Subject [jira] [Updated] (AMBARI-8060) [Test] The framework executes the tests in random order, which makes some tests fail inconsistently
Date Tue, 04 Nov 2014 22:21:33 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-8060?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Florian Barca updated AMBARI-8060:
----------------------------------
    Attachment: AMBARI-8060.0.patch

The shuffle(tests) calls inside the unitTests.py scripts contribute to test results inconsistencies.

+ Commented the shuffle(tests) calls, to allow the test results to become predictable.
