I suggest the PETSc options database check the environmental variable
PETSC_OPTIONS_FINAL and have these values added to the options database last
(though they shouldn't overwrite values set in the code.)
I tried
$ make -f ./gmakefile test globsearch="snes_tutorials-ex69_p2p1"
EXTRA_OPTIONS="-dm_refine 5 -dm_view hdf5:$PETSC_DIR/sol.h5 -snes_view_solution
hdf5:$PETSC_DIR/sol.h5::append -exact_vec_view hdf5:$PETSC_DIR/sol.h5::append
-m 2 -n 2 -B 1"
As suggested in guide_to_stokes.md and got back
Using MAKEFLAGS: -- EXTRA_OPTIONS=-dm_refine 5 -dm_view
hdf5:/Users/barrysmith/Src/petsc/sol.h5 -snes_view_solution
hdf5:/Users/barrysmith/Src/petsc/sol.h5::append -exact_vec_view
hdf5:/Users/barrysmith/Src/petsc/sol.h5::append -m 2 -n 2 -B 1
globsearch=snes_tutorials-ex69_p2p1

So I expect there is something wrong with the tutorials on the website.
I am mystified how make test can be used to print nice output to the screen
since the tests save the output to a file and do a diff. So I would like to
know how Matt uses make test in his workflow.
