Question
The following method has a fault in the for statement that causes the method to skip the 0th element. The test should use “>=”, so an error state is created when i reaches 0. public static int findLast (int[] L, int e) { for (int i=L.length-1; i > 0; i--) { if (L[i] == e) return i; } return -1; }
Design four tests with the following characteristics:
- does not reach the fault
- reaches the fault but does not infect
- reaches the fault, infects, but does not fail
- reaches, infects, and fails
