1. Explain what is wrong with the given code. Describe 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 executes 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: Dont forget about the program counter.
5. For the given test case below, describe the first error state. Be sure to describe the complete state. Hint: Dont forget about the program counter.

source = "What is Software Testing? Why is Software Testing so important?"; word = "Software"; Expected = 2

6. Implement your repair and verify that the given test now produces the expected output. Submit a screenshot demonstrating your new program works.

** Counts the number of occurrence of a substring in another string * @param source string to use as a source of the match * @param word string which is a substring of the source @return number of occurrences of word in source * @throws NullPointerException if source is null wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww private static int countOccurrence (String source, String word) { String[] temp = source:split(" "); int count = 0; for (String str : temp) { if (word == str) { count++; } } return count; } // Test: // source = "What is Software Testing? Why is Software Testing so important?", // word = "Software"; // Expected = 2
