Problem:

julia> SparseDiffTools.__test_backend_loaded(ADTypes.AutoForwardDiff())
ERROR: AutoForwardDiff{nothing, Nothing}(nothing) requires ForwardDiff.jl to be loaded. Please load it.

Solution: edit the following lines to add the ReverseDiff case https://github.com/JuliaDiff/SparseDiffTools.jl/blob/d2f35b7b11371021587e0d5eb34f417405b144b5/src/highlevel/common.jl#L344-L355
