Example of Equivalence Partitioning (2)

  // Find the largest element in table in between the indexes from and to.
  // Return the index of this element.
  // Precondition: 0 <= from <= to <= table.Length-1
  public int FindMaxIndex<T>(T[] table, int from, int to)
    where T: IComparable<T> {

The method signature FindMaxIndex.

  • Equivalence partitions - all combinations of

    • table

      • table is empty/singular, largest element is first in table, largest element is last in table, largest element is in mid of table, all elements in table are equal

    • from and to

      • from and to are located at the boundaries of table

      • from = to

      • from = to - 1

      • from and to are not close to each other
