Path Instrumentation 1 in Software Testing

Path Instrumentation

Path instrumentation confirms that the outcome was achieved by the intended path

The displayed image is an example of a routine for the assumed input value x=4

If it yields the same output y=5 for all the case statements then it said to be co-incidental correctness

Otherwise it detects a bug

Co-incidental Correctness: The co-incidental correctness stands for achieving the desired outcome for wrong reason

The above image is an example of a routine, for the (unfortunately) chosen input value (X=16), yields the same outcome (y=2), no matter which case we select

Therefore, the tests chosen this way will not tell us whether we have achieved coverage

For example, the five cases could be totally jumbled and still the outcome would be the same
