Exercise 10:(3) ModifyMusic5.javaby adding aPlayableinterface. Move theplay( )declaration fromInstrumenttoPlayable. AddPlayableto the derived classes by including it in theimplementslist. Changetune( )so that it takes aPlayableinstead of anInstrument.


An example of a Test Plan You should include tests for: · all conditions of normal use · fielded error conditions (those that are reported by the program and program continues) · fatal error conditions (those that cause the program to stop) Please keep test plans as separate documents rather than as inline code. This is an example a test plan for Program 2 TME1. It is not necessarily complete or the only way you can lay this out. It illustrates one way to show how you will test a program, why, and the expected results. Testing normal conditions > java SubString qwerty 2 3 resulting string is: ert > java SubString qwerty 0 1 resulting string is: q > java SubString qwerty 0 6 resulting string is: qwerty Testing error conditions in the two arguments > java SubString qwerty 1 8 resulting string is: error - arguments out of range > java SubString qwerty -1 3 resulting string is: error - arguments out of range > java SubString qwerty 0 g resulting string is: error - arguments non numeric Testing error conditions with insufficient arguments > java SubString insufficient arguments please use SubString > java SubString qwerty insufficient arguments please use SubString > java SubString qwerty 2 insufficient arguments please use SubString If you have no input but use built in tests these should also cover all possible conditions and indicate the purpose of the tests in the output to the console. If you are testing a GUI program you should also include details of the tests you have done - and why, indicating the sequence of events and maybe a screen print of the result.
