addBook test To test this class the Book class will need to be completed. 1. Add a Book to the Reader and check the status code. 2. The first time the book is added an assertEquals(reader.addBook (book), Code. SUCCESS) will pass 3. A second attempt to add the book will result in assertNotEquals passing when compared to a Code. Success 4. A second attempt to add the book will result in assertEquals passing when compared to Code. BOOK_ALREADY_CHECKED_OUT_ERROR; getBookCount_Test To test this class the Book class will need to be completed. 1. Create a Reader object. a. Assert that book count is 0 2. Add a Book to the Reader object a. Assert that book count is 1 3. Remove a Book from the Reader a. Assert that bookCount is O hasBook test 1. Create a Book 2. Use hasBook to check if the Reader has the book, should return false a. assertFalse should pass 3. Use addBook to add the book to the Reader 4. hasBook should now return true a. assert True should pass removeBook test 1. Ensure that assertEquals passes when compared to Code. READER_DOESNT_HAVE_BOOK_ERROR before a Book is added 2. Add a book 3. Ensure that assertEquals passes when compared to when Code. SUCCESS removing the
