Get all SERIAL tests in Trilinos to run as 1-process tests in MPI builds
Created by: bartlettroscoe

Description:
A big problem we have with SQA and test of Trilinos is that many Trilinos packages have significant numbers of tests that only run in a non-MPI serial build (e.g. Pamgan #1415 (closed) and SEACAS #1392 (closed)). That means that running the standard CI build MPI_RELEASE_DEBUG_SHARED_PT does not run any of these tests.
This story is to create a place-marker for package-specific stories to get all of their single-process tests now running only in the non-MPI serial build to also run in the MPI builds. This way, the set of tests run in a serial build will be a strict subset of the tests run in the MPI build. Therefore, passing the MPI build will give higher confidence that the serial build will also pass all of its tests.
