Cross-population of step results and IllegalStateExceptions when running in
multi-threaded mode with multiple <webtest> tasks in the same ant file
--------------------------------------------------------------------------------------------------------------------------------------------------
Key: WT-477
URL: http://webtest-community.canoo.com/jira/browse/WT-477
Project: WebTest
Type: Bug
Versions: Future versions
Reporter: John Spann
Attachments: WebtestMulitThread.txt
When running webtest and defining wt.parallel.nbWorkers for multi-threaded
support, the resulting report summary shows the incorrect number of tests run
and individual reports are cluttered with steps from other from other tests.
Strange outputs, such as <invoke> tasks containing nested <config> tasks appear
in the report.
This is due to StepExecutionListeners created within different threads being
registered to the same parent Project. When stepResults, taskStarted, and
taskFinished events are fired, all listeners within the Project are notified,
regardless of the thread they were created within. IllegalStateExceptions
occur when a task finishes within one thread while another thread is still
within the execute method of WebTestTask, has registered its created listener
with the Project, but has not begun performing any of its TestSequence tasks
(the listener has not seen any taskStarted events).
I have attached an SVN patch to resolve the issue by explicitly associating the
StepExecutionListener to the thread it was created within. All unit and
selftests pass after this patch is applied.
Cheers,
~John Spann
