From: Magnus Karlsson <magnus.karlsson@xxxxxxxxx> Declare the test names statically in a struct so that we can refer to them when adding the support to execute a single test in the next commit. Before this patch, the names of them were not declared in a single place which made it not possible to refer to them.
