This is a simplification of the construction, although somewhat limiting (it means that the caller can't register the same file multiple times, though I stopped doing that anyways since it was causing confusion). What this more importantly _allows_ is logic on the FileTestBase child itself that's not test-specific -- in particular, autoupdate functionality which wouldn't use RUN_ALL_TESTS. --------- Co-authored-by: Chandler Carruth <chandlerc@gmail.com>
