This will not be done in Arquillian Core for sure since it is totally out of scope of Arquillian Core itself. It could be however implemented in upcomming reporting / logging extension https://github.com/smiklosovic/arquillian-unified-recorder

However, this will be actual when 8 will come out [WFLY-280] Provide an operation to retrieve the last 10 errors from the log - JBoss Issue Tracker
The problem with the pull request for [WFLY-280] Provide an operation to retrieve the last 10 errors from the log - JBoss Issue Tracker is that it is an extension of jboss-cli, so it does not provide an API that can be easily called within your application. Finally, I found a suitable tool for obtaining of messages from the server log. It is called Splitlog: http://triceo.github.io/splitlog/. I have successfully used it together with Arquillian. I just used ShrinkWrap resolver https://github.com/shrinkwrap/resolver to resolve Splitlog dependency and then merged it with the test archive. See how to use Splitlog in its documentation. Give it a try!
