CS 351 Design of Large Programs

• .class and .java (source and compiled) in a single .jar file
• a JUnit test class
• instructions for running your example
• A screen shot of the TestRunner before (using a putInto() function that always returns true) and after completing the assignment

Part 1

1. If you put anything that's not an integer, or a String containing an integer, into the DeathBox, you die.
   Take integer to be a 32 bit java integer, and the string should be parsable using string to int (Integer.valueOf( str ).intValue())
2. If you put anything outside 6 to 60 into the DeathBox, you die.
3. If you put anything into the DeathBox that's more than three times the last thing put into the DeathBox, you die.
4. If you put the same thing into the DeathBox more than three times, you die.
5. You can't put anything into the DeathBox after you've died.
6. If the thing you put into the DeathBox doesn't cause you to die according to the rules 1-5, then you live.

Part 2

1. Create a JUnit test suite for your DeathBox Class.
2. Create individual test functions for each item in the spec
