[jira] [Commented] (HADOOP-14553) Add (parallelized) integration
tests to hadoop-azure
[ https://issues.apache.org/jira/browse/HADOOP-14553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16161401#comment-16161401 ]
John Zhuge commented on HADOOP-14553:
-------------------------------------
Wow, 16 patches. Thanks [~steve_l] for the hard work! We probably all balked at the size of the patches. Promise I will play with it.
BTW, shouldn't you name "testing.md" instead of "testing_azure.md", following the example of AWS and Common?

> The Azure tests are slow to run as they are serialized, as they are all called Test* there's no clear differentiation from unit tests which Jenkins can run, and integration tests which it can't.
> Move the azure tests {{Test*}} to integration tests {{ITest*}}, parallelize (which includes having separate paths for every test suite). The code in hadoop-aws's POM &c show what to do.
> *UPDATE August 4, 2017*: Adding a list of requirements to clarify the acceptance criteria for this JIRA:
> # Parallelize test execution
> # Define test groups: i) UnitTests - self-contained, executed by Jenkins, ii) IntegrationTests - requires Azure Storage account, executed by engineers prior to check-in, and if needed, iii) ScaleTests – long running performance and scalability tests.
> # Define configuration profiles to run tests with different settings. Allows an engineer to run “IntegrationTests” with fs.azure.secure.mode = true and false. Need to review settings to see what else would benefit.
> # Maven commands to run b) and c). Turns out it is not easy to do with Maven, so we might have to run it multiple times to run with different configuration settings.
> # Document how to add and run tests and the process for contributing to Apache Hadoop. Steve shared an example at https://github.com/apache/hadoop/blob/trunk/hadoop-tools/hadoop-aws/src/site/markdown/tools/hadoop-aws/testing.md
> # UnitTests should run in under 2 minutes and IntegrationTests should run in under 15 minutes, even on slower network connections. (These are rough goals)
> # Ensure test data (containers/blobs/etc) is deleted. Exceptions for large persistent content used repeatedly to expedite test execution.
