Enis Soztutar commented on HBASE-7211:
--------------------------------------
bq. => We should be able to use categories in all modules. The default should
be small; but any test manipulating the time needs to be in a specific jvm
(hence medium), so it's not always related to minicluster.
Right now, the only exception is hadoop-compat modules.

bq. => Add a chapter on flakiness.
+1.
bq. => We could actually activate the localTests profile whenever -Dtest is
used. If we do that, we can remove the reference from localTests in the doc.
+1. -PlocalTets is not intuitive, and I was burned a couple of times by this.
By having active in profile, this should be easy to do.
bq. => Integration tests are described TODO: POINTER_TO_INTEGRATION_TEST_SECTION
We can just commit HBASE-6302.
> Improve hbase ref guide for the testing part.

> Here is some stuff I saw. I will propose a fix in a week or so, please add

> ??15.6.1. Apache HBase Modules??
> => We should be able to use categories in all modules. The default should be

> ??15.6.3.6. hbasetests.sh??
> => We can remove this chapter, and the script
> The script is not totally useless, but I think nobody actually uses it.
> => Add a chapter on flakiness.
> Some tests are, unfortunately, flaky. While there number decreases, we still
> have some. Rules are:
> - don't write flaky tests! :-)
> - small tests cannot be flaky, as it blocks other test execution. Corollary:
> if you have an issue with a small test, it's either your environment either a
> severe issue.
> - rerun the test a few time to validate, check the ports and file descriptors
> used.
> ??mvn test -P localTests -Dtest=MyTest??
> => We could actually activate the localTests profile whenever -Dtest is used.
> If we do that, we can remove the reference from localTests in the doc.
> ??mvn test -P runSmallTests?? ??mvn test -P runMediumTests??
> => I'm not sure it's actually used. We could remove them from the pom.xml
> (and the doc).
> ??The HBase build uses a patched version of the maven surefire plugin??
> => Hopefully, we will be able to remove this soon :-)
> ??Integration tests are described TODO: POINTER_TO_INTEGRATION_TEST_SECTION??
> => Should be documented
