Constructor Summary

TrackingDatabaseTest()

Method Summary

void	acquireReleaseLock() Check that acquire/release lock correctly encode the id values.
void	addRemoveListener() Test that the add/remove of listeners is correctly passed through.
void	doubleAddListener() Test that if a listener is added twice an error is generated.
void	getObjectTest()
void	idClearCalled() Check that if a reference is cleared by the client, the gc event is captured and the database passes on a refereceCleared event to the lower levels.
void	idStillTrackedNoClearCalled() Check that if the returned reference is held by the caller, it is not removed from the active pool.
void	illegalClientSideID() Test to ensure that passing in normal ids into the TrackingDatabase by higher levels generates an error.
void	illegalReferenceCleared() Test to ensure an exception is thrown if a higher up class calls referenceCleared(), all reference tracking is managed by the TrackingDatabase.
void	illegalTypeReturn() Ensure that the underlying database cannot accidently return tracked ids.
void	listenerTest() Test that the listener notications are passed through and translated.
void	nullRootGet() Check that a getRoot that contains null works correctly.
void	nullRootSet() Test that a setRoot(X,null) works correctly.
void	setRootIfNull() Check that setRootIfNull correctly encodes and decodes fields
void	setUp() Pre-test setup.
void	syncObject() Check the synchronizeObject correctly encodes and decodes the request fields.
void	tearDown() Post test cleanup
void	typeRequestTest() Test that type request/responses are correctly encoded and decoded.
void	validSetRootTest() Test that the setRoot call correctly encodes/decodes ids.

Method Detail

setUp

public void setUp()

tearDown

public void tearDown()

Post test cleanup

idClearCalled

public void idClearCalled()
                   throws java.lang.InterruptedException

Throws:

java.lang.InterruptedException - On wait error.

illegalClientSideID

public void illegalClientSideID()

Test to ensure that passing in normal ids into the TrackingDatabase by higher levels generates an error.

nullRootGet

public void nullRootGet()

Check that a getRoot that contains null works correctly.

nullRootSet

public void nullRootSet()

Test that a setRoot(X,null) works correctly.

illegalReferenceCleared

public void illegalReferenceCleared()

Test to ensure an exception is thrown if a higher up class calls referenceCleared(), all reference tracking is managed by the TrackingDatabase.

validSetRootTest

public void validSetRootTest()

Test that the setRoot call correctly encodes/decodes ids.

typeRequestTest

public void typeRequestTest()

Test that type request/responses are correctly encoded and decoded.

listenerTest

public void listenerTest()

Test that the listener notications are passed through and translated.

illegalTypeReturn

public void illegalTypeReturn()

Ensure that the underlying database cannot accidently return tracked ids.

getObjectTest

public void getObjectTest()

idStillTrackedNoClearCalled

public void idStillTrackedNoClearCalled()
                                 throws java.lang.InterruptedException

Check that if the returned reference is held by the caller, it is not removed from the active pool.

Throws:

java.lang.InterruptedException - On wait error.

acquireReleaseLock

public void acquireReleaseLock()
                        throws java.lang.InterruptedException

Check that acquire/release lock correctly encode the id values.

Throws:

java.lang.InterruptedException

setRootIfNull

public void setRootIfNull()

syncObject

public void syncObject()

Check the synchronizeObject correctly encodes and decodes the request fields.

doubleAddListener

public void doubleAddListener()

Test that if a listener is added twice an error is generated. A Database only supports one listener for a given client at a time.

addRemoveListener

public void addRemoveListener()

Test that the add/remove of listeners is correctly passed through.
