	 * This test ensures that APIs are discovered / registered / called.
	 *
	 * It was introduced after {@since N°6436} when some APIs registration in \MetaModel::InitClasses() were lost during a merge {@link https://github.com/Combodo/iTop/commit/6432678de9f635990e22a6512e5b30713c22204a#diff-c94890a26989b5a5ce638f82e8cc7d4c7aa24e6fbb9c2ca89850e8fa4e0e9adaL3004} preventing them from being called when requested. This was hard to detect as it needed an extension to use the lost API to witness that it was no longer called.
	 *
	 * For each new API, a new test case should be added here to ensure that we don't lose it later.
	 * To do so:
	 * - Add the API to the provider
	 * - Add a class extending / implementing the API in ./Delta/application-extension-usages-in-snippets.xml
	 *
	 * @return void
