[jira] Created: (QPID-1640) Improve existing/add more failover
tests
Improve existing/add more failover tests
----------------------------------------
Key: QPID-1640
URL: https://issues.apache.org/jira/browse/QPID-1640
Project: Qpid
Issue Type: Improvement
Components: Java Client
Affects Versions: M5
Reporter: Rajith Attapattu
Assignee: Rajith Attapattu
Fix For: M5
It would be good to build a few more tests on top of the current FailoverTests.
One idea is to send/receive a certain amount of messages then failover and then send/receive the rest of the messages and verify the order of messages and the count.
Another idea is to failover in loop between two brokers while maintaining the same session while doing the above in each iteration.

Rajith Attapattu updated QPID-1640:
-----------------------------------
Attachment: QPID_1640.patch
This patch contains improvements made to the existing failover test cases.
It also adds a new test case for produce x messages, consume y (<x) messages, do failover and then produce p and try to consume (x-y + p) messages.
1.The tests are using sync_publish='all' and sync_ack='true' to weed out duplicates. Since we control the broker shutdown we can prevent the corner case where the "last message sent or the last messaged acked could be in doubt".
2. The transacted version of the above test is currently disabled as the cluster does not do full session resume yet.
3. A another test case to be added is to run the above usecase in a loop by rotating failover between the two brokers.
4. The x to produce (out of total messages) and y to consume before failover is determined by a random number generator with a given seed. The seed and the iterations for the loop could be configured using the system properties defined in cpp.cluster.testprofile
5. The default seed will generate the following pattern for the test case that runs in a loop.
Produce 6 consume 4
Produce 3 consume 2
Produce 4 consume 3
Produce 1 consume 1
Produce 4 consume 1
Produce 3 consume 1
Produce 6 consume 6
Produce 3 consume 3
Produce 7 consume 3
Produce 4 consume 1

[jira] Resolved: (QPID-1640) Improve existing/add more failover

Rajith Attapattu resolved QPID-1640.
------------------------------------
Resolution: Fixed
A modified version of this patch was committed at rev 750203 in Qpid trunk.
There were several updates to the test after that by me and Martin.
I have also added python based test framework that could test failover more thoroughly using the brokertest.py (multi broker framework introduced by alan conway).
These tests use the failover exchange and also test failover while producer and consumer are in progress.
This improvement was added in rev 834724 in Qpid trunk with subsequent improvements.
