/*
 * Test Helper
 * This header includes all kinds of helpers for testing. It tries to include
 * everything required and provides simple macros to avoid duplicating code in
 * each test. We try to keep tests as small as possible and move everything that
 * might be common here.
 *
 * We avoid sticking to our usual coding conventions (including headers in
 * source files, etc. ..) and instead make this the most convenient we can.
