Describe the fault precisely by proposing a modification to the code. b) If possible, give a test case that does not execute the fault. If not, briefly explain why not. c) If possible, give a test case that executes the fault, but does not result in an error state. If not, briefly explain why not. d) 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. e) For the given test case below, describe the first error state. Be sure to describe the complete state. Hint: Don't forget about the program counter. source = "What is Software Testing? Why is Software Testing so important?": word - "Software": Expected = 2 f) Implement your repair and verify that the given test now produces the expected output.
