Objectives After completing this lab you should be able to: find errors in someone else's code Step 1: Create a New BlueJ Project Step 2: Download Debugging.java We created a class with several methods that have some devious bugs! Create a new class called Debugging and delete all of the starter code. Cut and paste the provided code from (Debugging.java) into the newly created class. It should compile with no errors. Step 3: Create a new class called DebuggingTest Copy the main ) provided in Debugging.java to get you started. Read what each method is supposed to do and then write test cases for each (except for getInventory). Write one test case for each of the constructors and setInventory(). Write TWO test cases for the remaining five methods. However, caughtSpeeding () should have four tests. Therefore, your test harness should have fifteen tests
