------------------------------------------
Summary: [test] one_router test_48 ConnectionUptimeLastDlvTest
intermittent fail
Key: DISPATCH-1607
URL: https://issues.apache.org/jira/browse/DISPATCH-1607
Project: Qpid Dispatch
Issue Type: Bug
Components: Tests
Affects Versions: 1.10.0
Reporter: Charles E. Rolke
Fix For: 1.12.0
This test fails with a dubious indication that delivery arrived before a
predicted delivery time.
There is some uncertainty with respect to the test timing declarations based on
event.reactor.schedule calls with integer timing granularity and the connection
statistics gathered with Node queries, also with integer timing granularity.
If the connection takes only a few hundred microseconds to start up then the
router's internal uptime and last delivery times may appear to be a full second
behind the test times. The router uptime may be 1.999900 S and the external
test expects >= 2.000000 S and so the test fails. This is normal for systems
where the times are rounded down to the nearest whole second.
The fix for this test is to relax the timing limits by one second.
