[jira] Commented: (HADOOP-6971) Clover build doesn't generate per-test coverage

["Konstantin Boudnik (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-6971?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12914610#action_12914610 ] 

Konstantin Boudnik commented on HADOOP-6971:
--------------------------------------------

Code coverage reports provided by Clover runs (e.g. [here|https://hudson.apache.org/hudson/view/Hadoop/job/Hadoop-Common-trunk/clover] show the information about covered classes, methods, and so on.
However, no tests info is shown. It simply says 
{noformat}
Test Results   0 / 0 tests 0 secs
No test results could be found. Please ensure that you have instrumented your unit tests correctly.
{noformat}

Apparently, Clover can't find and instrumented any tests classes in the source code. 
Same issues is found in HDFS and MR.

> Because of the way the structure of Hadoop's builds is done Clover can't properly detect test classes among the sources. As the result clover reports are incomplete and do not provide viral per-test coverage info.
