Package org.djunits.quantity

Class VolumetricObjectDensityTest

java.lang.Object

org.djunits.quantity.VolumetricObjectDensityTest

class VolumetricObjectDensityTest
extends Object

VolumetricObjectDensityTest tests the VolumetricObjectDensity quantity class.

This suite verifies:

• Constructors, constants, SI behavior, copy constructor
• Parsing success and all parsing error branches
• All arithmetic operators:
  • VOD x Volume → Dimensionless
  • VOD x Area → LinearObjectDensity
  • VOD x Length → ArealObjectDensity
  • VOD ÷ LOD → ArealObjectDensity
  • VOD ÷ AOD → LinearObjectDensity
  • VOD ÷ VOD → Dimensionless
• reciprocal() → Volume
• Unit derivation behaviour: linear success + non-linear exception path
• Units registry sanity
