Update test_kernel_functions.jl to use get_tangent getter function
instead of direct field access to material_cache.𝔻, matching the
new AssemblyMaterialWorkspace API.
Updated compute_block! call to pass arrays directly from caches:
- geometry_cache.∇N_data
- geometry_cache.detJ_w
- material_cache.𝔻
Maintains test comparison between manual and automatic integration.
New file: test/domains/continuum/test_kernel_functions.jl
Tests for:
- ContinuumKernel construction
- compute_block_at_point (weak form at single point)
- Validates stiffness contribution at integration point
- Checks tensor dimensions and symmetry
Validates:
- Kernel properly wraps formulation and material
- compute_block_at_point produces symmetric Tensor{2,3}
- Integration point contributions are reasonable magnitude
- No NaN or Inf values
Low-level validation of the atomic weak form operation
before integration loop aggregation.
