries, OpenAssetIO and OpenAssetIO-MediaCreation in two modes, depending on the value of the OPENASSETIOTEST_ENABLE_OPENASSETIO_SUBPROJECT and OPENASSETIOTEST_ENABLE_MEDIACREATION_SUBPROJECT CMake variables respectively - see below.

The usual CMake steps can be used to build and run the tests. Assuming the current working directory is at the root of the repository:

cmake -S . -B build
cmake --build build
ctest --test-dir build

Dependency Modes

This project has two main dependencies, OpenAssetIO and OpenAssetIO-MediaCreation. They can be discovered in two ways.

CMake Packages

When either OPENASSETIOTEST_ENABLE_OPENASSETIO_SUBPROJECT or OPENASSETIOTEST_ENABLE_MEDIACREATION_SUBPROJECT are set to OFF (which is the default if unspecified), the package will be discovered as a CMake package (find_package(...)) and so the package must be pre-built and installed into one of find_package's configured search paths.

Subprojects

When either OPENASSETIOTEST_ENABLE_OPENASSETIO_SUBPROJECT or OPENASSETIOTEST_ENABLE_MEDIACREATION_SUBPROJECTare set to ON, the package git submodule under this repository must be populated. The package will then be built as a subproject (add_subdirectory(...)) and so all its dependencies must be discoverable by CMake. See the OpenAssetIO and OpenAssetIO-MediaCreation repositories for more information.

Note

Python test targets are currently unsupported in this mode. If OPENASSETIOTEST_ENABLE_PYTHON is ON (default) then CMake will fail to configure with an error.

Development notes

This package follows the main OpenAssetIO contribution process.
