-# Topology and Integration Standalone Tests (test/topology/)
-
-## What
-Standalone validation of topology and integration modules WITHOUT loading full JuliaFEM.
-Tests all 17 topology types and Gauss quadrature integration for 1D, 2D, and 3D elements.
-
-## Why
-**Standalone testing** avoids name conflicts with old basis system during the transition period.
-This allows us to validate the new zero-allocation topology/integration infrastructure
-independently of the legacy Element and Problem systems.
-
-Validates fundamental properties:
-- **Node counts**: Each topology has correct number of nodes (Tri3=3, Tet4=4, Hex8=8, etc.)
-- **Dimensionality**: dim() returns 1, 2, or 3 correctly
-- **Reference coordinates**: Standard parametric domain ([0,1] for simplices, [-1,1] for tensor products)
-- **Connectivity**: edges() and faces() return correct tuple-based connectivity
-- **Integration weights**: Gauss quadrature weights sum to reference element volume/area
-
-**This is core infrastructure** - if this fails, everything else will fail!
-
-## How
-**Topology Tests** (src/topology/*.jl):
-- Seg2, Seg3: 1D line elements (2 and 3 nodes)
-- Tri3, Tri6, Tri7: 2D triangle elements (linear, quadratic, cubic)
-- Quad4, Quad8, Quad9: 2D quadrilateral elements
-- Tet4, Tet10: 3D tetrahedral elements
-- Hex8, Hex20, Hex27: 3D hexahedral elements
-- Pyr5: 3D pyramid element
-- Wedge6, Wedge15: 3D wedge/prism elements
-
-For each: Tests `nnodes()`, `dim()`, `reference_coordinates()`, `edges()`, `faces()`
-
-**Integration Tests** (src/integration/*.jl):
-- IntegrationPoint{N} struct with ξ coordinates and weight
-- integration_points(Gauss{order}, topology) for all combinations
-- Validates weights sum to reference element volume:
-  - Tri3: 0.5 (half unit square)
-  - Quad4: 4.0 ([-1,1]²)
-  - Tet4: 1/6 (tetrahedron volume)
-  - Hex8: 8.0 ([-1,1]³)
-
-## Expected Results
-- ✅ All 17 topology types instantiate correctly
-- ✅ Node counts match specification
-- ✅ Reference coordinates within parametric domain
-- ✅ Edge/face connectivity returns NTuple (zero-allocation)
-- ✅ Integration weights sum to reference volume (tolerance 1e-10)
-- ✅ Higher Gauss orders provide more integration points
-- ✅ Zero allocations for tuple-based API
-
-## Test Strategy
-**Standalone execution**: Manually includes source files to avoid JuliaFEM module loading.
-This is TEMPORARY during transition. Once name conflicts resolved, will use normal
-`using JuliaFEM` pattern.
-
-## Files Tested
-- src/topology/: 17 topology files (seg2.jl through wedge15.jl)
-- src/quadrature/: Low-level quadrature data (quaddata.jl, gltri.jl, glquad.jl, gltet.jl)
-- src/integration/: High-level integration API (integration.jl, gauss.jl)
