/**
* <pre>
* Purpose
* This test verifies the behavior of the UuidFactory.read method.
*
* Test Cases
* This test iterates over a set of long value pairs. Each pair
* denotes one test case and is defined by the variables:
* long mostSig
* long leastSig
*
* Infrastructure
* This test requires no special infrastructure.
*
* Actions
* The test performs the following steps:
* 1) call the UuidFactory.read method with null
* and assert a NullPointerException is thrown
* 2) for each test case, performs the following steps:
* 1) copy mostSig and leastSig to a byte array in the appropriate
* format for UuidFactory.read
* 2) construct a ByteArrayInputStream with the byte array
* and pass it to UuidFactory.read
* 3) verify the returned Uuid contains the correct values
* </pre>
