- Created unit test files for StructuralBeam, StructuralMaterial, and StructuralNode classes.
- Implemented comprehensive tests covering initialization, property validation, geometry calculations, load handling, and performance benchmarks.
- Ensured proper validation of material properties and nodal loads.
- Added tests for visual representation updates and connection type management.

…Node classes

- Created unit tests for StructuralBeam class covering initialization, geometry calculations, local coordinate systems, section property validation, end condition updates, material property updates, load consistency validation, stiffness matrix calculations, and performance benchmarks.
- Developed unit tests for StructuralMaterial class including initialization, Poisson ratio validation, material standard updates, shear modulus calculation, strength validation, and performance benchmarks.
- Implemented unit tests for StructuralNode class focusing on initialization, restraint code generation, degrees of freedom calculations, nodal load validation, visual representation updates, connection type management, and performance benchmarks.
- Added test files for each class in the appropriate directory structure.
