Hi,
I'm running an integration test using the CamelSpringJUnit4ClassRunner to
test a route JMS -> Processor -> SFTP endpoint. In my test, I use a
ProducerTemplate to fire a message to the JMS endpoint and mock the SFTP
endpoint where I assert sftpMockEndpoint.setExpectedMessageCount(1). This
all works fine.
I've now written a test where I send an invalid message to the JMS queue.
Normally this is caught by the processor which logs the message and stops
any further processing. The SFTP endpoint should not receive a message in
this case, so I've added:
sftpMockEndpoint.setExpectedMessageCount(0)
When I run this test and pass in a valid message (i.e. one that reaches the
SFTP endpoint), I'm still getting a positive result - the SFTP endpoint
receives a message AND the setExpectedMessageCount(0) assertion passes.
I believe that because the JMS queue is asynchronous, the assertions are
being fired before the message has passed along the route - is this
correct? E.g.:
1. set mock expectation sftpMockEndpoint.expectedMessageCount(0);
2. fire message to JMS queue. Starts an async process and return control to
test method
3. test method runs sftpMockEndpoint.assertIsSatisfied(); which asserts that
the SFTP mock has received no messages. Assertion is correct.
4. JMS messages continues to be processed and eventually makes it's way to
the SFTP mock, which results in 1 message being received after the test
assertions have been processed.
Please could you confirm if this is the case and if there is anything I can
do to suspend processing of the assertions until the message has gone all
the way through the route? I tried adding a
sftpMockEndpoint.whenAnyExchangeReceived(new Processor() { // throw
Exception }); to trigger a failure in the test whenever the SFTP mock
received an Exchange but unfortunately the Exception gets swallowed up by
the test framework.
The only solution I have found is to add a Thread.sleep(100); before the
test assertions (assertIsSatisfied) are processed, but this is ugly and I
don't want arbitrary sleeps within my code.
Any help would be greatly appreciated and apologies for the length of this
post - I wanted to include as much information as possible but not post
great swathes of unintelligible code.
Thanks again,
John
