Week 11 [Fri, Oct 23rd] - Tutorial

1. What are the equivalence partitions for the parameter day of this method?

   /**
    * Returns true if the three values represent a valid day
    */
   boolean isValidDay(int year, int month, int day) {
   
   } 
   

2. What are the boundary values for the parameter day in the question above?

3. Give 10 test inputs you would use for the parameter day in the question above.

Apply heuristics for combining multiple test inputs to improve the E&E of the following test cases, assuming all 6 values in the table need to be tested. Underlines indicate invalid values. Point out where the heuristics are contradicted and how to improve the test cases.

Suppose the Processor component of a software application is designed as follows:

If you want to provide the ability for other components to get notified when a Job is finished running, without the Processor component becoming dependent on those other components,

1. which design pattern would you use?
2. modify the above design accordingly.
