Binary Search In Java Test

Here are some test cases for BinarySearchInJava. In order to pass the search must be capable of determining whether a value is in the array, returning an index to the value if it is, and throwing an exception when asked to return an index to a value that is not in the array. I am interested in what XP might consider to be a proper set of tests for this. -- PhilGoodwin

           new BinarySearchTest("not in array")
