Information is not correctly propagated through the macro `@trixi_testset`

(See [https://github.com/trixi-framework/Trixi.jl/actions/runs/26962641741/job/79556905609?pr=3065](https://github.com/trixi-framework/Trixi.jl/actions/runs/26962641741/job/79556905609?pr=3065)). In the following test, I have defined a different `volume_flux`: ```julia @trixi_testset "elixir_mhd_alfven_wave_nonperiodic.jl Float32" begin using Trixi @inline function flux_volume_combined(u_ll, u_rr, normal_direction::AbstractVector, equations::IdealGlmMhdEquations3D) flux = flux_hindenlang_gassner(u_ll, u_rr, normal_direction, equations) noncons_flux_left = flux_nonconservative_powell(u_ll, u_rr, normal_direction, equations) noncons_flux_right = flux_nonconservative_powell(u_rr, u_ll, normal_direction, equations) flux_left = flux + 0.5f0 * noncons_flux_left flux_right = flux + 0.5f0 * noncons_flux_right return flux_left, flux_right end @inline Trixi.combine_conservative_and_nonconservative_fluxes(::typeof(flux_volume_combined), equations::IdealGlmMhdEquations3D) = Trixi.True() @test_trixi_include(joinpath(EXAMPLES_DIR, "p4est_3d_dgsem", "elixir_mhd_alfven_wave_nonperiodic.jl"), l2=Float32[0.00021050235826592327, 0.0006558863204839041, 0.0002821364444400733, 0.000794748435433683, 0.0006839039307848098, 0.0006743445524692008, 0.000318156924452865, 0.0007885451771559438, 4.811726173404515e-5], linf=Float32[0.0012031070350810857, 0.004106999758487398, 0.001783097816025008, 0.004780625055122056, 0.005095902318184908, 0.003922455893839549, 0.002515549802432071, 0.004448527671538249, 0.00019839944646198146], RealT_for_test_tolerances=Float32, real_type=Float32, save_solution=nothing, analysis_callback=AnalysisCallback(semi, interval = 100, analysis_integrals = (entropy,)), volume_flux=flux_volume_combined) # Ensure that we do not have excessive memory allocations # (e.g., from type instabilities) semi = ode.p # `semidiscretize` adapts the semi, so we need to obtain it from the ODE problem. @test_allocations(Trixi.rhs!, semi, sol, 600_000) end ``` and this is where the volume flux is defined in the elixir: ```julia volume_flux = (flux_hindenlang_gassner, flux_nonconservative_powell) solver = DGSEM(polydeg = 3, surface_flux = (flux_hlle, flux_nonconservative_powell), volume_integral = VolumeIntegralFluxDifferencing(volume_flux)) ``` but it returns the following error ```julia /home/runner/work/Trixi.jl/Trixi.jl/examples/p4est_3d_dgsem/elixir_mhd_alfven_wave_nonperiodic.jl elixir_mhd_alfven_wave_nonperiodic.jl native: Error During Test at /home/runner/.julia/packages/TrixiTest/6CVoC/src/macros.jl:196 Got exception outside of a @test LoadError: UndefVarError: `flux_volume_combined` not defined Stacktrace: [1] top-level scope @ ~/work/Trixi.jl/Trixi.jl/examples/p4est_3d_dgsem/elixir_mhd_alfven_wave_nonperiodic.jl:19 [2] include @ ./Base.jl:496 [inlined] [3] trixi_include(mapexpr::typeof(identity), mod::Module, elixir::String; enable_assignment_validation::Bool, replace_assignments_recursive::Bool, kwargs::@Kwargs{save_solution::Symbol, analysis_callback::Expr, volume_flux::Symbol}) @ TrixiBase ~/.julia/packages/TrixiBase/MGeKl/src/trixi_include.jl:79 [4] trixi_include @ ~/.julia/packages/TrixiBase/MGeKl/src/trixi_include.jl:49 [inlined] [5] #trixi_include#6 @ ~/.julia/packages/TrixiBase/MGeKl/src/trixi_include.jl:86 [inlined] [6] (::Main.TestExamplesKernelAbstractions.TrixiTestModule.var"#2#5")() @ Main.TestExamplesKernelAbstractions.TrixiTestModule ~/.julia/packages/TrixiTest/6CVoC/src/macros.jl:15 [7] (::Base.RedirectStdStream)(thunk::Main.TestExamplesKernelAbstractions.TrixiTestModule.var"#2#5", stream::IOStream) @ Base ./stream.jl:1434 [8] #1 @ ~/.julia/packages/TrixiTest/6CVoC/src/macros.jl:14 [inlined] [9] open(::Main.TestExamplesKernelAbstractions.TrixiTestModule.var"#1#4", ::String, ::Vararg{String}; kwargs::@Kwargs{}) @ Base ./io.jl:396 [10] open(::Function, ::String, ::String) @ Base ./io.jl:393 [11] macro expansion @ ~/.julia/packages/TrixiTest/6CVoC/src/macros.jl:13 [inlined] [12] macro expansion @ ~/work/Trixi.jl/Trixi.jl/test/test_trixi.jl:35 [inlined] [13] macro expansion @ ~/work/Trixi.jl/Trixi.jl/test/test_kernelabstractions.jl:195 [inlined] [14] macro expansion @ /opt/hostedtoolcache/julia/1.10.11/x64/share/julia/stdlib/v1.10/Test/src/Test.jl:1582 [inlined] [15] macro expansion @ ~/work/Trixi.jl/Trixi.jl/test/test_kernelabstractions.jl:180 [inlined] [16] top-level scope @ ~/.julia/packages/TrixiTest/6CVoC/src/macros.jl:196 [17] eval(m::Module, e::Any) @ Core ./boot.jl:385 [18] macro expansion @ ~/.julia/packages/TrixiTest/6CVoC/src/macros.jl:172 [inlined] [19] macro expansion @ ~/work/Trixi.jl/Trixi.jl/test/test_kernelabstractions.jl:179 [inlined] [20] macro expansion @ /opt/hostedtoolcache/julia/1.10.11/x64/share/julia/stdlib/v1.10/Test/src/Test.jl:1582 [inlined] [21] top-level scope @ ~/work/Trixi.jl/Trixi.jl/test/test_kernelabstractions.jl:111 in expression starting at /home/runner/work/Trixi.jl/Trixi.jl/examples/p4est_3d_dgsem/elixir_mhd_alfven_wave_nonperiodic.jl:19 ``` I will define a new elixir as a workaround.
