Method Summary

private void	checkAdditionsAndRemovals(boolean daemon) Check that a host refresh detects a process addition then removal.
void	testDaemonAdditionAndRemoval() Check a daemon creation/deletion.
void	testParentChild() Check that a parent child relationship is correct.
void	testProcAdditionAndRemoval() Check a child creation/deletion.
void	testRefreshDaemon() Check that a process that becomes a daemon gets its parent id changed to 1.
void	testRefreshZombie() Check that a refresh involving a zombie is ok.
void	testRepeatedHostRefresh() Do several refreshes, check that the child is only added on the first pass; and never removed.
void	testUnattachedSingleExec() A single threaded program performs an exec, check that it is correctly tracked.

Method Detail

testRepeatedHostRefresh

public void testRepeatedHostRefresh()

Do several refreshes, check that the child is only added on the first pass; and never removed.

checkAdditionsAndRemovals

private void checkAdditionsAndRemovals(boolean daemon)

Check that a host refresh detects a process addition then removal.

testProcAdditionAndRemoval

public void testProcAdditionAndRemoval()

Check a child creation/deletion.

testDaemonAdditionAndRemoval

public void testDaemonAdditionAndRemoval()

Check a daemon creation/deletion.

testParentChild

public void testParentChild()

Check that a parent child relationship is correct.

testRefreshDaemon

public void testRefreshDaemon()

Check that a process that becomes a daemon gets its parent id changed to 1.

testRefreshZombie

public void testRefreshZombie()

Check that a refresh involving a zombie is ok. In /proc, a zombie has no child tasks. Within PS, a zombie appears as "defunct".

testUnattachedSingleExec

public void testUnattachedSingleExec()

A single threaded program performs an exec, check that it is correctly tracked.
