Trying out black box testing in C
In this assignment, you will be black-box testing a few broken implementations of "isPrime". You will see that there are four broken implementations of isPrime: isPrime-broken1 isPrime-broken2 isPrime-broken3 isPrime-broken4 as well as a correct implementation: isPrime-correct All of these take one command line argument, which is the *integer* to test for primality. For example, you might run $ ./isPrime-correct 3 3 is prime $ ./isPrime-correct 4 4 is not prime Your job is to find a test case for each broken implementation which shows that it is not correct---that is, where its behavior differs from that of isPrime-correct. Note that we do not expect you to brute force this task. Think about what types of common errors could occur. For each broken program, write the input which breaks the program into a file called "input.X" where X is 1, 2, 3, or 4 (so input.1 has the command line argument that shows that isPrime-broken1 is broken). Note that isPrime-correct's behavior is considered correct, and any test case which deviates from it is considered wrong.
