Every test had the same pattern of a main catching exceptions and returning 0 or 1 based on that. Factor that into test.hpp. As most code in test.hpp is only executed on failure and those should not occur this file is excluded from coverage. Finally test.hpp is included last and the header to test first consistently to check for self-sufficient includes.
