Package org.djunits.quantity

Class VolumeTest

java.lang.Object
org.djunits.quantity.VolumeTest
class VolumeTest extends Object
VolumeTest tests the Volume quantity class.

This test suite verifies:

  • Constructors, constants, copy behavior, and SI conversions
  • Class-specific String parsing behavior (success + error branches)
  • Arithmetic operations producing correct result quantities
  • Unit conversions for SI, SI-derived, imperial/US customary, and astronomical units
  • Unit derivation behavior (linear + non-linear exception path)
  • Units registry resolution sanity
