Salutations y’all 
I recently registered a new package for testing CImGui.jl programs: ImGuiTestEngine.jl
It’s a wrapper around the upstream imgui_test_engine project. Still very new so lots of things are probably missing, feel free to open issues/PRs 
It integrates with the new renderloop in CImGui.jl v2 so there’s not too much boilerplate, and the @imcheck macro also integrates with the Test stdlib (though that could be improved).
Sneak peak of some of it being used in the CImGui.jl tests (forgive the low FPS screen recording):
