Class DenseFloatDataSiTest

java.lang.Object
org.djunits.vecmat.storage.DenseFloatDataSiTest
public class DenseFloatDataSiTest extends Object
Unit tests for DenseFloatDataSi.

This test class verifies the complete functional behavior of DenseFloatDataSi and all default methods inherited from DataGridSi. All tests focus on correct functional semantics. If the implementation contains bugs or produces incorrect results, these tests are designed to fail.

  • All constructors (float[], float[][], Q[][])
  • Bounds checking on get(int,int)
  • All default DataGrid methods: getRowArray, getColArray
  • Copy semantics
  • Instantiations via instantiateNew
  • Cardinality behavior
  • Equality and hashCode
  • SI-conversion correctness for Q[][] (using Length)
  • Float → double copying correctness in getSiArray()
