Hi,
I've checked out at morning last updates, built the code base and run
the
tests …and there are 24 tests failures!
There are 9 tests failures in
org.apache.harmony.tests.java.nio.channels.DatagramChannelTest – I saw
these
failures before from time to time. It seems that tests depend on some
race
conditions because they may pass if I rerun them. Paulex, are these
tests
passing for you?
Mishura
the channels test cases on my workstations(yes I tried on several
machines) always pass, but it is still possible that some of them are
unstable and depend on race condition for others, I might miss to catch
them by mistake. Would you pls. give me more details about the failure?
I'll try to investigate them further. thank you.
I've run tests on Linux. They fail on the same assertion:
[junit] Testcase: testReceiveSend_Block_Normal(
org.apache.harmony.tests.java.nio.channels.DatagramChannelTest): FAILED
[junit] expected:<...> but was:<....localdomain>
[junit] junit.framework.ComparisonFailure: expected:<...> but

Stepan,
Thank you for the information.
As far as JUnit didn't print what result was expected to get I inserted
printing to the test and got the following:
Expected host: localhost.localdomain
Recieved host: localhost
Why do you expect that on Linux "localhost.localdomain" should be returned?
Well, that is because both RI/Harmony return this value on my test
machines(Redhat ES 3, Redhat 9 and latest stable Debian), and I didn't
expect this value is dependent on configuration(or Linux distribution?
), but as your test result shows, it probably does! So would you tell me
your linux distro version and configuration( for example, what it looks
like of the item on localhost in /etc/hosts)? so that I can check if
this constant value(localhost.localdomain) is platform dependent.
And I'll also look more inside to see if there can be other cause except
for the possible platform difference.
Thanks,
Stepan.
And before everything's OK, I'm fine if you choose to add
DatagramChannelTest into exclude list, by adding it to Ln.94 of
modules/nio/make/common/build.xml, just as ServerSocketChannelTest.
Sorry for the inconvenience caused.
And there are new 15 test failures. So now if I'll make a code update
or a
bug fix how I can be 100% sure that I don't do any regression?
Currently if a commit breaks the Harmony classlib build a notification
with
subject: "[continuum] BUILD FAILURE: Classlib/linux.ia32" will be send
to
harmony-commits mailing list. Is it possible to have the same for tests?
I
mean that after completing automatic build the existing classlib tests
suite
should be run. If there are failing tests then a report notification
with
corresponding subject will be send.
Thanks,
