This test suite provides comprehensive functional coverage of:

  • All Position constructors
  • Parsing: valueOf and of
  • Reference creation, lookup, and simple offset chaining
  • Arithmetic operations: subtract(Position), add(Length), subtract(Length)
  • Display-unit propagation rules
  • Inherited operations from AbsoluteQuantity: comparisons, zero checks, interpolate, sum, mean, min, max
