1) Explain what is wrong with the given code. Bescribe the fault precisely by proposing a
modification to the code.
2) If possible, give a test case that does not execute the fault. If not, briefly explain why not.
3) If possible, give a test case that exccutes the fault, but does not result in an error state. If not,
briefly explain why not.
4) If possible give a test case that results in an error, but not a failure. If not, briefly explain why
not. Hint: Don't forget about the program counter.
5) For the given test case,
6) Write the proper JUnit test methods for the previous questions.
