Scott This test is specified as testset: suffix: expl nsize: {{1 2}} filter: grep -v "MPI processes" | grep -v " type:" | grep -v "Mat Object" args: -ksp_converged_reason -view_explicit_mat -pc_type none -ksp_type {{cg gmres}} test: args: -mat_type aij test: requires: hypre args: -mat_type hypre It triggers an error here https://gitlab.com/petsc/petsc/-/jobs/1519558357 <https://gitlab.com/petsc/petsc/-/jobs/1519558357>, with a CI configuration without hypre. Other testset instances works fine if any “require:" is both specified in the testset body and in the specific test. Is this supposed to work? Thanks Stefano
