Subject [jira] [Commented] (REEF-1243) Fix StreamingRemoteManagerTest tests which get stuck in AppVeyor
Date Mon, 02 May 2016 23:16:12 GMT

    [ https://issues.apache.org/jira/browse/REEF-1243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267709#comment-15267709
] 

Mariia Mykhailova commented on REEF-1243:
-----------------------------------------

If each test separately passes and all together they fail, you need to figure out what they
share that makes them fail when executed together. For example, they could share some queue
which gets drained by first test and the following ones are left waiting for anything from
it.

> AppVeyor test runs get stuck on tests from {{StreamingRemoteManagerTest}} group:
> * https://ci.appveyor.com/project/ApacheSoftwareFoundation/reef/build/11-master/tests
- stuck on {{TestStreamingRegisterObserverByType}}
> * https://ci.appveyor.com/project/ApacheSoftwareFoundation/reef/build/13-master/tests
- stuck on {{TestStreamingCommunicationThreeNodesBoth}}
> * https://ci.appveyor.com/project/tcNickolas/reef/build/0.14.0-SNAPSHOT.25-APPVEYOR_EXP/tests
- stuck on {{TestStreamingCachedConnection}}
> I can't repro this locally. We need to investigate and fix this.
> To repro this on AppVeyor, one can add their mirror of reef to AppVeyor projects (https://ci.appveyor.com/projects/new
after you're logged in with your GitHub account), and then everything pushed to any branch
in the mirror gets executed in AppVeyor with the same settings as on main reef. It is possible
to limit the scope of tests executed by modifying {{test_script}} section. For example, to
run only O.A.R.Tests change it to:
> {noformat}
> test_script:
>   - cd .\lang\cs
>   - cmd: .\packages\xunit.runner.console.2.1.0\tools\xunit.console.exe .\bin\x64\Debug\Org.Apache.REEF.Tests\Org.Apache.REEF.Tests.dll
> {noformat}
> I haven't found a way to access machine on which tests are run directly, only via scripts
added to {{appveyor.yml}}.
> This change should also include reverting REEF-1311 (including {{StreamingRemoteManagerTest}}
tests to AppVeyor coverage again).
