Steps to reproduce

$ spack install --test root netcdf-c~mpi build_system=autotools ^hdf5~mpi # ~mpi just to save time

With the head of develop, the resulting install-time-test-log.txt does not show, e.g., netcdf-c test output.

If I disable all of the installcheck() logic in the backend, install-time-test-log.txt contains check() output as expected.
