To run @report_opt I had to modify the test from here to look like

module Williamsom2ThetaMethodFullNewtonTests

using Test
using Gridap
using GridapGeosciences
using SparseMatricesCSR

# Solves the steady state Williamson2 test case for the shallow water equations on a sphere
# of physical radius 6371220m. Involves a modified coriolis term that exactly balances
# the potential gradient term to achieve a steady state
# reference:
# D. L. Williamson, J. B. Drake, J. J.HackRüdiger Jakob, P. N.Swarztrauber, (1992)
# J Comp. Phys. 102 211-224

Executing @report_opt Main.Williamsom2ThetaMethodFullNewtonTests.test() then generated the attached file.
