Assignment
Rather than writing a complete method and then testing it, test-driven development involves writing the tests and the method in parallel. The sequence is as follows:
• Write a test case for a feature.
• Run the test and observe that it fails, but other tests still pass.
• Make the minimum change necessary to make the test pass.
• Revise the method to remove any duplication between the code and the test.
• Rerun the test to see that it still passes.
We then repeat these steps adding a new feature until all of the requirements for the method have been implemented.
We will use this approach to develop a method to find the first occurrence of a target in an array.
Case Study: Test-Driven Development of ArraySearch.search
Write a program to search an array that performs the same way as Java method ArraySearch.search. This method should return the index of the first occurrence of a target in an array, or -1-1 if the target is not present.
We start by creating a test list like that in the last section and then work through them one at a time. During this process, we may think of additional tests to add to the test list.
Our test list is as follows:
1. The target element is not in the list.
2. The target element is the first element in the list.
3. The target element is the last element in the list.
4. There is more than one occurrence of the target element and we find the first occurrence.
5. The target is somewhere in the middle.
6. The array has only one element.
7. The array has no elements.
Format your assignment according to the following formatting requirements:
1. The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.
2. The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
3. Also include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
