/**
* <pre>
* Purpose
* This test verifies the behavior of the BasicInvocationDispatcher.dispatch
* method for different values of the second byte sent on the request stream.
*
* Test Cases
* This test iterates over a set of bytes. Each byte
* denotes one test case and is defined by the variable:
* byte secondRequestByte
*
* Infrastructure
* This test requires the following infrastructure:
* 1) FakeRemoteImpl
* -implements Remote
* 2) FakeInboundRequest
* -constructor takes four parameters (first 2 bytes, method hash,
* and arguments) and writes them to request stream
* -abort method does nothing
* -checkConstraints does nothing
* -checkPermissions does nothing
* -populateContext does nothing
* -getClientHost returns local host name
* -getRequestInputStream and getResponseOutputStream methods
* return streams created in constructor
* 3) FakeServerCapabilities
* -checkConstraints method returns InvocationConstraints.EMPTY
*
* Actions
* The test performs the following steps:
* 1) construct a FakeRemoteImpl and FakeServerCapabilities
* 2) construct a BasicInvocationDispatcher, passing in the Collection of
* FakeRemoteImpl methods, FakeServerCapabilities,
* and null MethodConstraints and permission Class
* 3) construct an empty FakeInboundRequest
* 4) call BasicInvocationDispatcher.dispatch with FakeRemoteImpl,
* FakeInboundRequest, and an empty context
* 5) assert FakeInboundRequest response stream returns EOF
* 6) assert FakeInboundRequest abort method was called
* 7) for each test case the test performs the following steps:
* 1) construct a FakeInboundRequest, passing in secondRequestByte
* 2) call BasicInvocationDispatcher.dispatch with FakeRemoteImpl,
* FakeInboundRequest, and an empty context
* 3) assert IntegrityEnforcement object is added to Collection
* passed to dispatch method
* 4) assertion (secondRequestByte == 0x00 ?
* IntegrityEnforcement.integrityEnforced() :
* ! IntegrityEnforcement.integrityEnforced() )
* </pre>
