Question

Multiple Choice: We have been assigned the task of developing a software testing tool (tester) that can assess reachability of statements in a program. Namely, given a program and a statement x in the program (line in the code), the tester should produce a sequence of inputs that demonstrates that the program can reach statement x, or declare that statement x is not reachable under any input sequence. What should we respond to the manager who assigned this task

Answer 1

Answer:

A. There is no algorithm to decide whether this can be done or not.

Explanation:

We should respond to the manager who assigned this task that there is no algorithm to decide whether this can be done or not. This is because there are many unknowns with the program that is provided. There are various programming languages and each one has its own structure and requirements in order to test them. Also, each function is created differently with different inputs that are necessary and different algorithms used. It is impossible to design a single algorithm that works to test every single provided program. That is why testers have to create custom test cases for each function.
