Suppose you want to perform basic path testing and D-U path testing for the Java program given that calculates the Hotel Suites occupancy. These are located on floors 10-16. There is no 13th floor. a) Draw the control flow graph and design test cases to perform basic path testing Submit: clearly labeled control flow graph and test cases b) Implement Junit code to run test cases for each path. Do you get the desired output? Use eclEmma and report the code coverage of your tests. Submit: your Junit test program and a screenshot of code coverage using eclEmma. c) Now design test cases for D-U path testing for variables occupancyRate and totalOccupied. Submit: clearly labeled D-U graph and test cases for both variables above. d) Identify bugs in the program using test cases b and c above and fix them Submit: correct program
