	# Check that the ADTypeCheckContext works as expected.
	Test.@testset "ADTypeCheckContext" begin
	Turing.@model test_model() = x ~ Turing.Normal(0, 1)
	tm = test_model()
	adtypes = (
	Turing.AutoForwardDiff(),
	Turing.AutoReverseDiff(),
	Turing.AutoZygote(),
	Turing.AutoTracker(),
	)

#2341 gets rid of AutoTracker from this list, but doesn't add back AutoMooncake. I tried to naively add it to the list, but the tests failed.

We should either add it in, or figure out why the tests don't pass and add a note explaining it.
