[jboss-jira] [JBoss JIRA] (JGRP-1001) Use byteman to inject faults for testing

[Bela Ban (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1001?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12654309#comment-12654309 ] 

Bela Ban commented on JGRP-1001:
--------------------------------

I created a new dir 'byteman' under tests, containing all byteman tests. The first example is RingBufferTest, which disturbs the thread interleaving to produce a bug when adding and removing the same seqno concurrently. The bug description and fix are described separately (probably in the byteman script file for the test)

> Use ByteMan (jboss.org/byteman) to simulate issues that can happen at runtime: do this in unit tests.
> For example: crash of merge leader after initial round (who frees the locks ?) (same for FLUSH)
