/**
|
|
* The test for the implementation of an object of the type <BR>
|
|
* ThreadGroupReference. <BR>
|
|
* <BR>
|
|
* The test checks up that results of the method <BR>
|
|
* <code>com.sun.jdi.ThreadGroupReference.threads()</code> <BR>
|
|
* complies with its spec. <BR>
|
|
* <BR>
|
|
* The case for testing includes two ThreadGroup objects defined <BR>
|
|
* in a debuggee and their mirrors in a debugger. <BR>
|
|
* Parenthood relationships between the objects are as follows: <BR>
|
|
* threadGroup2 is a subgroup of mainParent <group> <BR>
|
|
* The objects are created together with three debuggee's threads; <BR>
|
|
* the main thread and a thread2 belong to the mainParent group, <BR>
|
|
* whereas a thread3 to the subgroup. <BR>
|
|
* The test works as follows. After being started up, <BR> <BR>
|
|
* the debuggee creates a 'lockingObject' for synchronizing threads, <BR>
|
|
* enters a synchronized block in which it creates two new threads, <BR>
|
|
* informs the debugger of the threads creation, <BR>
|
|
* and is waiting for reply. <BR>
|
|
* Since the threads use the same locking object in their 'run' methods <BR>
|
|
* they are locked up until main thread leaves the synchronized block. <BR>
|
|
* Upon the receiption a message from the debuggee, <BR>
|
|
* the debugger gets Lists of threads in each of the groups, <BR>
|
|
* and checks up the sizes of Lists and names of ThreadReference objects<BR>
|
|
* in the List returned by the tested method, <BR>
|
|
* that is, mainParent.threads(). <BR>
